Air-Tight 4'' IC Rated Recessed Lighting Housing for New Construction EFH4

They are designed with double-wall construction and non-combustible fiber insulation to prevent the passage of flames, toxic gasses, and ignition gasses into plenum ceilings. The fiber insulation also acts as sound deadening material, minimizing the transfer of sounds between floors. The EFH4 is suitable for condominiums, apartment buildings, multi-family, commercial and residential applications.
