Breeze Block Airtight PU Foam
A multi‐purpose, gun grade polyurethane foam ideal for use as an air tight gap-filler for general construction joints where movement is likely. Absorbs component movement thereby giving an air-tight seal to reduce heat loss and improve energy efficiency in buildings.
Features & Benefits: Airtight sealing (independently tested by Rossenheim Labs) <0.1m3 / [h.m(daPa)2/3] according to EN 12114:2000. - All-season use: application temp -5oC to +30oC. - Zero curing pressure <0.7 Kpa & low post expansion. - Avoids deformation of building elements. - Permanently elastic foam: ideal for sealing joints subject to movement or pressure sensitive applications. - High thermal and sound properties. - Tensile Strength > 55 Kpa. - Elongation 20% - Fast setting. - Yield per 750ml = 45 Litres.- Non‐shrinking. - Acoustic dampening - up to 63dB.
Uses: Bonds, fills, seals and insulates most construction materials, which has a reaction to fire rating of class B2 (DIN4102:1). The fresh foam adheres to wood, concrete, block, stone, plaster, metal, PVC and polystyrene.
Areas of Application: - Installation of window and door frames and entrance door linings - Filling of holes. - Insulation of penetrations. - Sealing of thermal and acoustic insulation boards. - Sealing and connection of joints. - Reducing the impact of thermal bridges.
Conforms to: B2 Rating according to DIN 4102-1.
