These Acoustic corner blocks fit snug into the 90 degree angles of each squared room or placed in-between other foam mounts on the wall for aesthetic purposes. They are best used for rooms that are hoping to eliminate low frequency levels. If Bass Traps are not an option for you, these make a great second option.

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.
