PolyFoam XPS Polyfoam UFH Board - 1200mm x 600mm

• Manufactured to close thickness tolerance avoiding any unnecessary steps in installation
• Robust and can tolerate foot traffic from following trades
• Lightweight, easy to handle

Polyfoam UFH Board is best suited for use in underfloor heating systems where a stable and thermally efficient base is required to house heating pipework. Designed to provide a reliable carrier for proprietary underfloor heating components, these boards securely hold PERT pipes in place with dedicated panels for both end returns and straight infills, ensuring consistent pipe alignment and ease of installation. The system delivers excellent thermal performance by minimising heat loss and promoting even heat distribution across the floor surface. Floor covering suitability should always be confirmed with the manufacturer to ensure compatibility with the specific application. Polyfoam UFH Board offers a practical, high-performance solution for integrating underfloor heating into new-build or retrofit projects.

What applications is it suitable for?

• Under-floor heating systems in ground floor slabs (below or above screed) where the insulation board serves both as insulation and as a board to carrier pipework
• Floating floor systems above slab with UFH embedded.
• Retrofit or new build floors where under-floor heating is specified and minimal board thickness or quick installation is required.

What are the benefits of using UFH Board versus generic insulation boards?

• It is specifically tailored for UFH: routed channels simplify pipe layout and secure fixing of the pipework.
• The high compressive strength and moisture resistance ensure it can support screeds or floor finishes above without degradation.
• Good thermal performance (low λ-value) helps maintain efficient heating response.
• Lightweight and easy to handle on site, reducing labour

Are there any limitations or things to watch?

• Although compressive strength is reasonably high for the thicknesses listed, designers must still verify loadings (screed, finishes, loads from furniture) and deflection or serviceability requirements.
• Fire performance: The listed fire reaction classification is F (Euroclass F) for this board.This means additional fire protection or detailing may be required depending on the project specification.
• The board’s thickness (e.g., 18mm, 24mm) may impose limitations on the depth of screed or floor finish; designers must check the total floor build-up.
• The board should not be left exposed to prolonged UV or open flame; handle and store per manufacturer’s guidance.
• Floor finishes need to be compatible with the UFH system and the insulation board’s properties.
