DELTA® Sound Attenuation Fire Board
DELTA® SA-FIRE BOARD is a semi-rigid, medium density mineral wool acoustical and fire protection insulation. High temperature mineral fibers formed at over 2500°F are bonded together with a fire retardant binder. DELTA® SA-FIRE BOARD imparts excellent acoustical properties primarily to framed wall assemblies, especially when fire safety is the driving design consideration. DELTA® SA-FIRE BOARD may also be installed between joists in floor/ceiling assemblies with excellent effect. Typical fire/sound rated wall assemblies are listed in the Underwriters Laboratories Fire Resistance Directory and Gypsum Association Fire Resistance Design Manual. DELTA® SA-FIRE BOARD contributes significantly to both fire safety and acoustical performance.
