ENVIROGRAF Flexible Sponge Rainscreen Cavity Barrier (RSF) - ALL SIZES
Flexible sponge rainscreen moisture resistant cavity barrier range, especially designed to offer excellent passive fire protection for rainscreen and other types of cladding. Using fireproof sponge instead of mineral wool, this range offers many advantages:
- The barrier is much thinner, additionally offering a better fire rating.
- Easy to fix and no masks required.
- Fixing brackets already in place, fix with screws, nails, or spit nails.
Made in 1-metre lengths, with 4 fitting brackets for horizontal application or 3 brackets for vertical. Cut with a sharp knife to fit around metalwork. The cover is made from a strong, intumescent-coated material, completely water-resistant.
