egg sound absorption foam
Egg crate foam has convoluted egg-shaped peaks and valleys that provide increased sound absorption at higher frequencies over flat surface foams. Temperature range is
-40 degrees to +225 degrees F. Foam can be cut with a knife. An electric carving knife would also work well. Color is dark or black natural. Polyester-based polyurethane foam is strong and maintains its shape better than generic foam. This foam is specially formulated to absorb sound and is not the same as packing material foam or bed foam. 54" x 27 " sheets meet UL UL-94 Rating (self-extinguishing as to fire hazard) 3 inches to tops of peaks.NRC sound absorbing rating of 0.85. 1.05 is the best available rating in sound control standards.
