Soffit Liner 870

Soffit Liner 870

Soffit Liner 870 is a combination of a cement fibre building board factory bonded to a rockfibre lamella insulation layer.

The Liner is intended to provide a thermal insulation solution to the underside of soffit locations; the composite board is particularly suited for insulating soffits within car parks to the underside of office or apartment developments.

The Lamella backing is manufactured from high density rockfibre material that is orientated through 90 degrees and factory bonded to a cement fibre building board. This provides an enhanced insulation solution with exceptional strength capabilities.
