Bamboo flooring is an investment and, when installed properly, it can give you decades of problem-free use. But with all wooden flooring, proper moisture protection is critical. As part of the regular maintenance of your flooring, we recommend cleaning up wet spills as soon as they happen. But what if the source of the moisture is underneath the floor? Protect yourself and your investment with this Sound Absorbing 3-in-1 Underlayment.
Expert Protection for Floating Floors
Designed for all floating floors, this product can be used with all of our Click Lock floors. It offers sound reduction: at least 72 decibels less with the super sound eliminator technology, in addition to moisture protection and cushioning.
Installation is easy. Just unroll the underlayment and run it the length of the room until the entire subfloor is covered. Tape seams together and the overlapping moisture guard edges prevent moisture from penetrating.
Why Do You Need a Bamboo Floor Underlayment?
An underlayment for bamboo flooring is an important ally that will extend the life of your floor and provide moisture protection and sound deadening. If you're installing onto a concrete subfloor, proper moisture protection is critical to prevent bubbling, blistering or peeling. Always test a concrete subfloor for moisture before proceeding with any flooring installation.
If our website lets you add your desired quantity into the shopping cart without showing a "this item is back-ordered" pop up notification, that means the product is in stock and ready to ship!
We highly recommend reading our Shipping Policy for a comprehensive explanation of our shipping processes.
We ship most freight orders (over 125 lbs) out within 4 business days of purchase, the average being 2 business days. For faster shipment of freight orders, we offer an Expedited Shipping option at checkout however please note that this simply means that we will ship the order out the next business day - it does not shorten the transit time once shipped. For small parcel orders we offer express UPS shipping options at checkout as well; please note that for express shipping services the order must be placed by 2pm EST in order to ship out that same day, otherwise we will process the shipment the next business day. We do not ship out orders, nor do the shipping companies deliver them, on weekends.
For residential lift-gate freight order deliveries, once the flooring order arrives at the local freight terminal, they will call you to schedule your delivery appointment, which is usually a 2-6 hour window on the day of your choosing (weekdays only) when possible. All deliveries are curbside as the freight companies do not offer inside delivery.
- You can purchase right on this website: add your desired items into the shopping cart, then click the cart icon at the top right of the website and click the "Proceed To Checkout" button.
- You can send an email with your desired materials list or purchase order to [email protected], and our support team will email you a quote with a payment button.

None of our products are brought inside the delivery location by the driver. All small parcel shipments are at the discretion and policy of the shipping company. All freight shipments are curbside delivery with lift-gate unless you specifically request freight dock delivery. Curbside delivery means they lower the pallet on the street at the end of the driveway. The drivers are not required to enter the property boundaries, although if not hazardous sometimes they’ll back up the driveway (if it’s flat and short) and drop the pallet on the driveway. Someone must be on-site to receive the delivery and inspect it for exterior damage, and then note any damage on the driver’s bill of lading (otherwise we can’t send free replacements). We highly recommend that you do not pay laborers to sit around and wait for the delivery, as the freight companies do sometimes miss appointments and they do not reimburse for such lapses. In some cases at the time of checkout, our website will allow you to add "Garage Delivery" for an additional fee, but this includes rolling the materials pallet into a carport or garage only, and terms and conditions apply.
For nail down installations we recommend that you use either 15 lb felt paper (asphalt-saturated roofing paper, essentially) or red rosin paper. Please note that 3 in 1 underlayment should only be installed under floating floors and should not be used in nail-down installations, as the compressive quality of the pad can result in loose nails, compromised structural stability, and noisy floors.
Yes, we sell several different products that provide sound insulation - underlayment and adhesive. To see these products visit our Installation Supplies page and check out our underlayments and adhesives. 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 soundproofing 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.
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 underlayment.
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 the 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. 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.
Yes, we may be able to accommodate this, but please note that we may still apply a small shipping and handling fee to your order. Please reach out to your sales representative for details.
Absolutely. We’ve shipped our floors to such far-flung locations as Guam, Kenya, Tanzania, Bahrain, Great Britain, Kuwait, France, Mexico, Canada, Hawaii, and many more. Please note that international shipments may require you to procure the services of a freight forwarder at the port of discharge; most port authorities can provide recommendations for reputable freight forwarders that service your home port. Also, minimum order quantities may apply to some countries. Call your Ambient representative today at (866) 710-7070 for shipping quotes to your country!
No, asphalt-saturated felt paper is NOT a moisture barrier (neither the 15 lb felt nor the 30 lb felt). It may help to slow down moisture and have some wicking qualities but it does not stop it. If you need a moisture barrier for a floating floor you will need to use a 3 in 1 underlayment. For a nail down floor, there is no vapor barrier underlayment available, so you will need to seal the moisture concern somewhere below the subfloor, or you will need to glue the floor down with a vapor barrier adhesive.
STC and IIC sound ratings indicate the ability of a material to muffle footfall noise and reduce sound transmissions between levels. An underlayment or adhesive with a high STC and IIC rating will not only reduce sound transmission between levels more effectively, but it will also reduce footfall noise within the room more effectively. Materials with higher STC and IIC sound ratings tend to be more expensive, and sometimes thicker, than underlayments with low sound ratings.
3 in 1 underlayment should never be used when nailing down a floor. These underlayments are nullified as a vapor barrier once you nail through them, and the compression of the pad results in the loosening of the cleats over time, which can result in noise squeaks and also structurally compromise the floor. Most installers use 15 lb asphalt-saturated felt paper when nailing down a floor, it reduces wood-on-wood squeaking and helps wick moisture away from the bottoms of the flooring planks (please note that 15 lb felt paper is not a vapor barrier!). Remember, if you're nailing down a strand woven bamboo floor it is required you use an 18 gauge cleat nailer.
At Ambient we value the brave men and women that serve in our nation's armed forces and law enforcement agencies. We offer a 5% discount off all products for active-duty members of our U.S. armed forces and 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.
For flooring and plywood we strongly recommend ordering a sample before placing your final order, so you can ensure that the shading will be to your liking. Our flooring and plywood samples have a dye lot number sticker on the back of them. Our website checkout process will ask you to type in this dye lot number before final payment; alternatively, if ordering via email or over the phone simply mention this lot number to your Ambient representative and we will update the order with it and ship that exact lot number. If we don't have that lot number available (it has sold out) but we have a matching lot, we will ship the matching lot. If we do not have a matching lot, we will not ship your order until you approve samples of the new lot.
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 variation 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).
If you receive the order from the exact lot number you requested, or you order sight unseen (you do not provide a dye lot number at checkout), and you decide after it arrives that you want to return the order, you will be responsible for return shipping charges. For flooring orders, please see our 30 Day Money-Back Guarantee for more information.
Yes you can! However you must use our urethane adhesive with vapor and sound retarder in combination with our Super Silencer underlayment. For maximum effect you can first glue the underlayment down to the sub-floor, then glue the flooring down to the underlayment. You will need a 1/4 in by 1/4 in v-notch trowel and some adhesive remover wipes are always recommended when gluing down any floor.
Cork underlayment is usually recommended because of it’s sound muffling qualities, but we sell 3 in 1 underlayments that have higher STC and IIC sound ratings than cork (meaning better sound muffling) so we normally recommend those. If you're gluing the floor down you can also use an adhesive that contains a sound barrier.
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 polyethylene foam (also called IXPE foam). The Sound Defender is a 3 mm thick gold-foil-backed rubber underlayment. Both have advanced moisture protection, shock absorption, and include an adhesive strip with overlap film for ease of installation.
