Foil insulation

• Durafoil Insububble

  

  Durafoil Insububble is a four layer laminate which utilizes:
  1. The foil layer for reflective isulation
  2. A laminating layer
  3. The spunbond layer for stability, strength and thermal isulation and
  4. The polyethylene bubble layer for additional insulation.
  
  The product is aesthetically pleasing and attractive when
  applied under metal roofs. Insububble can be used under
  domestic or industrial roofs. It is flame retardant and carries the SANS 1381-4 mark Class E. Tested in terms of SANS 10177 the product has been classified as class B/BI/2/H which means it has a superior flame retardancy and can be used in any structure with a B1 rating with sprinklers.
  The product has been tested with sprinklers. Insububble has a strong tear resistance and will not expand when in contact with changing roof temperatures as in the case with other bubble type insulation membranes which consist mainly of polyethylene layers.
  
  Insububble is dimensionally stable and easy to work with.

• Durafoil Ultra Double Foil

  

  Durafoil Ultra Double Foil is a 5 layer laminate which carries the SANS 1381-4 mark Class C. It has been used xtensively as an insulation membrane under tiled and metal roofs. The aluminium foil layers provide insulation, the top layer through reflectivity and the bottom layer through its low
  emmisivity. 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.

• Durafoil Ultra Single Foil

  

  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 layer 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 roofspace 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.

• Durofoil Industrial DSD

  

  Durafoil DSD is a 6 layer laminate consisting of two outer layers of aluminium foil, one layer of spunbond, one layer of reinforcing scrim and two layers of laminating polyethylene.
  It is a top of the range product and carries the SANS 1381-4 Class A mark certification.
  
  The reinforcing scrim provides additional strength and stability making the product ideal for industrial applications.
  
  Durafoil DSD has a B/B1/2/H fire rating which means it has a superior fire resistance and can be used in any structure with a B1 fire rating with sprinklers.
