1. ACOUSTIC FOAM MAT: Acoustic foam is a specialized acoustic panel made of polyurethane foam. These panels are acoustic mats up to 3 cm thick, with a 5 cm thickness for better absorption of low frequencies. A major advantage of our foam materials is their large lengths. 2. DOUBLE SOUND INSULATION: This acoustic foam panel consists of two layers. One layer is an absorbing egg crate foam, and the other is a sounddamping rubber layer for double sound insulation. 3. INSULATION: Dense, thick closedcell foam has a higher Rvalue than opencell foam, making it better at preventing heat from penetrating or escaping a structure. It also acts as a vapor barrier, reducing the ease with which water and moisture can enter the space, and the foam itself remains unaffected by water damage. 4. ACOUSTIC ENVIRONMENT: important for studios, recording studios, vocal booths, control rooms, offices, home studios, home theaters, game rooms, and home offices. Acoustic panels are for sound as they effectively control unwanted reverb and echo. Ideal for spot treatment in your studio or office.
