UnderPlate for Suspended Floors

Our new UnderPlate system provides underfloor heating in timber suspended floors where the floordeck has already been installed or where the floordeck is to be laid prior to the underfloor heating pipe installation.

With a floordeck already in place the UnderPlate system is simply offered up between the joists from underneath and secured to the underside of the floordeck. Alternatively the UnderPlate can be installed from above and straddle the joist in order that a floor deck can be laid to allow trades to continue without damaging the underfloor heating. This is particularly relevant with an exposed deck open to the elements where progress of construction relies on a working deck to be in place.

In both situations the pipe is then simply pushed into the UnderPlate and once fitted, mineral wool insulation is placed between the system and the proposed ceiling to complete the installation.
