Why XPS Backer Board

Engineered for demanding construction environments

💧

Waterproof

Closed-cell structure with <0.3% water absorption. Ideal for wet areas, shower bases, and exterior applications.

🪶

Lightweight

At 28–45 kg/m³ density, XPS boards are easy to transport, handle, and install — reducing labor cost.

✂️

Easy to Cut

Score and snap with a utility knife. No dust, no special tools. Clean edges every time.

🔥

Thermal Insulation

Low thermal conductivity (0.028–0.034 W/m·K) provides excellent insulation for walls and floors.

💪

High Compressive Strength

150–700 kPa range to meet different load-bearing requirements, from residential to commercial.

📐

Custom Sizes

Available in thicknesses from 4mm to 20mm, custom dimensions and surface finishes on request.
