the plates and enable this system to still be installed. On new floors, insulation is laid between the joists. Heat emission plates
are used to spread the heat evenly, the plates being secured directly onto the battens or joists. The groove in the plate is designed to grip the pipe securely. Once the loops are laid, connected up and pressure tested, the floor deck can be fixed to the joists. Joists are usually spaced at 400mm centres, double heat emission plates can be used without raising the floor level. For battened floors, the battens can be fixed at either 400mm or 411mm to suit the two sizes of double heat emission plates. The 411mm plates are specifically designed for use with Junckers sprung floors. The maximum heat output from timber flooring is 70W/m2 temperature of 20°C and a floor temperature of 27°C
with a room
Floating floor system: This is an ideal system for retrofitting UFH, or as an alternative to screeded floors. The system comprises of pre-grooved 30, 50 or 70mm polystyrene insulation floor panels and end returns designed to be used with heat emission plates. The floating floor panels can be laid on almost any existing floor surface.
It is essential that the floor is clean and level as any imperfections in the slab will be projected through to the finished floor. If self levelling com- pound is being used to level the slab it must be allowed to dry before lay- ing the floating panels. Most floor finishes can be laid on top of this system, apart from tiles.
Overlay system: This system is designed specifically to enable UFH to be installed in areas where floor height might be an issue. The panels are made of dense fibrous material and are only 18mm deep, enabling UFH to be installed over existing floors. The pipe used in this system is 12mm in diameter. The panels get glued to the existing floor with special glue and most floor finishes can be laid on top of this system. Again, a levelling compound may need to be used to take out any imperfections in the floor prior to the installation of the boards.
