Closed-cell

Applied by spraying using specialised machines, these rigid closed-cell two-component polyurethane foams are used as thermal insulation for buildings. Characterised by excellent insulating properties and low specific weight while maintaining good mechanical properties, they are used as internal and external insulation for buildings.

Closed-cell polyurethane spray foam systems — declared properties according to EN 14315-1
