Breeze Block Airtight PU Foam

SKU BDBB750

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.

B2 Rating according to DIN 4102-1.

Non‐shrinking.

Accoustic dampening - up to 63dB.

APPLICATION
