Grant’s Uflex system makes underfloor heating a viable option for a wide range of projects, from one-off new build projects and room extensions through to larger multi-property developments.

Grant’s Uflex underfloor heating system is embedded into the floor construction so is ideally suited for new builds whereby the pipework is fitted during the initial stages of the property’s development. The Uflex pipework is then positioned and clipped into place once the flooring’s insulation and membrane has been fitted, after which a flow screed is laid over the top and allowed to fully dry before the heat source is introduced.

Features & benefits

  • *25yr Guarantee on pipe work only.
  • Easy to install
  • Grant's Uflex uses a flow screed system, as opposed to a solid screed system, meaning that the drying time is much quicker with the flow screed mix drying in thirty days.
  • It has a unique edge insulation, which consists of a self-adhesive edging strip which is located around the surrounds of the area in which the screed will be laid. This strip comes with a ‘skirt’ design which provides an overhang which curves alongside the wall. This edging strip not only contains and seals the screed, it also serves to reduce heat loss out via the walls.
  • Quick reaction time- Working with room thermostats, the system’s temperature can be easily adjusted without needing to switch the heating on or off which, over time, can reduce the overall demand on the heat source.
  • Zone control for optimum comfort
  • 16mm PE-RT pipe
  • Good for continuous running with setback control
