Our foam is specially made to withstand elements like harsh, direct lighting, the physical contact of manual handling, and of course, sound waves. Unlike other brands, our soundproofing foam will never crumble or harden, so the only cleaning required is the occasional vacuuming of dust. You can trust that our foam will remain soft and in sound acoustical condition for years to come
