Extruded Polystyrene

Extruded Polystyrene (XPS) is a high-performance rigid foam insulation material that provides excellent thermal resistance, moisture resistance, and compressive strength. Consequently, it is widely used in building insulation, roofing, and flooring applications.

Both XPS and EPS are polystyrene-based insulation materials; however, there are key differences: 

• XPS (Extruded Polystyrene): Has a closed-cell structure, making it stronger, more moisture-resistant, and thermally efficient. 
• EPS (Expanded Polystyrene): Has an open-cell structure, making it more breathable but less resistant to water absorption and compression. 

As a result, XPS is preferred for underground, wet, or high-load applications.

ibeam’s high-quality Extruded Polystyrene (XPS) is ideal for: 

• Roof insulation – Reduces heat transfer and improves energy efficiency. 
• Wall insulation – Provides superior thermal protection for buildings. 
• Floor insulation – Enhances underfloor heating and prevents heat loss. 
• Basement and foundation insulation – Protects against moisture and soil pressure. 
• Cold storage insulation – Maintains stable temperatures in refrigeration systems. 

Using XPS insulation provides several advantages: 

• Superior thermal insulation – Reduces energy costs by preventing heat loss. 
• High moisture resistance – Prevents mold and water damage. 
• Excellent compressive strength – Ideal for load-bearing applications. 
• Durable and long-lasting – Retains its insulating properties over time. 
• Environmentally friendly – Many XPS products are made with sustainable materials. 

Since XPS has a high R-value (thermal resistance), it minimizes heat transfer, keeping interiors cool in summer and warm in winter. Consequently, it reduces HVAC energy consumption and lowers electricity bills.

Yes, ibeam’s Extruded Polystyrene (XPS) has a closed-cell structure, making it highly resistant to water absorption. Therefore, it is ideal for use in basements, foundations, and moisture-prone areas.

We provide XPS insulation in various thicknesses and densities, depending on your project needs. Contact us for custom sizing options and bulk orders.

XPS can be installed using: 

• Mechanical fastening – Screws or anchors to secure it to walls or floors. 
• Adhesive bonding – Using construction-grade adhesives. 
• Foam insulation boards – Can be easily cut and fitted into any space.

Additionally, always follow building regulations and manufacturer guidelines for the best results.

While XPS provides good insulation, it is combustible. Therefore, it should be used with fire-rated coatings or integrated into fire-resistant wall systems for safety compliance.
