Acoustical Composites

Acoustical foam composites—demanding applications

Composites are ideal in applications that demand increased noise absorption, sound transmission loss, and/or vibration damping. Our composites contain a barrier material, a high-performance acoustical foam, and a 1/4″ foam decoupler. Key composite features are:

Easy to handle and install
One pound per square foot loaded vinyl barrier
Strong, durable bonds between layers are created by adhering the barrier directly to the foam

Acoustical composites
Acoustical composites are made of open-cell polyurethane acoustical foam and available unfaced or with a variety of film facings and peel and stick backings. Pattern: flat surface with thin face Sizes: 24″ ×48″ Thickness: 1″ Density: 2 lb/cubic foot Flammability: UL94HF-1 Facings: black tuftane, gray tuftane, aluminized mylar, reinforced aluminized mylar
Applications
Industrial noise control Machine enclosures Truck cab linings

Acoustical composite barriers
Acoustical composite barriers are made of open-cell polyurethane foam combined with 1# mass-loaded vinyl and available with a variety of film facings. Available in 1″ foam with or without facing, 1# mass-loaded vinyl, and 1/4″ foam. We can fabricate custom panels.
