Available height limiting factor
In renovation projects, the available building height is often a limiting factor. If possible, it is desirable to avoid having to carry out expensive and time-consuming jobs, like that of raising thresholds and adapting of doors. By installing electric underfloor heating, wall space, previously occupied by radiators or panel heaters, is released, providing greater flexibility for furnishing of the room. One can argue that this makes the room larger.
Fast and easy temperature regulation
A floor with retrofitted floor heating is usually very quick and easy to regulate since the heating cables are located in the upper part of the floor construction. This gives great advantages with respect to temperature regulation and minimizing power consumption.
Nexans low profile heating cable products
Nexans offers a variety of low profile heating cable products. Some of these can be mounted directly onto combustible surfaces, such as chipboard flooring, and then be covered by a thin layer of screed, or directly in tile adhesive. Others may be installed directly under parquet or laminate without the use of screed at all. If available building height permits, there are also traditional heating cables which are suitable for renovation projects.
Heating cable or heating mat solution
Installation in a renovation project can be implemented using either traditional heating cable type TXLP, or the thinner mat solution MILLIMAT. Another alternative is the MILLICABLE™ and MILLICLICK™. The latter system (8 mm building height) is intended for parquet or laminate flooring, and there is no need for use of screed.
The thinnest solution for wet room floors
Installation of the MILLIMAT®/150 heating cable mat requires a noncombustible subfloor, where it is laid and covered by screed. Alternatively, it may be covered by tile adhesive directly, but the layer of screed/adhesive (covering the cable) must always be a minimum of 5 mm. Total achievable building height may be less than 1 cm, but in wet rooms there must always be a slope towards the drain, so parts of the floor will, inevitably, be thicker. On subfloors which risk deflection, a minimum (total) screed thickness of 2 cm is often recommended (by the screed supplier) to ensure strength and prevent the top floor form cracking. Follow the recommendations and instructions given by the supplier of the screed.
