RHB Foil Insulation is a mirror-finish reflective film, which provides good thermal insulation when combined with airspace in timber-framed walls. This allows a narrow wall thickness to be achieved while still reflecting 95% of radiant heat loss. In the summer, this insulation helps to keep the unit cool by reflecting radiant solar heat back to the outside. RHB Foil Insulation also reduces the problem of condensation affecting mineral-wool insulation.
Installation is normally made simple by applying RHB 1215 Foil Insulation to pre-manufactured wall frames across the inside face. The lining board is then stapled to the frame over the RHB1215 membrane, and the wall panels are then fitted to the steel walls of the unit.
