Alucushion Bubblefoil Benefits
- Strong, Light, and Flexible: Excellent tear resistance ensures durability and ease of handling.
- Heat Stabilized: Effective in a temperature range from -20°C to 80°C, ensuring long-term performance.
- Non-Toxic and Inert: Safe for use as insulation for ceilings, and vermin proof.
- Waterproof: No additional membrane is necessary under roof tiles or sheeting.
- Aesthetically Pleasing: Offers a good light reflectance and a clean finish.
- Easy to Install: Recognized by the trade as the easiest thermal insulation to install on the market.
- Certified Performance: 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 rigorously tested by Firelab and confirmed not to propagate fire when used as an over-purlin type roof insulation material. It features a highly advanced fire retardant and complies with 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.
- Alucushion®/Bubblefoil® FR White: B/B1/2/H only (SP & USP)
- Alucushion®/Bubblefoil® FR Double-sided: B/B1/2/H only (SP)
