Insultherm Extruded Polystyrene (XPS) Insulation Boards

Insultherm Extruded Polystyrene (XPS) insulation is a premium rigid foam board engineered to deliver consistent thermal performance and long-term durability in demanding construction environments. Manufactured using a continuous extrusion process, these boards feature a closed-cell structure that provides exceptional resistance to water absorption and vapor transmission, making them ideal for areas prone to moisture or where structural integrity is critical.

The uniform cellular makeup of Insultherm XPS ensures high compressive strength, allowing it to withstand heavy loads without deformation. This makes it an excellent choice for roof insulation, under-slab foundations, and wall systems where both thermal efficiency and mechanical support are required. The material is non-combustible in terms of structural degradation over time and maintains its insulating properties throughout the building's lifecycle.

Key Applications and Benefits

• Roof and Ceiling Insulation: Provides a continuous thermal barrier to reduce heat gain and loss, enhancing energy efficiency.
• Wall and Cavity Wall Systems: Suitable for external wall insulation (EWI) and internal applications, improving thermal mass and preventing condensation.
• Waterproofing and Damp Proofing: The low water absorption rate protects underlying structures from moisture damage, ideal for basements and wet areas.
• Structural Stability: High compressive strength supports heavy loads in floors, roofs, and foundations without settling or crushing.
• Dimensional Stability: Maintains shape and size over time, ensuring a tight fit and reducing thermal bridging.
