Xfoil | Thin Foil Insulation with Vapour Control

XFOIL BROCHURE

The Xfoil™ Range seals your roof against climactic elements like wind and damp while at the same time retaining ventilation. Using reflective technology Xfoil™ is clean, does not cause allergies, does not cause dust and contains no toxic products.

How Does Xfoil™ Work?
The Xfoil™ Range is constructed from numerous layers of high strength polyester, reinforced metallised polyester film and also polyester wadding. Xfoil™ offers you a sustainable product that insulates your roof and helps with acoustic performances.

Xfoil™ As A Vapour Barrier
Xfoil™ has been tested to BS EN 12086: 1997, Determination of Water Vapour Transmission Properties. The test confirmed an extremely high vapour resistance. Xfoil™ is one of the few insulating materials that is not affected by humidity and consequently its insulating values remain unchanged from the bone-dry state to very high humidity conditions. When installing Xfoil™, it acts as an insulant and vapour control layer in one.

When the joints of Xfoil™ where tested to Moat 27, Test 5.2.1: Test resistance to leakage at joints. Air pressure at 10KPa maintained on a taped 25mm lap joint for a 30 minute duration. No leakage observed on all three samples.

Test Method
Test
Test Resistance to Leakage at Joints. Test Method: Moat 27, Test 5.2.1.

Conclusion
Air pressure at 10kPa maintained on a taped 25mm lap joint for a 30 minute duration. No Leakage observed on all three samples.

Test
Tensile Strength – shear at joints. Test Method: Moat 27, Test 5.2.2.

Conclusion

Failure Mode
No failure occurred at the taped lap joints. All samples failed, cohesively in the outer layer of the product. The foil tears first, then out, with the plastic backing continuously elongating.

Test
Test for resistance to tearing. Test Method: Moat 27, Test 27, Test 5.4.1.

Conclusion
