TECH™ sound control underlayment is available in 3 thicknesses : 1/8, 3/16, 1/4 inch to meet the different needs of sound insulation.
TECH™ membranes also have other interesting characteristics; they are odorless, non allergenic, don't react to humidity and display a thermal film. TECH™ can be installed over a wood or concrete subfloor, either glued down or simply unrolled over it, according to the type of floor covering to install.
TECH™ membrane makes possible the installation of hardwood floors, engineered floors, floating floors or ceramic tiles in multi-family buildings such as condominiums while abiding by the regulations regarding sound insulation between apartments.
Furthermore, since the floor covering can be installed right over TECH™, with no need to add a plywood, the use of the membrane doesn't cause any floor elevation.
Cerami-Tech® thermo-acoustic membrane is conceived for ceramic and stone tiles installation over wood or concrete structures.
Cerami-Tech®, made from multi-composite fibers, is the only membrane on the market to combine these three properties:
Anti-fracture : protects from reflective cracking in your ceramic tiles and evens out minor subfloors irregularities.
Thermal : makes your ceramic tiles more comfortable, thanks to its unique reflective film. It also limits heat loss.
Acoustical : reduces impact and airborne noises for soundproofing your floor.
