StudiofoamPro presents a low-cost option for sound absorption in churches, restaurants, clubs, professional settings and other venues that require Class A fire-rated acoustical treatment.

It will not rot, crumble or suffer surface harm from normal use. Available in 2'x2' and 2'x4' charcoal grey panels. Features beveled edges similar to onoFlat and EliTE Pro Panels.
