Designed Specifically for Wet Underfloor Heating Systems
Wet underfloor heating systems use water pipes embedded in concrete. The concrete layer can be heavy. The insulation board underneath must handle that weight without deforming. Ordinary foam boards often fail under such pressure. That is why we developed our thermal insulation boards for underfloor heating. These boards have a higher density than standard XPS. They do not compress under the weight of wet concrete and floor finishes. They also have very low thermal conductivity, so heat goes only where you want it: upward into your room. We have 23 years of experience making XPS. We were the first company in southern Zhejiang to produce extruded polystyrene. Our production lines include CO2 foaming technology, which gives our boards a uniform closed-cell structure. This structure is what makes our thermal insulation boards for underfloor heating so effective.

These thermal insulation boards for underfloor heating have been supplied to projects like Wenzhou MixC and several high-end residential complexes. They meet the requirements of both residential and commercial floor heating systems.
Long-Term Reliability and Easy Ordering
Once installed, these boards will not lose their shape or insulating properties over time. We test every batch for compressive strength and thermal conductivity. We also offer OEM and ODM services. Do you want your own brand on the boards? We can do that. MOQ is flexible. For large volume orders, we provide tiered discounts. Payment terms: 30% deposit, 70% balance before shipment. We accept USD and CNY. We also send production photos and videos so you can track your order. One-year warranty covers non-human damage. Transport damage? Send us photos, and we will replace the boards. Choose our thermal insulation boards for underfloor heating for professional-grade performance and peace of mind.
