Insulation with polyurethane foam
Flexibility. Polyurethane foam is suitable for the majority of finished tubs and significantly improves thermal insulation properties of structure walls and bottom.
Reliability. Polyurethane foam is sprayed on the curved surface without seams and joints, which means that cold joints are impossible. Polyurethane foam is keys well to polymer bases. It serves as waterproofing layer and is not deformed.
Safety. Polyurethane foam doesn't sustain flame combustion and goes out without an open-flame source.
