Extruded polystyrene is a rigid, closed-cell foam insulation material widely used in construction for its superior thermal insulation properties. Manufactured through a continuous extrusion process, XPS has a uniform structure that provides excellent moisture resistance, compressive strength, and long-term durability.
It is lightweight, simple to handle, and resistant to environmental factors such as water, mould, and temperature fluctuations. XPS is commonly available in various thicknesses and densities to suit diverse insulation needs in residential, commercial, and industrial projects.
Areas of Application: Extruded Polystyrene
- Extruded Polystyrene serves as insulation for both roofs and walls in buildings.
- This material is used in below-grade areas, such as foundations and basements.
- It also serves as insulation for floors, cold storage areas, and industrial facilities.
- Used in road and railway construction for frost protection.
- It serves as a lightweight filling material in various construction projects.
Advantages of extruded polystyrene:
- Outstanding thermal performance.
- High compressive strength for structural support.
- It exhibits resistance to moisture, thereby preventing the growth of mould and rot.
- Long-lasting and recyclable.
- Easy to cut and install.
Density: Typically ranges from 28 kg/m³ to 50 kg/m³, depending on the application and manufacturer. Higher-density boards are used for applications requiring greater compressive strength.
Thickness: Commonly available in thicknesses ranging from 20 mm to 100 mm.
