Floor screeds are used with underfloor heating to distribute heat across the floor and to increase efficiency by acting as a thermal store. They also provide a protective layer around the underfloor heating pipes.
As screed transfers heat very well, this gives an even temperature in the floor, keeping the room comfortable with no cold spots.
Underfloor Heating Screed provides a thermal store through its mass; it stores the energy and releases it slowly over time. Thermal mass increases efficiency by building up the energy store and then using small bursts of low temperature energy to keep the floor and hence the room at a consistent temperature.
There are several points to consider when specifying screed such as compressive strength, floor thickness, screed finish, speed of installation, curing and drying times.
Our screeding teams use material supplied by major manufacturers and will work to the datum level you supply on site. The screed will be laid in accordance with BS8204, the British Standard for screeding, giving a quality finish.
Supplied by the main screed manufacturers; there are two main types of floor screed used with underfloor heating:
- Traditional sand/cement.
- Free Flowing Anhydrite based screeds.
