Introduction to Sprayed Polyurethane Foams

SRAY-APPLIED POLYURETHANE foam is a unique roofing material. It is sprayed as a liquid directly onto the roofing substrate; within seconds it foams, expanding 20 to 30 times its original volume. The foam forms a fully adhered, closed cell structure that resists water infiltration while providing insulation

5 common thermal insulation materials

Mineral wool (0.031-0.045 W/mK) offers good insulation and soundproofing but absorbs water. Fiberglass is cost-effective and non-combustible but can irritate lungs. Polystyrene foam (0.030-0.045 W/mK) is great for foundations but sensitive to solvents. Polyurethane foam (as low as 0.020 W/mK) provides excellent insulation and is easy to apply. Cellulose fibers (0.039 W/mK) are good for insulation and soundproofing but need ventilation. For details, contact Imen Polymer Chemie Co.
