The PUR IZOLACE SOFT thermal insulation system is a light, two-component, machine-processed water based polyurethane foam with a predominantly open cell structure, while the foam itself is created with CO2 and steam. The PUR IZOLACE SOFT system is the Czech alternative of the Canadian and American systems with an improved thermal conductivity coefficient (λ = 0.035). It provides excellent vapour permeability and has very good sound insulation parameters (sound transmission loss). The foam is self-extinguishing.
