Polyurethane Spray foam

PUR foam is sprayed in a liquid form, and due to the excellent adhesive properties it penetrates into the structure of the material on which it is sprayed (wood, concrete, breathable film) joining them permanently. A few seconds after spraying the foams expands its volume 120 times in the case of the open-cell foam, and 35 times in the case of the closed-cell foam, filling all, even the hardest to reach areas. Thanks to that the PUR foam is connected to the entire surface of the roof or for eg. of the attic, thus it eliminates completely the thermal bridges appearing while using other technologies.
