Wet Underfloor Heating

Screed

Solid Screed System is the most popular wet underfloor heating system, this solution can be used to install the underfloor heating pipes within a screeded floor.

  1. Clipped direct with staples
    ✓ A thermal insulation board is laid directly onto the solid sub floor first, if insulation is foil faced, ensure a 500G Polythene membrane is installed over.
    ✓ The pipe work is clipped directly into insulation, once the pipe work has been pressure tested, it is then covered with either a sand and cement screed or a pumped anhydrite screed.
  2. Castellated panel system
    ✓ The pipes are clipped into egg crate style plastic panels, laid over thermal insulation, which is then covered with either a sand and cement screed or a pumped anhydrite screed.
    ✓ The castellated panels ensure uniform pipe spacing, for faster and easier installation to achieve the recommended heating output.

By installing the pipes within the screed, this enables the whole floor to warm up like a storage radiator. This method works efficiently with any floor covering, as long as it is well insulated beneath and is normally used for new build houses or extensions/conservatories.
