Allied Custom Gypsum 
More effective noise reduction. AccuQuiet Sound Mats provide enhanced noise control in wood-frame and concrete floor-ceiling assemblies in conjunction with the fire resistive properties of AccuCrete. AccuQuiet is easy to install and the water-tight fabric that supports the AccuCrete prevents leaks of cement slurry and excess moisture through to the subfloor.
Blue Ridge Fiberboard
Use SOUNDSTOP® to maximize sound deadening power from: Neighbor to neighbor - shared walls and corridors. Room to room - noise-generating media rooms, workshops, laundries, and children’s bedrooms and playrooms; offices and conference rooms. Outside in: dogs barking, traffic and industrial noises, trains and airplanes. 1-hour fire rated in a load bearing wall system when installed behind drywall.
Custom Building Products

EasyMat is highly versatile, and can be used for setting tile or stone directly over any acceptable subfloor. Dimensionally stable, EasyMat creates an exceptionally strong, bonded crack prevention system and delivers credible impact sound reduction.
Dura Undercushions
Dura’s sound control underlayments manufactured with recycled tire rubber (85% content), are a simple but very effective solution to creating floor systems which meet stringent sound ratings in multiple story dwellings (condominiums, hotels, apartments, private homes, and business applications). Can be installed under gypsum concrete, cement, wood floors, carpet, ceramic and vinyl tiles; all yielding the highest IIC ratings.
ECORE International 
QT Sound Insulation is formulated from resilient recycled rubber and installs directly underneath a variety of floor surfaces including ceramic tile, hardwood and stone to greatly reduce impact sound. QT is engineered to provide the highest IIC rating improvement over any other sound control product available.
