Underfloor Heating Screed Installation in London & The South East

Advantages of Underfloor Heating Screed

Underfloor heating screed is a specially formulated material designed to enhance the performance of underfloor heating systems. Unlike traditional sand and cement screeds, underfloor heating screed is engineered to provide superior thermal conductivity and flow characteristics, allowing it to evenly distribute heat across the floor surface. 

This type of screed is typically applied in a thinner layer, which not only reduces the overall weight but also accelerates the drying time, enabling quicker installation of floor coverings. The self-levelling properties of underfloor heating screed ensure a smooth, flat surface that is ideal for various flooring types, making it a preferred choice for modern construction and renovation projects.

What is Underfloor Heating Screed?

Underfloor heating screed offers many advantages which are: uniform room temperature, comfort, safety and space saving. Also, underfloor heating is well adapted to all forms of energy production: particularly renewable, low temperature systems, such as air and ground source heat pumps.

Drying times

Drying time for a screed is approximately 1mm per day, up to 40mm. Beyond 40mm, 0.5mm per day. Underfloor heating, may also be used to reduce the screed drying time you can put the underfloor heating on after 7 day to help speed up the drying time to 2mm per day up to 40mm. After 48 hours, the building must be properly ventilated.

Our flowing screeds – Gyvlon Screed THERMIO+ or CLASSIC when combined with low temperature underfloor heating achieves maximum comfort and energy savings. Our screeds offer many advantages over a traditional cement based screed:

  • increased conductivity
  • faster room heating and cooling
  • homogeneous heat delivery
  • better heating efficiency

Gyvlon Screed THERMIO+ has been specially designed to deliver a higher guarantee of thermal performance. THERMIO+ allows you to get to improve your floor heating by:

  • Performance: up to 30% increase in thermal emission coefficient for maximized performance of underfloor heating
  • Comfort: up to 80% thermal diffusivity for a more responsive rise in temperature
  • Cost savings: up to 8% savings on the heating bill

Common Questions About Underfloor Heating Screed

People often ask whether they can use traditional screed with underfloor heating. You can, but you’re not getting the best from your system. The improved conductivity and complete pipe coverage of liquid screed makes such a difference to performance that it’s worth the investment. When you factor in energy savings over the life of the system, liquid screed pays for itself.

Another common question is about cracking. Liquid screed has minimal shrinkage compared to traditional methods, which means less risk of cracks during drying. We also install movement joints where needed, particularly in larger areas or where you’re meeting different floor constructions.

Timing is always a concern on building projects. When can you walk on it? When can floor finishes go down? For our standard liquid screed, you can walk on it after 48 hours. Floor coverings depend on the type – tiles can often go down sooner than wood or carpet, which need lower moisture levels. We’ll give you specific guidance based on what you’re installing and the screed depth.
