About Foam

Contoured peaks gently cushion objects and damp vibration. These polyurethane foam-egg crate sheets are commonly used for packaging and insulating. Foam has open-cell construction, which allows water, air, and gases to be absorbed. These sheets come nested together in a set of two.

Contoured Sound-Absorbing Sheets

Also known as egg crate, these sheets have peaks and valleys that absorb more sound at higher frequencies than flat-surface sheets. Use them to quiet noisy areas and line machine enclosures. Sheets are made of humidity-resistant polyurethane foam.
