Breeze Block Airtight PU Foam

Airtight expanding PU foam.

A fast setting, 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. Bonds, fills, seals and insulates most construction materials.

Features & Benefits: Near-zero curing pressure and low post expansion avoids deformation of building elements. - High thermal insulation value. - Gives an airtight seal: <0.1m3 / [h.m(daPa)2/3] according to EN 12114:2000. - B2 Rating according to DIN 4102-1. - Sub-zero formula - can be used at temperatures as low as -5oC. - 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.
