WARM-­BOARD utilises an 18mm high density dry screed board, which acts as a heat conducting surface, transferring the heat from the pipes to the heated floor above. Once up to temperature, it delivers sufficient heat output to provide warm and even ambient temperatures within the living space. The best floor coverings to combine with the WARM-­BOARD, are hard surfaces such as stone and tile, as they offer the least resistance to heat transfer compared to carpets. The main benefit of the WARM‐BOARD, is the option for the direct application of tiles, as it can be applied directly with the use of flexible adhesive. However, in most instances, a 6mm ply cover is recommended prior to tiling. When floor coverings such as carpet are to be fitted, the system design must factor in the extra heat output that will be needed; this loss in output needs to be negated by increasing the flow temperature.

WARM-BOARD uses a unique patent pending End Support system, which helps to secure and support both the floor covering above, and the pipe work within. WARM-­BOARD can be fitted directly above concrete or floorboards in both retro fit and new construction applications, with the potential for the direct application of tiles to the board; with its versatility, it offers a quick and easy installed solution.

The WARM-­BOARD 12mm MULTI-­PEX 5 layer pipe, is laid from the chosen manifold location in a serpentine pattern, and secured at pre-­grooved 150mm* pipe centres within the WARM-­BOARD. The pipe is then supported by the End Support with its self-­retaining pipe locking system, enabling a quick one man installation.

Dependent upon the floor covering, different floor finishes can be applied to the WARM-­BOARD, these include, carpet, laminate and vinyl. The type of floor covering will affect the maximum heat output of the floor heating system, typically 83 W/m2**. An optional intermediate layer should be laid on top of the WARM-­BOARD, that being, our 10mm dry screed board, or a 6mm ply board. This intermediate layer is required prior to laying carpet or laminate floors. As an alternative, a carpet can be laid direct to the WARM‐BOARD, this is possible if all gaps around the recessed pipe work are filled in to form a level surface, achieved by applying a self levelling compound. SOLFEX Energy Systems always recommends that, insulation is to be fitted below the floor heating system to reduce downward heat loss***


*For 12mm diameter pipe, the maximum floor coverage is approximately 12 m2 with pipes laid at 150mm apart.
* For 10mm diameter pipe, the maximum floor coverage is approximately 9 m2 with pipes laid at 150mm apart.
**This is based upon an intermediate 6mm ply board layer followed by tiles.
[Based upon calculations from BS EN 1264 part (2)
***Provided by others-­ In accordance with Part 'L' of the current Building Regulations, to ensure that any downward heat loss does not exceed 10W/m2, in accordance with BS EN 1264.
