Fit From Below Plates

The Hetta Fit from Below Plate system allows underfloor heating to be installed in timber suspended floors where the floor boards have already been installed or where the floor boards are to be laid prior to the underfloor pipe installation.

The Fit from Below Plates are installed in between the joists from underneath and are screwed to the underside of the floor boards.

The pipe is then positioned in to the hanging grooves and once fitted, insulation is placed between the plates and the ceiling to finish the installation.
