F.A.Q. - About Our Products

Common questions about our products and company

Our prefinished strand woven bamboo & eucalyptus floors are 3x harder than traditional wood floors.  Go ahead – order some free samples and hit them with a hammer, dunk them in water, and ding them as much as you want – this is a floor that won’t look dented and scratched up in 10 years like a traditional wood floor.  In fact, you’ll most likely never even have to refinish your floor, saving you a costly repair in the years to come.

Bamboo is one of the fastest-growing plants on earth, which makes it a rapidly renewable and eco-friendly product.  The bamboo we use in our floors regenerates in as little as 5-7 years, and the eucalyptus we harvest from well-managed forests regenerates in as little as 3-4 years.  Compare this to a hardwood tree that takes 60 years or more to grow.

Our floors are installed and maintained exactly like traditional hardwood floors.  All of our floors come prefinished out of the box, so you won't have to do any messy or hazardous on-site finishing.  Installation of our flooring is done using the same exact methods as hardwood floors.  Since we sell mostly premium widths (wide planks) and premium lengths (3 to 6 footers) our floors also take less time to install.

Our bamboo and eucalyptus floors can be glued down to concrete or plywood, and nailed down to plywood.  All of our tongue and groove floors can be directly glued down to concrete, all you have to do is use an adhesive that contains a moisture barrier.  We recommend Bilder’s Ultimate All-In-One but there are many adhesives on the market that will work.  Otherwise if you want to float the floor, simply use one of our click-lock engineered floors. 

All of our floors are safe for you and your family.  Our annual test reports show that our floors emit "effectively zero" dangerous chemicals.  We take your health very seriously, as if it were our own – that is why many of our own employees have our floors installed in their homes.  Check out our low emission formaldehyde free (NAUF) bamboo floors.

Our floors hold up great in beach houses, mountain cabins, and any other location inside the U.S.  Our floors are moisture-balanced to work in every U.S. environment.  We do recommend that you keep the humidity range between 35%-55% as per the National Wood Flooring Association standards.


Bamboo Flooring versus Hardwood Floors

Quality matters, especially with bamboo.  What really sets Ambient apart from other brands is our unparalleled quality control process, which takes place before, during, and after we manufacture our products.  A quick web search about complaints and reviews will show you that our quality is without peer in the industry.  In over a decade of business we've never received a single complaint on our Better Business Bureau account (for bamboo flooring brands this is unequaled).  If you want to see some more reasons, check out our Why Ambient page.

The environment matters.  Our floor materials are all sourced from well-managed forests.  All of our floors are Lacey Act compliant, which ensures they're legally sourced with minimal damage to the environment.  All of our adhesives are zero VOC and our floor finishes are all ultra-low or zero VOC as well.

Low prices for high quality.  Since we're the only bamboo flooring brand that doesn't sell through distributors or resellers, you truly get the lowest prices on the highest quality floors.

Lot-specific ordering.  Every Ambient flooring order all comes from the same lot – so you don’t get shade patches in your floor.  Furthermore, each of our samples has its lot number written on the back – just mention that lot number when ordering and presto – your flooring order will come from that exact lot so you know that your final floor will match your sample.

All of our products are safe for you and your family.  If you're looking for safe, ultra-low emission floors, look no further.  We've proudly achieved Floorscore certification, and our annual test results show that Ambient floors emit "effectively zero" formaldehyde emissions.   We take the health of our customers very seriously, as if it were our own – that is why many of our employees and their families have our floors in their homes.

We are a one-stop shop.  We stock all the matching trim, moldings and installation materials for our floors, and we ensure that the moldings we ship you actually match your floor.  We ensure that you have a finished look that will get compliments for years to come.

We specialize only in strand woven bamboo and eucalyptus floors.  We helped pioneer the market in these incredibly durable and beautiful products.   Because of our experience, we have one of the lowest claim ratios in the bamboo flooring industry – almost zero.

Don’t take our word for it – do a web search.  If you do a web search on our company name vs other brands you will see we have earned a reputation for quality that is unequaled.  We guarantee that if installed correctly, our floors will not shrink, buckle or warp – problems that can plague other brands.

The best way to see variation is to check the installation pictures we have on all of the product detail pages on our website, or check out our bamboo flooring pictures gallery page.  The thing most homeowners like is that all of our floors have some variation, as they are natural products; this is what makes them unique and appealing as compared to laminate or other synthetic materials.  The carbonized color will usually have the most color variation within each lot, followed by some of the lighter stained colors.  Remember that you can always control the color of your installation – at the beginning of the installation itself you can simply point out to your installer which planks are too dark or too light, and ask them to leave those planks out of the installation.

Solid bamboo flooring is made solely of bamboo - it is 100 percent bamboo throughout, and is available in tongue and groove and click lock floating versions. (you can see an image of a solid click lock floating floor below).

Engineered bamboo flooring is comprised of a wear layer of bamboo on top, with an engineered, multilayer core below. The benefits of engineered wood floors are ease of installation and higher dimensional stability.

Ambient's floors are 100% safe for you and your family. In fact we're one of the few companies that test all products annually to ensure they fall within the CARB Phase 2 indoor air standard, which is the most strict in the world, and we've also achieved Floorscore Certification.  The CARB Phase 2 indoor air standard requires less than .05ppm off gassing of formaldehyde, and all of our floors consistently test at under .015ppm which is considerered “Below the Limit of Qualification” or “effectively zero”. We highly recommend you check out our safety information and testing page as well as our informative article here. As you might know, formaldehyde is a naturally occurring substance that even our bodies generate, so no substance on earth is truly "formaldehyde free", but Ambient solid strand woven floors are NAUF (no added urea formaldehyde).

More info about formaldehyde.  Formaldehyde exists in a wide array of household products including paint, wood furniture finishes, and cleaning supplies amongst others.  Formaldehyde is also a naturally occurring substance found in air. 

More info about CARB Phase II.  We recommend further reading from the California Air Resources Board: Click Here

The adhesives that we sell are moisture-cured urethane adhesives.  These types of adhesives cure (dry) faster when the humidity levels are higher. This is why adhesives usually come with a tack time and a cure time in relation to temperature and humidity. Thus, the same pail opened in Florida may dry in 12 hours where it may take 16 hours in Colorado. We recommend allowing the adhesive to cure at least 12-15 hours before walking on it, and 24 hours before moving heavy furniture back into place.
All bamboo flooring is made in China (like 90% of other materials in our homes).  In fact, many wood floors, regardless of where they're sourced (Brazil, Russia, Canada, etc), are shipped over to China for milling and finishing, and then shipped back to the U.S.  Specifically, our raw materials originate close to our factory group,in the Zhejiang province south of Shanghai, the traditional hometown of bamboo.
Phyllostachys Pubescens aka Phyllostachys  Edulis (Moso/Mao/Hairy bamboo).  Do not worry, this species is not eaten by pandas!

Yes, we sell multiple products that provide sound insulation for homes and businesses.  Many condominiums have sound insulation requirements for flooring.  There are two sound tests that are the industry standard for sound insulation: IIC and STC.  We have ratings as high as 83 STC and 85 IIC for underlayments and as high as STC 70 and IIC 66 for adhesives. The biggest benefit to using our high STC/IIC underlayments and adhesives is that you do not need to buy cork or other sound proofing and then pay someone additional to install it. Just float the flooring over the underlayment or glue the floor down using the sound reduction adhesive and you can substantially reduce sound transmission between levels in your home as well as muffling sounds from footsteps.

By using our high STC/IIC underlayments and glues is that you don’t need to buy cork or other sound proofing and then pay someone additional to install it. Just float the flooring over the underlayment or glue the floor down using the right adhesive and bada-bing-bada-boom, you’ve got a sound retarder!

FLOATING FLOORS.  In order to choose the right underlayment you have to ask yourself two questions: Do I need moisture protection, and how much am I willing to pay for sound reduction. When installing over concrete or over a crawl space, an underlayment with a moisture barrier (usually a thin layer of plastic or foil) is a must-have. This protects your wood floor from moisture rising up and damaging your floor from beneath. These are called 3 in 1 underlayments.

What are the 3 features of a 3 in 1 underlayment?

1) Moisture/vapor barrier
2) Impact absorption and sound transfer reduction
3) Cushioning for comfort

Remember that you will still need your sub-floor to be very flat before you begin installation, as the underlayment only accounts for minor sub-floor imperfections. The second question having to do with how much sound reduction you want is simple - all underlayments have STC and IIC ratings that tell you how much sound they block. The lower the rating, the higher the echo or knocking sound when you walk on the floor. An underlayment with a 70+ STC and IIC rating will muffle noise much better than an underlayment with a 50 STC rating. As you may have guessed, underlayments with higher STC and IIC ratings are more expensive due to the quality of the materials or thickness of their construction.

Maybe.  Keep in mind that wood flooring is a natural product and so there may be differences in shade and color between different lots.  We recommend that you send us a small 6 inch sample of your current floor to the address on our contact us page – this way our warehouse manager can check our existing lots to ensure we have something that matches first, so that you do not end up with a big shade patch in your floor.

One of the things that makes Ambient stand out from other brands is that we do not sell random length planks. All our floors come in standard lengths of six, four, and three feet depending on the product. Our Copenhagen XtraWide click bamboo flooring is the exception with both four-foot and two-foot planks included in every box.

One of the benefits for this is that you will have a lot less waste as with random lengths you are usually left with a lot of the smaller pieces that you will not be able to use. You can still achieve the randomized look of the flooring planks by cutting the starting plank in each row at a random length.

The great thing about strand bamboo and eucalyptus floors is that it is highly unlikely you will ever need to refinish them at all, because the floor will not be dented up and the finish will not be peeling off after 10 years like many wood floors.  That being said, all of our strand woven solid bamboo floors can be refinished 2-4 times and all of our engineered floors can be refinished up to 2 times.  The wear layer on our engineered bamboo flooring is not a thin veneer like other brands – it’s a thick wear layer that can be refinished.  

Refinishing bamboo flooring is a bit more time consuming than hardwood flooring, due to its density and the toughness of our finish, however it can definitely be done.  The finish on our flooring can be sanded down/off, and then a clear coat (polyurethane) finish can be applied, on site.  Pleae note that strand bamboo flooring cannot be stained before the clear coat is applied.  So our floors can be refinished with a clear coat, but they cannot be stained a different color. The density of the strand material prevents it from absorbing color stains that are applied onsite - the flooring will only absorb the stain in a controlled finish line environment.  Therefore yes, our floors can be refinished and a clear coat polyurethane can be applied but the final color of the refinished floor will be the color of the base material (natural or carbonized).

Should you ever choose to change your floor color or refinish your bamboo flooring, no problem - we've got step by step instructions for you right on our How To Refinish Bamboo Flooring page.
Our floors are installed in restaurants, spas and other high traffic and locations around the world.  Small water droplets that land on the floors will evaporate, however if you leave a puddle on any wood floor for more than 20 hours it will most likely mark the finish, and the wood may swell and stay that way.  Bamboo holds up a bit better than eucalyptus as it retains it's shape better after water absorption.  Hardwood floor warranties (including ours) do not cover damage from water, so if the planks are warped and don't retain their shape you'll need to cut them out and replace them.  Due to their hardness, bamboo and eucalyptus floors are great for kitchens as long as you avoid puddles and protect them with a normal level of care.  
Our floors are warranted in half baths/powder rooms but we don’t warrant our floors for use in full bathrooms because water may spill outside of a bathtub.  However many of our clients use them in full baths any ways, they just ensure to use rugs at the entrance to showers and make sure not to leave puddles. 
We do not. Laminate floors are made from synthetic materials (usually an HDF core with a paper wear layer and finish ) and while they can resemble wood floors at times, they don’t have the beautiful natural variation that real bamboo solid and engineered floors have, and usually they aren't as safe from an off-gassing perspective.  Here's a great write up of Laminate VS Bamboo Flooring that highlights the differences.

In general, bamboo and hardwood floors are much less toxic than almost all other flooring products.  Read below for more differences.

Bamboo vs Eucalyptus.  Our strand woven bamboo and strand woven eucalyptus floors are exactly alike when it comes to durability, installation and maintenance, but different in a few other ways.    Here are the main differences:

     1) Most of our bamboo flooring options come in 6 ft and 3 ft lengths, whereas our eucalyptus floors come in 4 ft lengths (as well as eucalyptus moldings).  They are both available in wide plank.
     2) Aesthetically, eucalyptus flooring shows the round knots in the grain, while bamboo shows the nodes from the bamboo culm.

     3) When submerged in water bamboo reacts slightly better than eucalyptus. I.e. if a spill is left on the floor for more than 20 hours, bamboo often regains it's shape once it dries out, while eucalyptus (and most other hardwoods) do not. 

    4) Durability-wise, both strand bamboo and eucalyptus have Janka hardness ratings that far exceed other hardwoods, so they both stand up very well in heavy traffic.

     5) Both strand bamboo and eucalyptus will hardly (if ever) need to be refinished in a residential setting, however they can both be refinished if needed.

Bamboo vs Laminate.  Bamboo floors are comprised of real bamboo wood, whereas laminates are made from synthetic plastic materials.  Laminate is often more affordable and in some cases easier to clean but will often curl at the edges of the planks if affected by moisture or water.  Real bamboo floors have natural variation and warmth that is hard to replicate in synthetic materials.  

Bamboo vs Tile.  Tile is much easier to clean (you can use abrasive cleaners) on a day to day basis, but grout upkeep can add an unwanted maintenance dimension.  Tile may also chip when heavy and sharp items are dropped on it.  Tile is more economical but does not have the warm feeling underfoot and is often cold to the touch on your feet.

Bamboo vs Cork.  Cork is also a great, sustainable flooring option and has a nice soft feel on the feet.  It is also very easy to clean and responds well to water.  One drawback is that the surface layer on cork can be damaged much easier than bamboo and does not wear as well over time.

Bamboo vs Hardwoods.  Bamboo is installed and maintained much like other hardwoods.  Bamboo is much more eco-friendly than most hardwoods as it regenerates in just 5 years compared to 40-100 years for some hardwoods.  Bamboo flooring costs are also usually much more affordable than hardwood floors, since it grows so much faster.  Bamboo flooring is head and shoulders above hardwood floors in terms of hardness, and it rarely if ever needs to be refinished.
Bamboo vs Carpet.  Up front costs for carpet can be much lower than bamboo and hardwood flooring, and it is soft underfoot.  However due to its tendency to trap allergens, dust mites, smells, and stains, it requires more cleaning and replacement at shorter intervals over time, which actually makes it more expensive in the long run.

Bamboo vs Stone or Concrete.  Stone is a very durable floor that can be very beautiful, but it is cold and hard underfoot.  Natural varieties have nice natural variation like bamboo hardwood floors.  

All of the floors we currently stock come with our proprietary matte, (all are pre-finished) long lasting Accuseal Finish.  We can manufacture all types of bamboo floors for you including high gloss, custom stains, and unfinished bamboo floors, but there is typically a minimum order quantity of 5,000 square feet and a 90-120 day lead time.
These all have to do with the color of bamboo flooring, and carbonized bamboo flooring also relates to the manufacturing process.  The term natural refers to the natural color of bamboo - this is the true color of bamboo raw material. Natural bamboo that is heated in kilns becomes "carbonized" or "caramelized", because the sugars inside the bamboo heat up and turn a nice rich brown color. So when natural bamboo has been heated up/baked turns into the carbonized color. Natural and carbonized bamboo are the only colors that go all the way through the plank. When a bamboo floor is stained (not natural or carbonized), the stain is applied to the top layer just like any other wood floor (for example, oak comes in natural and gunstock - gunstock is a stain). Since strand woven bamboo floors rarely need to be refinished, this usually isn't a big deal, however if you refinish any floor having a stain you will lose the stain color. The material underneath a stained bamboo floor may be either carbonized or natural depending on what product was used to hold the stain.

Ambient classic bamboo flooring looks like traditional solid bamboo flooring, with visible bamboo nodes. It is made of whole strips of bamboo bonded together in either in a horizontal or vertical pattern. Our classic bamboo flooring is a bit stronger than oak flooring. Properly installed, it can be used in almost any space except basements and bathrooms.

Ambient strand woven bamboo flooring looks more like traditional hardwood flooring, but it is extremely hard -- in fact it's almost 3 times harder than oak flooring. Strand woven floors are made by heating long strips of bamboo, which are pulled apart into strands, woven together, then compressed them under extreme pressure and heat. (Our strand woven flooring is harder than most because the machines we use compress more material, increasing the floor's strength and durability.) Our strand woven bamboo flooring is extremely durable, pet- and family-friendly. So you get the strength and eco-friendly aspects of bamboo with a hardwood look.

The only difference is in their appearance. Horizontal grain planks have wider bamboo slats because the bamboo strips are laid flat before melding. Vertical grain planks have narrower bamboo slats that have been turned on their side when melded. Both patterns have been used in a wide array of beautiful spaces, including bamboo stair boards and moldings. It really just comes down to personal taste.


Bamboo flooring is installed in the same manner as hardwood flooring and installation costs in the US can range anywhere from $2-$6 per square foot depending on the installation.  Small square footage amounts will result in a higher per square foot installation cost.  

Installers will modify their pricing based on a variety of factors such as: moving of furniture, removal of existing flooring, leveling of subfloor, installation moldings required, inside delivery charges, to name a few.  Some installers (mainly from flooring stores) will try to convince you to buy their floor brands so that they can make money off the products as well as the installation.  Any carpenter, handyman or homeowner can install our floors, we just recommend you follow our handy-dandy bamboo flooring installation guide.

No. Rolling office chairs tend to collect grime, dirt and small rocks under the wheels, which eventually will damage the finish of any wood floor including ours.  You always want to use a chair mat under rolling office chairs.  It is also advised that you use felt pads under furniture and chairs to avoid damaging the finish.

Buy a High Quality Brand, Problem Solved.  Like any other product, quality can vary immensely from brand to brand.  Always follow the cardinal rule when buying durable goods: do your homework!  Make sure to check review sites like Yelp, Reseller Ratings, Ripoff Report and the Better Business Bureau - this is the best protection you have against buying faulty or low quality products.  You should always search on the brand names you are considering, and complaints or reviews.  A large majority of the problems can also be attributed to common installation errors, but as long as your installer reads the installation instructions that won't be a problem.

Bamboo Floor Shrinkage. In relation to bamboo flooring shrinkage (shrinking planks pulling off walls and planks separating away from each other), there are several culprits that can cause this problem.  This is an issue that happens not only with bamboo flooring but also affects wood flooring in general, and it's a problem that plagues low-quality brands and also low-quality installers. 

Bamboo Floor Scratching.  There are two basic types of scratching that you see complaints about.  The first type is scratching on old bamboo floors (what we call "classic" bamboo - horizontal and vertical), and small white scratches on the surface of strand woven bamboo flooring.  If you purchase a floor that has the word Vertical, Horizontal, Edge Grain, or Flat Grain in the name, you are purchasing a floor that is about 1/3rd the hardness of strand bamboo flooring, and mid-range in terms of hardness for wood floors.  If scratched with something sharp, these floors will show a white mark on the surface and it may also dent the wood which will stay there for the life of the floor.  This happens on almost all hardwood floors.

The second type is scratching on strand woven bamboo floors. On these floors, a very sharp scratch may leave a small white micro scratch on the surface, but typically it will not leave a groove in the flooring itself due to the density and hardness of strand woven bamboo/eucalyptus.  This is what separates strand woven flooring from it's traditional hardwood counterparts.  Also, believe it or not, these micro scratches will actually buff out over time under normal foot traffic.  To see this for yourself, scratch one of your samples, then put it on the floor and apply weight to it with the toe of your shoe, then swivel your foot a little while - you'll see the scratch buff out before your eyes.

Another quick fix for these scratches is to dab the scratch with a bit of mineral oil, which minimizes them.  Most strand woven bamboo and eucalyptus floors, and some wood floors, are coated with aluminum oxide polyurethane finishes - and these are very expensive coatings - the reason being that they have a very long life and will most likely never need to be refinished.

Even though all of our floors have several UV protection layers added to our Accuseal Finish System, most wood floors will fade slightly over time if exposed to constant and direct sunlight on a daily basis.  There is no object on earth that will escape the effects of constant and direct sunlight.   Do not fear, as you can protect your floors, furniture, and other household items from the rays of the sun by using window films and drapes that filter UV light.  A quick web search will turn up a myriad of products that will help preserve your interior furnishings from sun rays.

If you live in the US and you have any flooring (bamboo or other) that is facing in a southerly direction and in direct sunlight, we recommend that you install the UV films on your windows, or consistently move furniture and rugs around as to avoid resulting shade differences in your floor and/or furniture.  

Yes, Ambient is proud to be FloorScore® certified!  FloorScore is a voluntary certification program whereby floors must meet the most stringent indoor air quality  standards in the world to gain certification.   You can find Ambient's full test results and other technical information on our ultra-low VOC bamboo flooring information page or learn more about the Floorscore® program here.

For the most up-to-date information we highly recommend you visit our Bamboo Flooring and LEED Credits page.  But in general, all of our floors contribute to LEED credit MR6 6.1, which rewards building materials derived from rapidly renewable materials (1 pt), and some of our floors contribute to LEED IEQ 4.1 Low-emitting Materials for composite wood and LEED IEQ 4.1 Low-emitting Materials for adhesives and sealants formaldehyde (1 pt)

Our floors are all NAUF (no added urea formaldehyde).  Small amounts of non-toxic phenolic resins are added during the compression process in our strand woven floors to increase bonding strength, so that the strands of wood fuse together more effectively.  This is resin is similar to those used to hold together the other wood furniture in your home, such as your kitchen table, your cabinets, your wood desks at home and at work, your dresser drawers, closets, shelves, etc.  All of our products are tested by an independent 3rd party laboratory every year to ensure they don’t emit dangerous toxins and all of our products fall within the CARB Phase II standard which is the most strict in the world. We are also Floorscore certified, so our products are perfectly safe for indoor use!
All of our floors have micro-beveled edges.  The reason for this is because square edges can splinter up or chip off when kicked under normal foot traffic.
The ability of a substance or part to retain its shape when subjected to varying degrees of temperature, moisture, pressure, or other stress.  Engineered floors are typically a bit more dimensionally stable than solid floors (they expand and contract a little less) however this mostly comes into play with floating vs nail/glue down.  Engineered floating bamboo floors are very stable, conversely when you are floating a solid bamboo floor (solid means the plank is wood all the way through, and floating means the planks are clicked or glued to each other instead of being nailed down or glued down to the sub-floor) you must have very strict humidity controls inside your home or it may pull apart and out from under walls (even if it is click lock).  Remember that to float a solid bamboo floor you must keep your successive flooring "runs" to less than 15 feet tangentially (across the widths of the planks) and 25 feet longitudinally (down the lengths of the planks.)
It grows fast, does it not?  Unfortunately some of the species of bamboo that have been planted in the U.S. are of the variety that have deep underground runners, and it is therefore very hard to control.   While we would love to recycle that wood and make something new from it, unfortunately our manufacturing facilities are overseas, which means we would have to ship it across the water.  This would negate any benefit derived from taking that bamboo off your hands.  We recommend that you try to do something creative with it, like making picture frames, furniture, and other cool uses like making a bamboo bike!

While bamboo flooring can usually be exposed to cold weather for short periods of time (less than 24 hours) without problems, prolonged cold weather exposure is not recommended for any type of hardwood flooring, including bamboo.  As a general rule, wood and bamboo flooring will perform best when the indoor climate is maintained at around 40-60% humidity and 60-80 degrees Fahrenheit, although conditions may vary in different geographic areas. Hardwoods left in cold weather (below 40 degrees Fahrenheit) for extended periods may result in face checking, shrinkage, and even cracking.

All of our engineered floors are warranted for use in basements, you simply have to put down a 3 in 1 underlayment before installing the flooring.  Remember that you'll want to acclimate the floors in the same room in which they're going to be installed at least 72 hours prior to installation, and be careful not to acclimate them directly on concrete or over crawl spaces as they will absorb moisture, which will cause problems.  Instead, ensure to lay down an 8 mil thick plastic sheet or 3 in 1 underlayment for the boxes to sit on during acclimation, and you'll want the apron of the sheet to extend about 1 foot away from the boxes themselves for added protection. The interior humidity settings of the basement must be maintained between 40%-60% just like on any other level in the home.

STC and IIC sound ratings indicate the ability of a material to muffle footfall noise and reduce sound transmissions between levels. An underlayment with a higher STC and IIC rating will not only reduce sound transmission between levels more effectively, it will also reduce footfall noise within the room more effectively.  Underlayments with higher sound ratings tend to be more expensive, and sometimes thicker, than underlayments with low sound ratings.

There's a common misconception that thinner floors are less sturdy than thicker floors.  This is only true if you buy cheap engineered hardwood floors that have a razor thin veneer layer, because it can't be refinished, and it's often easily broken through when you drop something heavy on it.  Conversely, every one of our floors can be refinished a minimum of 2 times including our engineered bamboo flooring (which have a substantial wear layer). 

In fact, all of our floors come with a lifetime structural and finish warranty regardless of thickness.  The driving factor between whether to choose thick over thin is usually a matter of the layout of your home and subfloor.  Some people get thinner floors to increase the headroom in their homes, while others choose thicker options so that they can more easily transition to other floors on the same level without using transition pieces.  Sometimes door frame heights are also taken into account when choosing thickness.  Also, if you want 6 foot lengths, those usually require greater thickness to remain stable, while 3 foot lengths can use a thinner plank and retain their dimensional stability.
Any order over 3,000 square feet gets sent to our discount department for further consideration, and we can usually call you back quickly with custom pricing.
The following moldings come in 6 foot lengths for bamboo and in 4 foot lengths for eucalyptus:  T Molding, Stair Nose, Quarter Round, Thresholds, Baseboards, Cove Molding, Spline and Reducers.  Our stair treads come in 4 ft lengths and we also carry some 6 footers in certain colors.  To see the exact dimensions of any of our floor moldings, just click through to that product's detail page and you will see dimensions diagrams. To see all of our inventory check out our bamboo moldings & trim page.
All of our materials are rapidly renewable and regrow in 4-7 years, and are harvested from well-managed or FSC-certified forests.  We pay fair prices for our bamboo which is harvested by local farmers in the provinces where our factories are.  The farmers harvest the wood by machine and by hand with some methods dating back centuries.  We ensure to only harvest bamboo culms aged 5-7 years, and take our stock from the middle of the culm.
All of our bamboo is harvested between the ages of 5-7 years which is the optimum age for use in flooring applications.
All of our factory partners are ISO9001 and ISO14001 certified.
No.  We use only Moso bamboo, and pandas do not eat this bamboo species.  Furthermore, we use bamboo from the Zhejiang province, an area that pandas do not inhabit.
If you live on the West Coast and buy an Oak or Maple floor (which comes from the East), there is more embodied energy in that product than a bamboo floor made near the coast in China and shipped over the water.   Ocean freight is simply that much more efficient.  And this does not even take into account the fact that the tree cut on the East Coast will take 50 years to grow back and the bamboo tree cut in China will take 5 years to grow back. 

One interesting tidbit that people don't know is that a large chunk of wood flooring (apart from bamboo) harvested in Canada, Russia, Brazil, etc, gets shipped over to China first for milling and finishing, and then gets shipped back over to the US, which in effect doubles the transportation distance and CO2 emissions.

Large pets and active children are just a few of the reasons why families purchase our strand woven floors. Our floors resist scratching from pet claws extremely well!   Strand woven bamboo and eucalyptus floors are the hardest wood floors on the market and are used not only in residential locations but also commercial locations around the world.  Our strand woven bamboo flooring can take a lot more punishment from denting and liquids than most other floors. 

Please note however that no floors are impervious to pet urine – even concrete will be stained by pet accidents! That being said we have many past clients with dogs, pets and active lifestyles that rave about the durability of our floors.  Order a sample today and hit it with a hammer, dunk it in water, and scratch it up, you'll see just how tough the finish and wood is for yourself.

1.    What type of subfloor (usually plywood or concrete) will the floor be installed over?
2.    Do you already have a specific plan to float, nail, or glue down the floor, and if so, why?
3.    What other types of flooring will the floor be butting up to?  Will you require transition pieces and how many?
4.    How much flooring will you need to complete the job?  Have you added 10% for cutting and waste?

Janka hardness is a way to measure the strength and durability of various hardwood flooring species.  We have a great write-up about bamboo and Janka testing on our site if you want to delve further into this matter.  Most of our bamboo and eucalyptus floors range between 4,000-5,000 on the Janka scale.  Depending on the time of the year the raw materials are harvested and the location on the plank where the lot was tested, different lots may have higher or lower Janka ratings than advertised; this is true across all brands.  Additionally, extremely high density can sometimes cause finish problems down the line as they are less permeable and thus don't hold finish well. Our Accuseal finish system has optimized flooring density and finish bond to provide the best finish on bamboo flooring.
Absolutely!  If you purchase now in full and then wait to have your floor shipped for at least 90 days, you may qualify for a substantial discount depending on how much you purchase.  Please call your Ambient representative for more details.
At Ambient we value the brave men and women that serve in our nation's armed forces and law enforcement agencies. We offer a flooring discount of 15 cents per square foot for active duty members of our U.S. armed forces and active duty full-time local and state law enforcement. Clearance items and odd lots do not qualify for this discount and it cannot be combined with other promotions.

The main reason the hardness shows up differently between engineered and solid versions is because the engineered floor has an hdf or multi ply core that compresses more easily under the weight of the Janka ball testing machine.  In fact, the wear layer of the engineered floor is comprised of the same strand woven wood material that is in the solid tongue and groove version (which shows the higher hardness rating).  

In actuality, since the engineered floors have a bit of “give” or “bounce” in them due to their softer core, when something falls on them they’re actually somewhat more dent resistant than the solid versions when something is dropped on them. 

We do not recommend using our bamboo plywood for cutting boards or any other cutting surface.  Although our bamboo plywood meets the most strict indoor air quality standards and is perfectly suitable for use as cabinetry, wall paneling, and furniture, it is not manufactured to be food-safe when cutting directly on it (food safety standards are different than indoor air quality standards).  Our plywood can also be used as countertop material as long as food is not cut on the surface or as long as a food safe finish is applied which seals the unfinished bamboo plywood surface.
Cupping is most commonly caused by moisture hitting the bottom of the wood floor from the sub-floor.  Read this document about cupping, crowning and buckling in wood floors. This almost always means there is a sub-floor moisture issue, and usually requires destructive floor replacement.

Shrinkage can be the result of several factors: 1) the humidity levels have dropped more than 20% (in which case most every wood substance on earth will shrink), 2) the brand of bamboo you have installed is of low quality and was not properly moisture-balanced during manufacturing, and 3) you installed a FLOATING SOLID (all-the-way-through) wood/bamboo floor and exceeded the recommended run limits.  This can sometimes be remediated by installing a humidifier; however if the wood has become too dry there is sometimes a "point of no return."

Buckling is most commonly caused by the interior humidity increasing by 20% or more and is a result of the floor expanding and pushing against the exterior walls or interior structural elements.  This often results in two or more planks having a "teepee" effect as they push against each other and lift up.  This can be fixed by installing a dehumidifier for one week and then walking the planks to flatten them again.
To care for your hardwax oil floor you must follow the MAINTENANCE INSTRUCTIONS. You must use the professional Timberex Maintenance Kit, you can buy the kit and accessories such as maintenance oil and special cleaners securely on the internet. The products supplied in this kit will keep your floor looking like new and instructions for the use of these professional maintenance products will be found in the kit.  You may have to re-oil the floor every year or two to keep it looking like new. 
WHAT IS SPLINE?  During the installation of tongue and groove hardwood and bamboo flooring, often times it's necessary to reverse the direction of the floor.  In order to due this many installers use what's called "spline" to join the groove sides of two planks together so that they hold firmly in place.

WHERE DO I GET SPLINE?  You can purchase spline right here on our website! We sell three different thicknesses. But if you want to save some money, there are a few simple workarounds.  The most common method is for the installer to cut/router their own spline on the spot using one of the excess waste flooring planks, on a table saw.  Another common method is to use a 3/4" hardwood spline and adjust it down using a palm sander for a proper fit. 


1) Install a temporary "placeholder row" of sacrificial planks (you will pull these up later) following a straight chalk line (to keep subsequent rows straight).  It's best to use planks that have imperfections on top, however the edges should be mostly square.  This row will serve as the "brace" against which the subsequent rows will butt up against.

2) Install 3-5 rows of flooring planks in the same direction.

3) Carefully remove the first "placeholder row" of sacrificial planks using a pry bar.  Now you can glue in the spline, allow it to set, and then you're ready to start laying flooring in the other direction.  For a tighter fit, glue and nail the spline.  Titebond T&G glue works great.
They’re basically the same, just slightly different dimensions.  Please check this video out about the difference between shoe molding and quarter round.  We sell quarter round in bamboo but not eucalyptus, and we also primed white poplar shoe molding.  To see if we carry matching quarter round for a specific floor just click the thumbnail of that floor on our bamboo flooring category page and on the next scroll down to the Add Moldings strip near the bottom of the page – there you’ll see all matching moldings we carry for that floor.

Please remember that photographs on our website are taken from a variety of devices and under many different lighting conditions, and are viewed on a wide range of computer monitors and contrast settings, thus we do not guarantee that any floor will match the photographs on the website. If you order your flooring sight unseen (without receiving samples first), Ambient is not responsible for light or shading varation or differences and thus not responsible for return shipping costs (which can be expensive and can vary greatly depending on where you live and the size of your order). 

All of our samples have a lot number on the back of them, so simply mention this lot number at the time of purchase, and we will ship you the same boxes that your sample was cut from.  If you receive the order from the exact lot number you requested and you decide that you don’t want it, you will be responsible for return shipping charges. Please see our 30 Day Money-Back Guarantee for more information.

We do not manufacture stair parts other than treads and risers because they are difficult to keep stable.  Below are a few common methods installers use to match up your existing wood stair railings and stair parts to match your new bamboo or eucalyptus flooring.

1) Choose railings made from a different species of wood that match your floor color, or are a complementary color.

2) Sand down and stain your existing wood railings to match.

3) Paint your railings white, black or any other complementary color that suits your interior design.  White railing are the most common as they match up with white baseboard, quarter round and crown moldings.

Absolutely not - they're designed like this on purpose and this design will not result in "loose planks" once installed.  Especially on longer flooring planks there has to be some room for play simply to be able to click the planks together - it's done for ease of installation.  In fact one main complaint from installers about low quality brands is that their click design system is too tight and they have a lot of difficulty even getting the planks to click together.  Here at Ambient we're known for excellent overall quality and this extends to our milling machinery – in fact, installers comment all the time on how well-milled our planks are and how little waste they get when they install our floors.  


Most of our bamboo moldings come in 6 foot lengths unless otherwise noted below, and most of our eucalyptus moldings come in 4 foot lengths.  Please remember that moldings are sometimes difficult to match up to the floor exactly color-wise, as moldings are manufactured in large volume batches and must serve for multiple different lots of flooring (true for all wood floor manufacturers).  This batch manufacturing is what allows us to keep the moldings costs affordable.

T-Molding: This is used to transition between two floors of equal height or within 1/8 inch in height of each other.

Threshold: This is used to transition between two floors of unequal heights.  The bottom of this molding is commonly cut (ripped) as needed depending on the height of the lower floor.  Also commonly used at exterior doorways and sliding glass doors.

Reducer: This is used to transition down to the ground.

Quarter Round: Some installers call this shoe molding and although they serve the same purpose and are usually interchangeable they are slightly different dimensions-wise.  This molding goes all the way around the installation and is often paired with baseboard but not always.  It's used to cover up the expansion gap left around the perimeter of the installation.

Baseboard: This is used to cover the expansion gap all around the edges of the installation and is sometimes used with quarter round for a finished look.

Stair Nose: Also known as bull nosing, this piece is used to transition down to a lower level such as a landing, and at the top of a staircase.

Stair Tread: This is typically one entire piece to cover the stair step, we sell most of them in 48" lengths and some in 72" lengths.  Many of our treads come with two rounded sides and rounded front, so that they can be used on open stair cases.

Stair Riser: This is the vertical piece on the stair case in between each tread and they're usually 48 inches in length but we also carry some 72 inch versions.  We stock them for our most popular colors, and we also sell the white stained poplar risers which are very popular and usually more affordable than the matching wood risers.

Register Vent/Dampener Covers: We have mostly flush mount register vents with a removeable inner grill, but we also carry drop in vents in some colors.  We carry the most common vent dimensions of 4x10 and 4x12 but also some 4x20 versions in popular colors.

Cove Molding: These pieces are glue up under stair treads and noses to give a more finished look, where the nosing/tread meets the vertical wall or riser.  Most treads and noses aren’t finished underneath, so when you look up at them from below they’ll look nicer if you add a cove molding.

Spline: Bamboo spline helps transition when you change direction in your flooring planks. It allows you to place two planks (tongue sides) together and continue your flooring installation.


The IIC and STC ratings represent how much sound blockage there is.  For example a rating of 70 is a measurement of the total sound blockage for the whole system (floor + glue) when  installed on a 6" suspended slab with a ceiling system beneath. The Delta IIC is the difference in sound AFTER the barrier is put in. I.e. the Delta IIC reflects the change in impact insulation as a result of the floor and glue system. A Delta IIC of 20 is very good.  

If you'd like to know more we recommend reading this page: http://isostore.com/comparing-sound-ratings/


We have a couple of 3 in 1 underlayments, and the best way to see what each one is comprised of is to visit our bamboo flooring installation and accessories page and read the product details for each product. 

Our Super Silencer and Sound Defender have some of the highest STC/IIC sound absorption ratings in the market, are great for condominiums and for muffling foot-fall noise, and are necessary to install floating floors.  The Super Silencer is made from cross-linked closed cell polyethelene foam. The Sound Defender is a 3 mm thick gold-foil-backed rubber underlayment and both have advanced moisture protection, shock absorption, and include an adhesive strip with overlap film for ease of installation.

We stock only prefinished floors.  We do offer all of our natural colors (Natural and Carbonized Bamboo Flooring, Tupelo Honey Eucalyptus Flooring, etc) in unfinished planks however there is a 90 day lead time and a minimum order quantity requirement.  Please call us at (866) 710-7070 if you're interested in placing a custom order.

Our adhesives do not have any ingredients that are defined as volatile organic compounds “VOC’s”  as part of the formulas.  VOC is a regulatory description for “solvent” which evaporates into the air and is considered an air pollutant.  These formulas contain none, so we refer to them as zero-voc. We can calculate "potential" trace VOC values based on the vapor pressure of the individual raw materials used in the formula. Anything with a vapor pressure greater than 2 mmHG at 25C is considered a VOC for these calculations.   The results are as follows: Bilder's Ultimate has a VOC of  less than or equal to 0.77g/L . You can download the MSDS and TDS under the Specifications section here.  These trace values reflect the highest possible VOC content- prior to processing and evacuating at elevated temperatures.

•    Radford University Economics Building (2010)

Countless restaurants, spas, commercial and residential installations around the U.S. and the world including France, Bahrain, Tanzania, Guam, Kuwait, Mexico, and many more!


We are the manufacturer and importer of our own brand and we sell direct (not through distributors), so our prices are much lower than you’ll find at typical flooring stores for such a high quality product.   That being said we do often-times offer discounted/wholesale pricing once your cumulative orders with Ambient have exceeded 2,000 sq ft total. 

Many things, including the age at which it is harvested, the species, the part of the stalk (the middle) that is use, and the fact that we inspect all raw materials for irregularities before milling.  Also, most problems with low quality bamboo have to do with shrinkage, warping and cupping over time due to inadequate moisture balance control.  

Our moisture balancing process is strictly controlled and our floors all have stable moisture content, ready for use anywhere in the United States.  Most other bamboo flooring brands do not moisture balance their floors properly and this is why you see many complaints about them.


It is possible! However, before spending money to send us a sample of your floor, please visit our flooring overview page to see what colors and styles we offer. If you see that one of our floors might be a suitable match, please check the specifications listed on the overview page to ensure our floor plank length, width, and thickness is what you are looking for.

The final step would be to send us a sample of your floor so we can compare it to our stock. This is easier than us sending you a sample because we might have several lots of the same product, but we only send out one at a time. If you send us a sample, it allows us to compare it to every lot we have in stock.  Please send at least a 5 inch sample to the address on our Contact Us page and write Attn: Sample Check, and include your contact information and how much square footage you need.  Someone will contact you within 2 business days of receiving the sample.


Our ultra-tough Accuseal® Finish with aluminum oxide is quite simply the best bamboo flooring finish on the market, backed by a lifetime warranty.  It is a uv-cured acrylic oil-based polyurethane finish with aluminum oxide added in for additional durability. We use a proprietary process that endures abrasion better than any other bamboo floor on the market.  We have 10 high quality imported German coats on top and two on the bottom.  You will most likely never have to refinish this bamboo floor under normal residential traffic conditions. But if you ever need to refinish the floors, we have a handy guide for you here.

The same finish as on our floors, however due to the rounded nature of some moldings the finish is sprayed on instead of layered on in a finishing line.
