Extruded polystyrene insulation board - 5 mm thick, 300 kPa - pack of 27.0 m² HD-XPS300/36

Underlayment for panels and boards – comfort and protection for your floor

This high-quality underlayment made of extruded polystyrene (XPS) is an ideal solution for anyone who prioritizes the thermal and acoustic comfort of their floor. Made of HD-XPS300 material with a thickness of 5 mm, it provides effective thermal and mechanical insulation, protecting against cold and moisture. This is particularly important when installing floating floors, such as laminate panels, engineered wood flooring, or SPC vinyl panels.

Properties and application

The underlayment is characterized by exceptional compressive strength – as much as 300 kPa. This means it perfectly handles loads, levels out minor irregularities in the substrate, and prevents the formation of unpleasant sounds during floor use. Therefore, it is reliable both in new construction and during renovations. Its application translates into improved heating efficiency – heat remains in the room, and operating costs are reduced.

This underlayment is also recommended for use with Heat Decor underfloor heating systems (HD-G, HD-EPL or HD-PRO foils), where it effectively directs heat towards the room. The ability to precisely cut holes for heating cables simplifies installation and ensures an aesthetic appearance. In addition, the material is moisture-resistant and biologically inert, guaranteeing long-term protection against dampness and mold growth.

Key advantages:

• High strength: 300 kPa ensures stability and resistance to loads.
• Excellent thermal insulation: reduces heat loss and lowers heating costs.
• Noise reduction: eliminates impact noise and improves acoustic comfort.
• Moisture resistance: protects against dampness and mold growth.
• Compatibility with underfloor heating: ideal for Heat Decor systems and low-temperature surface systems.
• Easy installation: possibility of precise cutting and making holes for cables.
• Durability: resistant to biological factors – does not rot or mold.
