GNS Premium Foam Winter PU-foam with straw applicator for winter use construction foam
GNS Premium Foam Winter PU-foam with straw applicator for winter use construction foam is a one-component, self-expanding, ready-to-use, Multi-purpose Polyurethane Foam. The foam will expand and cure by moisture in the air. It is used for a wide range of building applications. It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation. It is special designed for applications at temperature as low as -18ºC.
