Reflector 400 kPa

XPS insulation board for electric underfloor heating

• Compressive strength of 400 kPa
• Only 6 mm thick
• Thermal conductivity 0.038 W/m*K
• Closed-cell XPS with low water absorption
• Can help reduce floor noise and walking noise
• Cuts easily with a knife

 
Reflector 400 kPa is a high-density XPS insulation board designed for electrical underfloor heating systems. It reduces downward heat loss, improves heating efficiency, and provides a strong, stable base for floating floor constructions.

At only 6 mm thickness, the board adds effective insulation while maintaining a low overall floor build-up. The closed-cell XPS structure provides low water absorption, maintaining reliable insulation performance in humid conditions.
