Floor Construction Details
We’re here to help with your infrared heating enquiries
Choosing the correct underfloor heating product depends on both your subfloor type and chosen floor covering.
The following construction details show the recommended floor build-up for the most common finished floor coverings.
In some cases, there may be more than one suitable product or construction method available. Your final choice may depend on factors such as floor build-up height, installation speed, ease of fitting, or cost. Whichever option you choose, you can be confident that it is a proven solution designed to deliver an efficient and reliable heating system.
Insulation materials are an essential part of all the construction details shown. Using the recommended insulation will help the floor heat up faster and operate more efficiently.
