Reflectatherm Premier is a reflective vapour control layer with integrated tape for ease of installation. Reflectatherm Premier is for internal walls, ceilings and floors, specifically designed to enhance the thermal performance when placed on the warm side of the insulation.
The integrated tape, which is a key feature of Reflectatherm Premier, ensures an efficient, consistent, continuous and well sealed membrane to protect the structure from vapour and air movement.
