Crossin® Hard 50

Crossin® Hard 50 is a PUR spray foam with increased strength resulting from higher density. Crossin Hard 50 Polyurethane foam provides excellent thermal insulation even at low thicknesses.

Crossin® Hard 50 insulation, apart from one of the lowest heat transfer coefficients (U), it also provides very high insulation against moisture is highly wind resistant.


Izolacja Crossin® Hard 50 insulation is designed for outdoor thermal insulation of large, flat roofs and multi-layer roofs, using spraying method. It is particularly recommended for insulating roofs in industrial, agricultural, commercial and residential buildings (especially in single and multi-family buildings and public buildings).
