Our acoustic pyramid wedge foam is similar to our wedge foam in that it's high durability and great performance choice for deadening sound at an affordable price. It has a slightly different characteristic for absorbing sound than the wedge since it has four edges instead of two. It absorbs slightly less sound but has different usage styles.
Our four inch acoustic pyramid foam is the best product for maximum sound absorption. It's amazing at absorbing low frequency waves and works at its best in the largest areas such as concert halls, gyms or warehouses. We also offer many other sizes and variations of this particular style of foam.
We also offer this product in 14 colors in our other package selections.
All acoustical products meet ASTM E84 Class A and California 117 flame retardancy specifications. In simpler terms, this means that brief exposure to fire might cause the foam to flame, it would self-extinguish.
We do not encourage anyone to try fire retardancy tests due in any way, shape or form. Always make sure to check building codes to meet your area's regulation codes before installing any acoustic foam purchase from us.
