Introduction to 120mm EPS Wall Panels

120mm EPS (Expanded Polystyrene) wall panels are a popular building material known for their excellent insulation properties, lightweight nature, and ease of installation. EPS is a rigid, closed - cell foam plastic made from expanded polystyrene beads. The 120mm thickness provides a good balance between insulation efficiency and structural integrity. These panels are widely used in both residential and commercial construction projects, helping to reduce energy consumption by preventing heat transfer through the walls. They also offer sound insulation benefits, contributing to a more comfortable indoor environment. Additionally, their lightweight design makes them easier to handle and transport, reducing labor and shipping costs.
