XPS Insulation – 300kPa – Residential & Commercial

Product Overview

Experience superior insulation with our 100mm thick, high-compressive strength XPS Extruded Polystyrene Boards. Designed for extreme durability, these rigid, closed-cell boards offer exceptional thermal insulation for floors, basements, and inverted roofs.

With a dense cellular structure, these boards maintain their mechanical strength and thermal integrity under concrete, paving, or ballast, even in harsh conditions. They resist water absorption, vapour transmission, and freeze/thaw cycles, ensuring consistent performance.

Features & Benefits

• High Compressive Strength: Withstands 300kPa loads, perfect for heavy-duty applications.
• Closed-Cell Structure: Prevents water ingress, maintaining insulation even in damp environments.
• Reliable Thermal Performance: Thermal conductivity of 0.034 W/m·K for enhanced energy efficiency.
• Durable & Lightweight: Easy to handle, cut, and shape without compromising strength or performance.
• Moisture Resistant: Retains stability and performance when exposed to wet conditions.
• Sustainable: Manufactured with zero ozone depletion potential and low global warming potential.

Applications

• Ground Floors: Provides a robust insulation layer under screed or slab floors.
• Inverted Roofs: Ideal for thermal protection above waterproof membranes.
• Foundations & Perimeters: Offers essential compressive strength and moisture resistance.

Installation Guidance

• Substrate Preparation: Ensure surfaces are level, clean, and free from water.
• Cutting: Use a fine-toothed saw or score and snap for precise joints.
• Fixing: Apply in a staggered bond with suitable adhesives or mechanical fixings.
• Protection: Shield from UV exposure and site traffic until covered.
• Storage: Store flat, protected from sunlight.

Our XPS insulation boards are crafted for long-term performance and sustainability, meeting rigorous industry standards.

FAQ
