REFLECTATHERM PLUS ROLL
REFLECTATHERM PLUS ROLL
With an R-Value of 0.78 m2K/W, Reflectatherm Plus is the industry leading reflective vapour barrier.
It combines the highest thermal performance in its class with a high vapour resistance to prevent interstitial condensation.
Suitable for use in walls, ceilings and floors on the warm side of the insulation. 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.
Adjacent sheets should be lapped by at least 50mm and sealed with a suitable tape. Minimise penetrations caused by services and seal all joints.
