Soudal Gun Grade SWS Flexible Window & Door Foam 750ml

Unlike traditional expanding foams which become rigid when fully cured, SWS foam remains flexible and is able to accommodate any expansion or contraction of the substrate or frame without tearing or cracking. 

As the integrity of the foam structure remains intact regardless of material movement, acoustic and thermal properties of the foam are maintained and exceed that of traditional expanding foams. 

The low foaming nature of the product gives maximum control during application reducing waste and clean up.
