Alreflex 2L2 Super R/Plus Insulation

Product Description

Alreflex 2L2 Super R is composed of a sandwich construction of bubble film and an exceptionally low emissive (higly reflective) aluminium foil. The product derives its high insulation value from the low emissivity of the aluminium. For this reason the extenal aluminium surfaces are protected from oxidation by a special coating which does not effect the emissivity value.

The 2L2 Super R system is a non-ventilated system with the roof structure partly contained within the insulation envelope creating a warm roof situation. The system essentially consists of two layers of 2L1 Super R in which a) the inner layer acts as a vapour barrier and to this end all the joints are taped b) the outer layer acts as the tile underlay and is permeable by virtue of its open weather lapped joints c) the insulation board between the two layers of 2L2 acts as void separator but allows the permeation of air through the gaps.
