Keep Heat Inside Your Room, Not Under the Floor
Have you ever walked on a floor that feels cold even when the heating is on? That often happens because the insulation layer underneath is missing or poor. Heat goes sideways or downward instead of rising to your feet. Our floor heat insulation board solves this problem. It is a rigid XPS board placed directly under the heating pipes or electric mats. Its job is simple: block heat from going down. As a result, your floor surface reaches the desired temperature faster, and your heating system cycles less often. That saves energy and extends the life of your heating equipment. We started making XPS in 2003. We are the first XPS factory in southern Zhejiang. Our facility covers 15,000 square meters, and our monthly output is 50,000 cubic meters. We have ISO 9001 and ISO 14001 certification. Every floor heat insulation board we ship is tested for flatness, compressive strength, and thermal performance.
Performance Data That Matters for Floor Heating
For floor heating applications, compressive strength and thermal conductivity are the two most important factors. Our boards perform well in both areas. See the table below:

Our floor heat insulation board has been used in radiant floor heating systems for both residential homes and commercial buildings. One notable project is the Pingyang Wanda Plaza. The contractor chose our boards because they are easy to cut and install, and they do not crumble under the weight of the screed.
Simple Installation and Cost-Effective Solutions
Installation is straightforward. First, make sure the subfloor is clean and level. Then lay our boards tightly together. For best results, tape the seams with aluminum foil tape. Then lay the reflective film, heating pipes or mats, and finally the screed. No special training is needed. If you are working on a large project, we can mix different thicknesses in one order. For example, use 50 mm boards for ground-floor heating and 20 mm boards for upper floors. Large orders qualify for discounts. We also offer free sample blocks for regular models; you only pay shipping. One-year warranty applies. Choose our floor heat insulation board for a warmer floor and lower heating costs.
