Timber suspended floors use joists to support the floor deck. The underfloor heating system can either sit between the joists or within the floor deck itself. If an acoustic treatment is laid over the suspended floor then an underfloor heating system for a batten or floating floor would be more suitable.

There are five systems available from Timóleon for suspended floors.

The Toron flooring system is suitable wherever a chipboard or plywood floor deck is to be laid. Standard plain panels of chipboard or plywood are substituted for 22mm panels of either material pre-routed with a pattern of channels into which circuits of 12mm pipe can be pressed. After the pipe has been inserted, it is covered with self-adhesive foil which acts as a diffuser fin. A layer of either 6mm ply or laminate flooring or hardwood strip or thin compressed gypsum is then fully-glued over the top. The resulting composite panel becomes stronger than the original standard flooring panel. The Toron system provides an excellent heat output and is designed to work at low water temperatures.

The FoilBoard ECO system is designed to sit in-between the floor joists and is manufactured from FSC approved wood fibre insulation providing good thermal, acoustic and fire retardant properties. The FoilBoard ECO system is ideally used when a timber wood strip finish is laid directly on the joists.

The FoilBoard Suspended system is a 100mm thick heating panel designed for suspended ground floors. The FoilBoard panels are manufactured from insulation and have an integrated aluminium diffuser. Once installed within the joist space the panels reduce draughts and significantly improve the insulation level of the floor.

The InterDeck system is designed to allow a continuous pipe underfloor heating system to be installed when the floor deck is already in place. 12mm pipe is threaded through the joists from the floor below and installed into the InterDeck panels that are fixed to the underside of the floor deck.

The FoilBoard Modular system is used when the floor deck is already in place. The modular panels with pre-installed pipe are installed from the floor below.

If you are considering a batten floor installed over a suspended floor as used in acoustic separating floors please see the Batten floor construction section.
