Mapei’s new Mapesonic™ 2, with a patent-pending design, delivers state-of-the-art sound-reduction performance with lighter weight and thickness. Next-generation technology incorporates sound reduction and crack isolation in a thin, flexible, lightweight, load-bearing, fabric-reinforced “peel-and-stick” membrane approved for ceramic tile, stone and wood flooring.MapesonicTM

The result of Mapei’s in-depth research into understanding sound, how it travels and how various materials and the dynamics of components work together to reduce that sound is a thinner membrane that delivers a 52 STC rating and a 50 IIC rating on a 6-inch (15 cm) concrete slab with no ceiling.

Mapesonic 2 is ideal for sound reduction in both residential (homes, apartments, condominiums) and light commercial (office buildings) environments. It provides reduced transmission of both impact sound (footsteps, dropped objects, etc.) and airborne sound (voice, TV, etc.) through floors. The membrane also helps prevent movement up to C\, inch (10 mm) wide from transmitting through flooring assemblies.
