Product Description

XPS Rigid Extruded Polystyrene Foam Sheet

XPS Foam Board is fabricated mainly from polystyrene resin with a small amount of additives through a specialized extrusion process. During extrusion, polystyrene particles are shaped into a continuous closed-cell foam structure under high temperature and pressure.

Low thermal conductivity (≤0.035 W/(m·K))
High compressive strength (more than 1.2MPa)
Fire-protection rating B1
Lightweight and easy to install

Frequently Asked Questions

What is XPS foam board used for?

XPS (Extruded Polystyrene) foam board is primarily used for thermal insulation in walls, roofs, floors, and cold storage, as well as lightweight filler for civil engineering projects like roads and bridges.

What is the fire rating of this material?

Our XPS foam board achieves a Class B1 fire-protection rating, meaning it has excellent flame-retardant properties suitable for building safety standards.

Is the material water-resistant?

Yes, it has a high hydrophobicity rating of ≥98%. The closed-cell structure effectively prevents water absorption, maintaining its insulation performance in damp environments.

Can I request a specific surface finish?

Absolutely. We offer various surface treatments including planed, fluted, and embossed finishes to meet different adhesion and application requirements.

What are the main advantages of XPS over other insulation?

XPS offers a combination of very low thermal conductivity and exceptionally high compressive strength (up to 1.2MPa or more), making it durable under heavy loads while providing superior energy efficiency.

How should the boards be stored?

For optimal preservation, XPS boards should be stored indoors or under a waterproof covering to protect them from prolonged UV exposure and extreme weather.
