2.Standards in UL94 HF1
3.Easy to cut ,easy to install
Description:
Convoluted Acoustic Foam Panels are manufactured from acoustic grade polyurethane foam, in an “egg crate” design is designed to have an increased surface area, giving you better sound absorption performance. The material is flexible and easy to cut. Convoluted Acoustic Foam Panels are a cost effective solution for improving sound absorption by reducing echo and reverberation. Convoluted Acoustic Foam Panels are not just for recording environments, they can be used in equipment and machine enclosures, to reduce vibration and airborne noise propagation. This product is perfect for any application where acoustics are poor and budgets are tight. Convoluted Acoustic Foam Panels have a UL94 HF-1 flammability rating.
