SilentFX, featuring M2Tech technology, is a noise-reducing gypsum board specifically designed for systems requiring high STC ratings where acoustic management is needed. Viscoelastic polymer is applied between two specially formulated gypsum boards to dampen sound energy and significantly improve sound attenuation through walls and ceilings. SilentFX gypsum board is enclosed in a 100% recycled moisture and mold resistant face and back paper. As a result of the inclusion of M2Tech technology, SilentFX also contributes to indoor air quality by providing enhanced moisture and mold resistance.
