  • Non-screeded underfloor heating system
  • Lightweight boards
  • Quick installation

Grant’s Uflex and Uflex MINI Overlay System is a dry, non-screeded solution for underfloor heating systems. The lightweight boards, available in either 16mm or 20mm thickness, can be laid directly on top of most types of new and existing floor surfaces, making them ideal for retrofit underfloor heating system installations. The Uflex and Uflex MINI pipe is positioned into the pre-formed grooves which makes installation straightforward and, being low in profile, the overlay system causes minimal increase to the existing floor height.

What benefits do Grant’s Overlay Underfloor Heating System deliver?

What benefits do Grant’s Overlay Underfloor Heating System deliver?

The Grant Uflex and Uflex MINI Overlay System is a dry system which means that you do not require a wet screed which is traditionally poured over underfloor heating pipework. This makes the Overlay System a popular choice for retrofit projects because it can be installed quickly, whereby installers can fit the robust, high density polystyrene boards on top of an existing, suitable floor surface, lay the pipe into place and then fit the new floor covering directly on top.

The Uflex and Uflex MINI Overlay System uses boards which are available either foiled or non-foiled. The foiled boards have a bonded layer of aluminium foil on the upper surface which enhances the transmission of heat across the floor. Whichever type of board is used, the system is designed to effectively transfer the heat from the underfloor heating system into the room making this heat emitter an ideal partner for heat pumps.
