The Acousti-Mat® Floor Underlayment is used to increase sound isolation and reduce impact noise in wood, concrete and steel deck construction assemblies. This acoustic floor underlayment can improve the IIC (Impact Insulation Class) by up to 12 points over a wood frame and up to 20 points over concrete. Typical assemblies include wood frame, concrete, open beam, mass timber, and light gauge steel construction.

The Acousti-Mat® Floor Underlayment is made of extruded nylon filaments which form a three-dimensional core with a non-woven fabric, heat-bonded to its upper surface. This product is often a component in concrete and gypcrete floor assemblies. Acousti-Mat® has an impressive IIC and STC (sound blocking) rating for all assemblies, but carries no STC rating as a stand-alone material. The durable yet pliable construction of Acousti-Mat® sound control matting lowers structural sound transmission by its ability to convert and store vibrational energy.

Recommended applications for Acousti-Mat® floor underlayment include commercial and residential multi-story buildings such as condominiums, apartments, office buildings, hotels, schools, athletic floors and more. The Acousti-Mat® Perimeter Isolation Strip is used to isolate around the walls and other protrusions in the flooring when installing the Acousti-Mat® sound control mat. The product is extremely flexible and light, making it easy to install and handle.

Acousti-Mat acoustic floor underlayment may be used in new construction and renovations.
