THE ongoing energy crisis is only serving to highlight how important it is that heating systems in buildings operate as efficiently as possible. With that in mind, floor insulation manufacturer Polyfoam XPS is highlighting the benefits of extruded polystyrene (XPS) when used with UFH installations.

UFH still has the reputation of being a luxury feature, as it’s rarely installed in buildings ‘as standard’. This is despite some of its potential benefits. Compared to a radiator system, for example, UFH can realise energy demand reductions in the order of 15%.

Unlike radiators, UFH warms rooms by a combination of radiation and convection heat transfer, and it can provide a more even spread of heat throughout as a result. And by removing radiators from walls, building occupants can enjoy greater flexibility in room layouts.

Where UFH is selected as the best option for a construction project, one of a wide range of systems will be employed. The choice of system depends on the building type, whether the project is a newbuild or refurbishment/extension, and whether the installation is at ground floor level or on an upper storey.

A good UFH installation directs as much of the heat into the room as possible. To minimise the flow of heat into the floor construction, UFH can be installed in the channels of specially-routed carrier boards made from XPS insulation.

The low thermal conductivity of the insulation maximises efficiency, while the robust nature of XPS means it can tolerate foot traffic from following trades. Its ability to maintain its performance ensures it’ll continue to deliver an efficient installation.

wet screed can be poured over, but carrier boards are particularly well suited to dry installations featuring a screed board installed prior to the final floor finish.

XPS is manufactured to achieve close thickness tolerances that ensure a consistent and level surface, avoiding any ‘steps’ in the floor that would hinder screed board installation, says the company.
