Insulation Board – RF


The ‘RF’ system is a low-profile high density board with an aluminium foil face suitable for direct fixing to the sub-floor. As part of our ‘On-Base’ underfloor heating range, the 20mm thick XPS400 insulation board is pregrooved for 16mm underfloor heating systems. The main panel design includes both straight pipe runs and radius returns for ease of panel layout and installation. Boards are light-weight and easily cut.


Suitable for both solid and timber subfloors, the lowprofile insulation boards can be used for multiple floor finishes. Carpets, tiles and LVT finishes will require a renovation screed capping layer prior to installation. Combine with other ‘On-Base’ board systems to produce an optimised underfloor heating system to suit different sub-floors and varying floor finishes.
