incorporates a non-combustible fiber insulation to prevent passage of flames, toxic gases,
ignitable gasses into ceiling plenums. The cULus listed housing is rated for a minimum of
2 hours protection. The noncombustible fiber fill also acts as sound deadening material
eliminating the transfer of sound between floors. Suitable for commerical, multi-family
