Polyurethane Rigid Foam
The polyurethane rigid foam used in Mekpan Panel brand sandwich panels stands out with its high thermal insulation capacity. Supplied from the world's leading manufacturers, this material offers particularly long-lasting insulation solutions thanks to its water-repellent structure and insect-proof feature. Polyurethane rigid foam provides energy efficiency and minimizes heat loss in buildings thanks to its low thermal conductivity coefficient. These features make it an ideal insulation material for both industrial and commercial structures.
Polyurethane draws attention with its closed cell structure. Thanks to this closed cell ratio, water and vapor impermeability is increased. At the same time, polyurethane foam, which offers dimensional stability, maintains its form even with temperature changes and thus provides long-term durability. It shows maximum performance at temperatures between -200°C and 110°C. Polyurethane foam's high compressive strength and low water absorption make structures stronger and more reliable.
