Engineering Excellence & Product Overview
XPS 500 Underfloor Heating Overlay Boards are high-compressive grooved XPS panels engineered for dry-fit underfloor heating retrofits and new overlay builds. Boasting 500kPa compressive strength, closed-cell water-resistant structure and integrated heat-spreading foil, these overlay boards deliver stable thermal performance while keeping minimal build-up height. Pre-routed pipe grooves simplify neat pipe laying, compatible with a wide range of final floor finishes including tiles, vinyl and engineered wood. Ideal for renovation projects where screed pouring is not feasible, available for bulk B2B orders with full test documentation upon request.

Quality Assurance & Test Reports
- Standardised Performance Testing: The XPS 500 overlay boards are assessed by accredited labs for core metrics including compression resistance, thermal behaviour and moisture resistance to meet European construction norms.
- Multi-stage In-house QC Gates: Checks run from incoming foam pellets, hot-press lamination to finished grooved panel dimension control; defective goods are segregated before shipment.
- Customised Test Support: We can prepare targeted test summaries and technical documentation to match your local building authority or contractor requirements.
- Shipment Pre-loading Audit: Random spot checks are carried out prior to container loading to verify visual quality, thickness and groove consistency against the approved test sample.
Application Range
- Domestic Refurbishment Jobs: Preferred grooved XPS overlay boards for home heating upgrades, especially for old properties that cannot accommodate wet screed construction.
- Light Commercial Heating Schemes: Adapted for salons, small clinics and coworking areas, its 500kPa strength handles regular pedestrian loading safely.
- Multi-Finish Floor Configurations: Compatible with ceramic tiles, LVT, vinyl and floating wood flooring over water-based underfloor heating circuits.
- New-Build Dry Floor Zones: Applied in new constructions where fast-track installation is required, cutting curing time compared with traditional screed heating setups.
