Fastwarm™ FastTile+ is a high-compressive strength 200 kPa XPS insulation board specifically engineered for low-profile underfloor heating systems. It features durable cement coatings on both faces, making it ideal for direct tiling or application of floor leveller. Once levelled or tiled, it supports all common floor coverings.
The board measures 1200mm x 600mm x 20mm and comes pre-grooved at 150mm pipe spacing. These grooves are precision-cut to accommodate Fastwarm 16mm underfloor heating pipes, offering an efficient layout with quick, accurate installation and optimal heat output.
- Pre-grooved for pipework – Provides ready-made pipe securing and spacing with 150mm centres for fast, accurate installation.
- High compressive strength – Constructed from XPS with 200 kPa rating, ideal for tiled floors and heavy-use areas.
- Dual-purpose surface – Cement-coated faces allow for direct tiling or levelling, supporting a wide range of floor finishes.
- Panel dimensions – Each board measures 1200mm x 600mm x 20mm, suitable for 16mm underfloor heating pipes.
- Efficient heat output – Delivers up to 76W/m² when used with Fastwarm 16mm pipe, ensuring consistent and responsive heating performance.
This board offers a premium all-in-one solution for solid, low-profile installations, making it ideal for renovation or new build projects where efficiency and durability are key.
- Ensure subfloor that the system is being laid to is structurally sound and ready to accommodate the FastTile+ system.
- Clear floors of dust and debris and prepare the floor using a suitable primer. We recommend Ultra Prime IT MSP
- Allow primer to dry prior to adhering FastTile+ panel to the subfloor. Using a Cementous based flexibleS1 adhesive (Ultra Proflex SP) begin bonding FastTile+ boards to the subfloor using 8mm to 10mm square notch trowel.
- Install boards in a brick bond application above adhesive Compress FastTile+ board onto bed of adhesive for full adhesion which will create a 4mm to 5mm full bed of adhesive beneath panels, creating a flat and level surface.
- Using a screw and washer mechanically fix FastTile+ board to timber subfloor, it is advised to use 5 fixings per 1m2 and leaving a 30mm perimeter around edge of boards.
- Lay underfloor heating pipe into grooved channels and prime panels ready to accept floor covering.
- Material Composition:
- The insulation board is constructed from high-density, closed-cell extruded polystyrene (XPS) foam, ensuring excellent thermal insulation properties. The top surface features a durable, cementitious coating to provide a solid base for tile or floor levelling.
- Dimensions:
- 1200mm x 600mm x 20mm making it suitable for Fastwarm 16mm Underfloor Heating Pipe
- Thermal Performance:
- The board's insulation properties contribute to energy savings by minimizing heat loss and maintaining a comfortable indoor temperature.
- Pre-Grooved Design:
- The pre-grooved layout features channels with uniform spacing of 150mm to accommodate Fastwarm 16mm underfloor heating pipes.
- Load-Bearing Capacity:
- The robust construction of the board provides a reliable and stable substrate for flooring, supporting the weight of tiles and other floor coverings.
- Moisture Resistance:
- The closed-cell structure of the XPS foam ensures resistance to moisture, preventing water absorption and maintaining the integrity of the insulation board.
- Installation Ease:
- Lightweight yet sturdy composition facilitates easy handling and installation.
- Compatibility:
- Compatible with a variety of floor coverings, including ceramic tiles, natural stone, engineered laminate woods, LVT and low tog carpets.
