Durafoil Ultra Double Foil

Durafoil Ultra Double Foil is a 5 layer laminate which carries the SANS 1381-4 mark Category C.

It has been used extensively as an insulation membrane under tiled roofs. The aluminium foil

layers provide insulation, the top layer through reflectivity and the bottom layer through its low

emissivity. There must be an air space of at least 50mm for the reflective surfaces to function

efficiently. The product does not need to be scrim reinforced as the spunbond layer provides

adequate strength and stability.

The product will also act as a dustproof layer when used under roof tiles and has

excellent vapour resistance.
