Durafoil Ultra Single Foil

Available in store

Durafoil Ultra Single Foil has been developed specifically for use under roof tiles and is certified under SANS 1381-4 Class D. The aluminium foil later will not radiate or emit heat downwards and the product is applied with the aluminium surface facing down towards the interior of the building. The spunbond membrane gives the product substantial strength and stability.

Durafoil Ultra Single foil does not have foil on the section of the membrane which acts as the overlap; this reduces the cost of the membrane as the section where the membrane overlaps the layer underneath makes the foil surface ineffective as it needs an airspace to function as an insulator.

Other than insulate the roof space the membrane will reduce draughts and dust penetration into the roof area. The membrane is also designed to prevent moisture from damp air from condensing on the ceiling boards and other vulnerable points in the building fabric.

Most home loan institutions insist on the use of an under-tile membrane where the roof pitch is less than 26 degrees or more than 45 degrees and also in exposed coastal areas as the membrane will prevent strong winds from ripping off roof tiles.
