Open-cell
Applied by spraying using specialised machines, these semi-rigid open-cell two-component polyurethane foams are used as thermal and acoustic insulation for buildings. Characterised by very low specific weight and featuring good insulating properties, high vapour permeability and resistance to fungi and mould, they form a tight layer of insulation, eliminating thermal bridges. They are used mainly as internal insulation for walls and attics.
