Introduction to EPS Insulation Panels

Expanded Polystyrene (EPS) insulation panels are a popular choice in the construction industry for their excellent thermal insulation properties, lightweight nature, and cost - effectiveness. EPS is made from small beads of polystyrene that are expanded and fused together to form a rigid panel. These panels are widely used in both residential and commercial buildings to reduce heat transfer, lower energy consumption, and improve indoor comfort. They can be used in various applications such as wall insulation, roof insulation, and floor insulation.
