Floor Constructions

There are an increasing number of floor constructions which you can now incorporate underfloor heating within. 

These will all fall within 3 broad categories:


When looking at a new build or extensive renovation, this is the most common construction for ground floors. The underfloor heating pipe is laid on an insulation layer using a cost effective fixing method such as staples or cliptrack. A screed is then laid over the pipes, this forms a thermal mass and gives a high heat output.

It is increasingly common to use a screed on upper floors, this can be on a beam and block concrete floor or more recent innovations such as a Lewis Deck.


Regardless if you are considering conventional or engineered joists, there are a number of solutions. To avoid any changes in levels, the most common form of install is aluminium plates, these bridge the gap between the joists and are formed to hold the underfloor heating pipes. 

They are available to fit from above, or below the joists and are available in several sizes to suit different joist spacing.


If you have an existing solid floor, or are building on top of a joisted floor, these are options that will increase floor height. Considerations will include the additional height increase on the floor, insulation levels on the existing floor and final floor covering.


Retrofit options are available that will increase the floor height from as little as 15mm before final floor covering.
