CONDENSATION CONTROL REFLECTATHERM PLUS Reflective Vapour Control Layer DESCRIPTION Reflectatherm Plus is a reflective, high resistance vapour barrier for internal walls, ceilings and floors, specifically designed to enhance the thermal performance when placed on the warm side of the insulation. The membrane should be installed with the foil side facing the cavity. In ceilings the product is placed between the underside of the rafters and the ceiling lining. In floors the product is placed on top of the structural decking or insulation (where present) and below any screed or sensitive floor coverings. Adjacent sheets should be lapped by 150mm and sealed with a suitable tape. Minimise penetrations caused by services and seal all joints.

U Value - Performance Ready Reckoner Stud Reflectashield TF & 0.28 Reflectatherm Plus * When utilising rigid insulation boards between studs, accommodation for services should be considered. The above calculations are based on fully filling the stud with insulation and the provision of a service cavity.
