Mount Vernon Drywall Co. builds ceilings that measurably quiet the footsteps, voices, and noise from the space above. Real sound control is an assembly, not a product, so we decouple the ceiling, fill the cavity, and add mass rather than simply hanging thicker board. Resilient channel, mineral wool, and a layered panel work together to interrupt both airborne and impact sound. The result is a room below that feels genuinely calmer, not one that only claims to be.
The most effective single step is breaking the direct path that carries vibration through the framing. We install resilient channel, typically RC-1, to float the board off the joists, which decouples the finished ceiling and stops impact sound from passing straight through the assembly. On a ceiling, where footfall from above is the chief complaint, this decoupling does the heaviest lifting.
An empty joist bay lets sound resonate, so we pack the cavity with dense mineral wool, which absorbs airborne noise far better than standard fiberglass and adds a fire-resistance benefit. Filling the cavity is the low-cost, high-impact core of nearly every sound-rated ceiling we build. It works in concert with the decoupling above and the mass below.
Mass is what blocks the lower frequencies, so we often hang a layer, or a double layer, of 5/8" board beneath the resilient channel, sometimes with a damping compound between the sheets. That assembly converts sound energy to heat and cuts the bass and footfall that thinner ceilings pass straight through. Sealing the perimeter and every penetration with acoustic sealant keeps flanking noise from sneaking around the work.
Sound-rated ceiling assemblies from Mount Vernon Drywall Co. are built throughout Mount Vernon, NY and out into Eastchester, Tarrytown, Scarsdale, White Plains, and Pelham.
