White Plains Premier Drywall builds acoustic assemblies to a specified STC rating, not to guesswork, for the boardrooms, hospitality suites, and demising walls where privacy is part of the design. Sound moves through both direct structural contact and air, so a real acoustic wall decouples the surface, adds mass, and fills the cavity as a coordinated system. We assemble resilient channel, dense mineral wool, mass-loaded vinyl, and double-layer board to hit the rating the acoustician or architect has called for. The result is a partition that delivers measurable, specified sound isolation rather than a vague promise of quiet.
Sound Transmission Class ratings describe how well a wall blocks airborne noise, and a rated assembly only performs if every layer is built as tested. We construct the specified assembly in full, from stud type and cavity fill to board layers and sealant, so the finished partition meets its STC target. Building the whole assembly correctly, rather than substituting or omitting a layer, is what turns a rating on the drawings into real isolation in the room.
The most effective way to stop vibration from passing straight through a wall is to break the direct structural path. We float the board off the framing on resilient channel or sound isolation clips so the finished surface is mechanically decoupled from the studs. This is central to high-STC boardroom and demising walls, where the goal is that a conversation on one side is inaudible on the other.
An empty cavity resonates, so we pack it with dense mineral wool to absorb airborne energy and add mass to block low frequencies. High-rated assemblies often carry a mass-loaded vinyl barrier and a double layer of 5/8" board, sometimes over a damping compound, to convert sound energy to heat. Adding calibrated mass and cavity fill is what pushes an assembly into the higher STC ranges the specification requires.
Executive boardrooms demand speech privacy, and hotel and hospitality suites demand guests never hear the next room, so both live or die on acoustic detailing. We carry the rated wall tight to the deck, seal every perimeter and penetration with acoustic sealant, and treat the flanking paths that quietly defeat an otherwise good wall. Closing those gaps is what makes the measured performance match the design intent.
Boardrooms and suites in White Plains, NY, Armonk, Chappaqua, Bedford, and Mount Kisco rely on White Plains Premier Drywall for STC-rated soundproofing and acoustics.
