If you are looking for a test report please send an email to [email protected] and specify the product and type of report you are needing. We would be more than happy to email you a copy of any testing data that we have.

AbsorbaSound can be used in place of a cement board or uncoupling mat.

AbsorbaSound is a sound barrier that will help to reduce the transfer of noise between levels, in either direction.

AbsorbaSound is designed to be installed under your floor covering. We cannot attest to the effectiveness when used under an area rug.

AbsorbaSound is suitable for use under ceramic tile. We would feel confident in the use of our product in the application described, however we would recommend getting approval from the manufacturer of the uncoupling membrane as well.

AbsorbaSound comes in various thicknesses. The 2mm thick product, 200 square foot roll will weigh approximately 75lbs. Other thicknesses are listed on our spec sheet which can be viewed on the AbsorbaSound product page.

AbsorbaSound is not currently approved for use under turf products, as we have no testing data to determine suitability.

Worth Every Penny!

Works great to decrease the sound of foot steps in rooms below a second floor ceramic tiled surface. It cuts easily with a utility scissors but is near impossible to cut with a utility razor blade.
