The PUR IZOLACE W40 thermal insulation system (bulk density 40 +/- 5 kg/m3) is a two-component polyurethane foam with a predominantly closed cell structure. The process is performed by high-pressure spraying on the underlying surface, which can be formed with e.g. sheet steel or non-ferrous metals, concrete, fibre cement, oriented strand and plaster boards, laminate, foils and fabrics or a number of other materials. 

This insulation system is intended for the insulation of attics, ceilings, walls and a number of horizontal, vertical or slanted roofs or roofs of various shapes. Thermal conductivity coefficient (λ = 0.026 W/m.K). The values decrease with increasing thickness.
