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.The RSF range is the same as the RSM but with a foiled reinforced covering which is water-resistant. Certifications:– Tested to BS EN 1363-1 (1999), achieving up to 132 minutes protection.– Tested to BS476 Part 20, achieving up to 66 minutes protection.

ENVIROGRAF FFCB Rainscreen Fast Fix Cavity Barrier - (40mm airflow) - ALL SIZES

Rainscreen fast fix ventilated cavity barrier, an effective solution for ventilated rainscreen cavities. Suitable for both horizontal and vertical application. Supplied in 1220mm lengths with 4 fixing brackets per length. In addition, achieves 2 hours of fire protection for cavities from 75mm to 315mm.Mechanically fix the cavity barrier to the substrate at maximum 500mm centres with non-combustible fixings. Ensure there are no gaps between the substrate and the barrier when attached to the wall.Cavity Barriers are pieces of fire-stopping material. They fit within the cavity of a building at each floor horizontally and party wall in a vertical position. The material provides compartmentation. Both the flames and heat cannot be transferred to other compartmental areas. Throughout the life of the building, the Cavity Barrier will remain fixed in place. In the event of a fire, the intumescent material expands and seals off the gaps. Additionally, the horizontal barriers allow for a ventilation gap within the cavity. Subsequently closing when the intumescent expands. Certifications:– Fire test performance according to the BS EN 1363-1:1999, achieving 2 hours fire protection.

ENVIROGRAF Flexible Strip Cavity Barrier (with brackets) - 2m x 30mm

ENVIROGRAF Flexible Strip Cavity Barrier is a flexible, PVC and foil-clad intumescent strip with self-adhesive backing to adhere to walls. Designed especially for timber frame buildings. High expansion intumescent locks against the external side of the internal wall in a fire without affecting outer wall. Blue plastic sleeve robust enough to prevent damage by water or pests. Under heat the intumescent creates a fire seal, thus providing full fire protection. Certification: Strip barrier tested to BS476 parts 20, 22 and BS EN 1363-1 (1999), giving fire protection from 60 to 120 minutes.
