Fastwarm™ Solid18 panels are 18mm high-density gypsum-based dry screed boards designed to efficiently transfer heat from underfloor heating pipework to the finished floor surface. These pre-grooved panels are floated over a flat subfloor without the need for adhesive, making them an installer-friendly solution for both new builds and renovations.
Each panel measures 800mm x 600mm x 18mm and is grooved to securely hold 12mm pipework, including channels for main pipe runs, loops, and leaders to and from the manifold. This versatile design supports faster installations and reduces the need for additional components or cuts on site.
- Compatible with 12mm pipework – Grooved to accommodate straight runs, loops, and leaders for efficient pipe layout and connection to the manifold.
- No adhesive required – Panels float over the subfloor, simplifying the installation process and reducing prep time.
- Direct tiling or levelling – Approved by Ultra Tile for use with S2 adhesive and MSP primer for direct tiling, or with a 10mm Ultra Tile 2-part leveller for other finishes like wood, LVT, or carpet.
- High-density gypsum composition – Offers excellent thermal conductivity and structural strength, promoting even heat distribution and fast response times.
- Panel dimensions – Measures 800mm x 600mm x 18mm, providing 0.48m² coverage per board.
Fastwarm™ Solid18 panels offer a robust, time-saving solution that combines efficient heat transfer with installation versatility—ideal for a wide range of floor finishes and underfloor heating layouts.
