 
Core construction is of thermo-molded medium density fiberglass to dampen resonance, resist impact, and will not resonate, warp, or separate. Optional 1/8" special laminate (ATP 1.1, 1.6, 2.1) concealed under facing provides extreme impact resistance plus the added benefit of increased low frequency absorption. Finished products are supplied to sizes as specified, ready to install with supplied fasteners for easy mounting to existing substrates.
Fire Performance
Composite assemblies with standard finishes have achieved a Flame Spread Rating of less than 25 (Class A) per ASTM E 84.
