Insulation Board – RRB


The ‘RRB’ is a low-profile high density rigid board with a glass-fibre reinforced cement finish suitable for direct fixing to the sub-floor and tiling. As part of our ‘On-Base’ underfloor heating range, the 20mm thick XPS300 insulation board is pre-grooved for 16mm underfloor heating systems. Available in multiple panel designs, site routing is reduced and loop returns are incorporated without requiring additional components.


Suitable for both solid and timber subfloors, the boards can be used throughout a floor or tiled rooms only. Boards can be either mechanically fixed or adhered to the sub-floor ready for tile application. Combine with other ‘On-Base’ board systems to produce an optimised underfloor heating system to suit different sub-floors and varying floor finishes.
