How it works......

Embedded in screed
The heating tube is simply clipped to the standard insulation layer before the screed is poured. If the floor insulation meets the building regulation requirement, no additional insulation is needed. For mixed screeds, Heating Underfloor supplies an economical clipping track method for easy installation and accurate control of the tube spacing.

For use with liquid self-levelling screed, we supply clipping panels to cover the entire floor. These may optionally be used for mixed screeds.

With heat reflectors
Metal heat reflectors positioned in pre-tracked insulation material provide a versatile installation method. A floating chipboard decking may be used over it, or the insulation panels may be inserted between battens to take nailed timber.
In an upper floor, the scheme may be installed between the joists, working from above.Other Heating Underfloor schemes enable a low-height build-up on top of existing decking or solid floors provided they are pre-installed with adequate insulation.


Solid Floors

Solid floors are made with screed that is a smooth sand and cement mix, which is laid over an insulation base. Screed floors can be built up from solid foundations or in the case of beam and block floors, on intermediate floors

Hand laid screed is normally mixed on site or pre-mixed and delivered by a supplier. Hand laid screeds is the more common method for individual plots.

Self-levelling liquid screeds are delivered and installed by specialists. The screed is ‘pumped’ in liquid form and is quick drying. This method of screeding is more common for multiple/commercial projects.


Timber Floor

Timber joisted floors can be conventional joisted floors or TGI joists. These floors can be installed in the ground floor, but are more common in first floors.

If the joisted floor is in a first floor situation, then it is more common to install from below the first floor. If access cannot be gained from the underside, such as renovations or it is a ground floor installation, then the system is installed from above.


Floating Floors

Floating floors are a dry floor construction, built off a foundation slab, timber joists or beam & block floor. A dense insulation layer, over which either chipboard or the finished timber floor ‘floats’ on the insulation.

Floating floors can be installed in a new build, where it is assumed there is approximately 50mm allowance between the foundation slab/beam & block floor and the door linings. Alternatively, floating floors can be installed in a low height build up situation, on the ground or first floors, making it ideal for renovations this is known as overlay.


Overlay Floor

Until now underfloor central heating has been strictly for new homes or only as part of a whole-house refurbishment project. Installation caused significant disruption in every room and connecting to the central heating boiler was often a major headache.

Now with overlay floor heating system from Heating Underfloor you can lay a simple ‘low profile’ panel system over the existing solid or timber floor in any room. And it can be linked to the existing radiator system via our Zonal Regulation Unit.
