Heat Emission Plates – FFA


The ‘FFA’ system is a plate system designed for joisted or batten floors, and forms part of our ‘In-Base’ product range. Plates are made from aluminium for high heat conduction whilst keeping the weight to a minimum compared to steel alternatives. Designed for various joist and pipe pitches, the 16mm underfloor heating system is installed prior to the floor deck and mechanically fixed to the top side of the joists.


Suitable for both new and existing buildings. Insulation, normally mineral fibre, is laid between joists and secured to maintain direct compressed contact to the underside of the plates. Plates are nailed or stapled to joists to cover about 80% of the floor area. A minimum 5mm gap to be maintained between plates for thermal expansion. Joist notching and hole drilling to be carried out in accordance with the current Building Regulation and manufacturers instructions.
