Product Overview<\/b><\/strong><\/h5>\n

The STRUXSYSTEMS XPS Grooved Underfloor Heating Insulation Board is designed for water-based underfloor heating systems. Made from extruded polystyrene (XPS) foam, the board combines thermal insulation with pre-formed grooves for heating pipe installation.<\/p>\n

The grooves are designed to accommodate 16 mm heating pipes at 150 mm center-to-center spacing, helping maintain consistent pipe positioning and support an organized installation layout.<\/p>\n

With a compressive strength of 300 kPa, the board provides a lightweight insulation layer that helps reduce downward heat loss and improve the thermal efficiency of underfloor heating systems.<\/p>\n

Key Features & Benefits<\/b><\/strong><\/h5>\n
    \n
  • Thermal Insulation:\u00a0Helps reduce heat loss into the underlying floor structure and directs more heat upward.<\/li>\n
  • Pre-Formed Pipe Grooves:\u00a0Designed for 16 mm water heating pipes with 150 mm spacing.<\/li>\n
  • Compressive Strength:\u00a0300 kPa for reliable performance under suitable floor system conditions.<\/li>\n
  • Lightweight & Easy to Handle:\u00a0Convenient to cut, position and install on site.<\/li>\n
  • Consistent Pipe Layout:\u00a0Grooves help maintain the intended pipe spacing during installation.<\/li>\n
  • Versatile Applications:\u00a0Suitable for underfloor heating assemblies beneath tile and other compatible floor finishes, subject to the specified system build-up.<\/li>\n<\/ul>\n

    Applications<\/b><\/strong><\/h5>\n
      \n
    • Underfloor heating systems in residential buildings<\/span><\/li>\n
    • New-build and renovation projects<\/li>\n
    • Heating installations beneath tiled floors<\/li>\n
    • Suitable floor assemblies with compatible laminate or engineered wood finishes, subject to flooring system requirements<\/li>\n<\/ul>\n
      Installation Notes<\/b><\/strong><\/h5>\n
        \n
      1. Ensure the substrate is clean, stable and level before installation.<\/span><\/li>\n
      2. Position the boards with the grooved surface facing upward.<\/span><\/li>\n
      3. Fit the 16 mm heating pipes into the pre-formed grooves according to the heating layout.<\/span><\/li>\n
      4. Complete the required load-distribution, screed or overlay layers in accordance with the heating system design and the final floor finish manufacturer’s instructions.<\/span><\/li>\n<\/ol>\n

        Important:<\/strong>\u00a0The 300 kPa compressive strength of the XPS board alone does not establish the load capacity of the complete floor assembly. Direct tile installation or installation without a screed should only be used where the complete system has been specifically designed and approved for that application.<\/span><\/p>\n
