Retrofitting Low Profile Underfloor Heating

Thermal comfort of underfloor heating for existing and old buildings

The FLEXIRO low profile underfloor heating kit with corrosion-free and flexible 10 mm PE-RT plastic pipe is designed for retrofitting in areas up to 10 m². For larger areas, several systems can be combined and connected to the existing heating system using RTL boxes.

The water-bearing underfloor heating is connected between the supply and return pipes of the heating system in the same way as a conventional radiator. Existing radiators are either replaced or operated in conjunction with the underfloor heating, such as the towel radiator in the bathroom. Clip-on rails or stud plates, special plug-in connections and detailed installation instructions and videos make the 17 mm flat underfloor heating easy to install.

Upgrade individual rooms, such as the bathroom or kitchen, with thin underfloor heating. Bring the thermal comfort of FLEXIRO into your home.

The Bostik company says yes! However, floating timber structures are not permitted as they are highly susceptible to deformation. Installation is therefore only possible on fixed timber structures, whereby these must be uncoupled. Please contact us for further information on laying on fixed timber structures!

The existing substrate must always be level, clean, dry and load-bearing.

FLEXIRO underfloor heating can be installed on OSB boards. Bostik's instructions clearly state that the OSB boards must be bonded to the substrate. Floating OSB boards are not suitable. The OSB boards must be primed before laying the FLEXIRO underfloor heating. In this case, the pipes should be covered with at least 5 mm of screed.

Due to the installation of the low profile underfloor heating directly below the surface, additional insulation is not required in most cases. This keeps the installation height low. Exceptions are floors above unheated basements and the ground. The requirements of the Energy Saving Ordinance must be observed. Further information on thermal insulation for underfloor heating
