Extruded Polystyrene, often abbreviated as XPS, is a type of rigid foam insulation made from polystyrene resin. It is produced through an extrusion process, which creates a closed-cell structure that provides excellent thermal insulation. XPS is commonly used in construction for insulating walls, roofs, and foundations due to its durability and moisture resistance. This material is lightweight and easy to handle, making it a popular choice for builders and contractors. Additionally, Extruded Polystyrene is available in various thicknesses and sizes, allowing for flexibility in different applications. Its energy efficiency contributes to reducing heating and cooling costs in buildings.
