Features / Benefits

Engineered for performance — Acoustic Foam Panels are engineered to be an excellent sound absorption product at a low cost. Acoustic Foam Panels absorb sound generated at low, mid and high frequencies.

Quality — Acoustic Foam Panels are made with flexible, professional grade acoustic polyurethane foam. The foam keeps its color longer than other lower quality foams. Acoustic Foam Panels are firmer than other acoustic foam products on the market, which adds protection against rips or tears. The foam is consistent in density and firmness so acoustic performance will also be consistent.

Ease of Installation — Acoustic Foam Panels are lightweight and can be attached to a variety of surfaces. No special tools or materials are needed. Acoustic Foam Panels are available with a Pressure Sensitive Adhesive (PSA) backing for an easy peel-and-place application.

Fiber Free — Acoustic Foam Panels are safe to use in clean room, medical and computer equipment environments.

Flammability — Acoustic Foam Panels are manufactured from polyurethane foam that has a flammability rating of UL94 HF-1. Before choosing this product, be sure the flammability rating passes your local building code for exposed materials. For the best flammability rating see our Class A™ Acoustic Foam Panels.

Polyurethane Foam Warning

All Polyurethane Foams, including Combustion Modified Foams, will burn. Do not expose to any flame source. Once ignited, they can produce rapid flame spread, intense heat, dense smoke and toxic gases causing death. Warnings should be given to your employees and or customers. Test data does not necessarily reflect a foams performance under actual fire conditions. Before purchasing any foam, be sure to check with your local code officials to confirm the required flammability rating of exposed materials for your area.
