Any time you are transitioning from one floor to another floor of a similar height (within about 1/8 inch difference) a t-molding is required. It is also required to cover a break in a floating floor once the floor reaches certain run limitations. You can read more about that here. Our t-moldings are designed to withstand heavy traffic just like our flooring and come with the same wear resistant finish. Feel good knowing you are purchasing the highest quality transition pieces on the market.
