Chema EPS
CHEMA EPS is a versatile expanded polystyrene (EPS) foam board designed for multiple construction applications. It serves as a high-performance solution for thermal and acoustic insulation, a flexible filler for expansion joints, and is ideal for void filling and wall thermal insulation. A primary benefit of using CHEMA WHITE FOAM is its significant impact on energy efficiency, enabling electricity power savings of up to 40%. The material is exceptionally light weight, which makes it easy to handle during both transportation and on-site installation. By providing excellent thermal insulation, it reduces overall electricity consumption and allows for the use of lower wattage air conditioning systems.
