Older properties can sometimes benefit from a retrofitted underfloor heating (UFH) system, but only if they have adequate insulation. In this blog, we’ll take a closer look at the insulation requirements when adding UFH as part of a renovation project.
Insulation considerations for retrofit UFH
Before starting your project, examine the Energy Performance Certificate (EPC) of your property and assess its insulation levels to see how you improve them. A well-insulated residence will experience less heat loss and need less energy to stay warm.
If your home has a concrete floor, you can add electric UFH without installing insulation as there will be negligible downward heat loss. However, if your renovation involves suspended timber sub-floors, adding a layer of insulation is imperative to maximise use of UFH.
Common insulation options
Tile backer boards and classic underlay are two popular insulation types for use with UFH. Tile backer boards work can strengthen wooden subfloors and effectively reduce heat loss. Boards work with both loose cable and sticky mat electric UFH equipment. Once placed, users can tile directly on top for ease of use.
Classic underlay is also known as Expanded Polystyrene or EPS flooring insulation, and is used widely to improve a room’s thermal efficiency. Lightweight and simple to fit, it’s popular for both commercial and residential applications. EPS insulation minimises heat loss by acting as a barrier that prevents thermal energy transfer below heating equipment.
