Select your finish Tiles Stone/Marble Carpet Floating Timber Vinyl In Screed or Directly Below the Floor Covering Secondly, you will need to select if the underfloor heating is to be installed directly below your floor covering or underneath a sand and cement screed. All systems are designed so they can be installed directly below the floor finish without the need of a screed or self-levelling. When installing directly below the floor covering it does ensure there is minimal height build-up and fast response time (both heat-up and cool down). However, in some situations it is preferred by the builder or person laying the floor finish to have the underfloor heating installed with a screed layer. This ensures that the heating system is protected while the floor finish is being laid and it also ensures that there is a flat surface for the floor layer to work on. When installed within the screed it does mean the heating will take longer to heat up (approx. 1hr longer per 25mm of screed) however will also hold the heat for longer. Matting or Loose Wire Underfloor heating systems can come as a matting or loose wire system. With the matting systems the heating cable is all pre-spaced on the self-adhesive mesh which allows for quick and easy installation especially in large open areas. The loose wire systems are used for small or awkward shaped areas. Floor Finish Lastly select your floor finish to find the recommended solution.
