Alucushion® / Bubblefoil® FR (Fire retardant grade) is manufactured by a continuous lamination process of low density polyethylene and aluminium foil with sealed bubbles of air between the two outer laminates. The thousands of individually celled air bubbles created during the manufacturing process, form a column of immobilised dry air, effectively countering heat loss through convection and conduction. Add to this the low emissivity and high reflectivity of the aluminium foil surface, and it's advantages as a heat transfer barrier become obvious.
Alucushion® / Bubblefoil® FR (fire retardant grade) is the cost effective solution for most roof insulation applications.
Benefits
Strong, light and flexible with excellent tear resistance
Heat stabilized for durability and effective in a temperature range from -20C° to 80°C.
Non-toxic, inert and vermin proof
Waterproof - no membrane necessary under roof tiles or sheeting
Aesthetically pleasing finish with good light reflectance
Acknowledged by the trade as the easiest thermal insulation on the market to install
Alucushion® FR is tested and evaluated according to SABS 1381 (Materials for Thermal Insulation of Buildings) Part 4: Reflective Foil laminates, rolls, sheets and sections.
Fire Performance
Alucushion® / Bubblefoil®FR (fire retardant grade) has been tested by Firelab and found not to cause fire to spread when used as an over-purlin type roof insulation material. The product contains a highly advanced fire retardant, and is tested to the SANS 428 standard (Fire testing of building insulation materials, components and elements used for roofs) as part of SANS 10400 Part T of the National Building Regulations.
