Liquid screed for underfloor heating

Underfloor heating is now the source of heat in many residential and commercial buildings. Providing a well distributed output of heat that covers the entire room. It is a welcome addition to any building, particularly in the colder months.

Liquid screed for underfloor heating

Liquid screed is ideal for underfloor heating systems. Designers, property developers and architects increasingly incorporate liquid screed into their new build or renovation projects, knowing that it assists the heating system in maximising heat output.

Clockwork Screed are experts in the supply and installation of liquid screed for underfloor heating systems.

Which screed works best for underfloor heating?

Factors to consider when deciding which floor screed to use with an underfloor heating system are:

Thermal conductivity

The rate at which heat passes through a floor screed will impact the performance of the underfloor heating system.

Speed of drying

During the construction or renovation process, a fast drying screed will benefit all contractors, the efficiency of the project and meeting agreed deadlines.

Risk of bubbling or voids around pipework

An underfloor heating system is an intricate array of pipework that needs to be adequately covered to generate high performance.

Shrinkage

Once laid, the floor screed should have minimal shrinkage.

Clockwork Screed’s cementitious liquid floor screed performs exceptionally well in all these areas, making it the ideal choice of floor screed for underfloor heating systems.

Benefits of liquid floor screed

The benefits of liquid floor screed are well documented, particularly in maximising the effectiveness of underfloor heating.

The Clockwork Screed liquid floor screed has been formulated to provide exceptional thermal conductivity which enhances the performance and responsiveness of underfloor heating systems. This is due, in part, to its strength which allows it to be laid as thinly as 25mm. Such a thin layer facilitates the spread of heat from the pipes.

Liquid floor screed also allows for the even distribution of heat across the floor which is more beneficial than having isolated points of heat from traditional radiators or heaters. Liquid floor screed is also quick to install.

At Clockwork Screed we can cover 1000m² a day which helps to keep project costs to a minimum. Once laid, liquid floor screed is fast-drying and allows footfall within 24 to 48 hours. This means other contractors and trades can get back onto site quickly to restart work.

Because liquid floor screed self-compacts, there is no risk of bubbles or voids around the pipework of the underfloor heating which further enhances its performance. Clockwork Screed products also have shrinkage rates of less than 0.05% which is better than many other cement-based screeds.

Our liquid screed's quick drying time can be especially useful when installing underfloor heating systems. Sceed is commonly used to create a level and smooth surface for underfloor heating systems to ensure efficient heat transfer from the heating pipes to the floor surface.

Because liquid screed dries quickly when used to cover underfloor heating pipes, the heating system can be operational sooner. This can help to shorten the construction timeline and reduce the amount of time that other trades must wait before starting work. Furthermore, faster drying time means that the underfloor heating system can be commissioned earlier, allowing for early testing and resolution of any issues.

FAQs

How much liquid screed can you install without joints if an underfloor heating system is fitted?

Up to 100m².

How do you install liquid screed?

We use our unique mobile screed plants which can be operated by a single team. This is more efficient than the traditional method of using a truck mixer to transport the screed to site and having a separate contractor pumping, levelling and finishing the work.

Do you offer the full floor screeding service?

Yes we source, deliver and install your floor screed.
