Cellecta ScreedBoard 20 – Underfloor Heating Overlay board

Cellecta ScreedBoard 20 is a high density gypsum based board that can be used to overlay underfloor heating. The ScreedBoard 20 can be laid directly onto routed insulation offering a minimal increase in floor height. Due to it’s high thermal conductivity it is an ideal overlay board that allows underfloor heating to run efficiently with faster reaction times.

At only 20mm thick the low profile system offers a minimal floor build up. The ScreedBoard 20 looks and feels like a screed whilst eliminating the drying times associated with a wet trade. Tiles can also be laid directly on to the Screedboard 20 directly without the need for overlaying with plywood.

The ScreedBoard 20 is Robust Detail Compliant for E-FS-3, E-FT-5, E-FT-6 and allows underfloor heating to be incorporated into the acoustic flooring.

Frequently Asked Questions

What is Cellecta Screedboard 20?

Cellecta Screedboard 20 is a high-density overlay board, typically used for acoustic and underfloor heating applications.

Screedboard 20 is a 20mm calcium sulphate board that’s reinforced with cellulose fibre. It offers high thermal conductivity, allowing underfloor heating systems to operate efficiently, and helps to minimise running costs.

How does Cellecta Screedboard 20 compare with Cellecta Screedboard 28?

Cellecta provides Screedboard 20 and Screedboard 28.

Both are suitable for all types of steel, concrete, and timber floors. They look and feel like screed and can accept all types of floor coverings, including tiles.

However, Cellecta Screedboard 28 is used to combat unwanted airborne and impact noise, whereas Cellecta Screedboard 20 offers excellent acoustic properties and can also be used to overlay underfloor heating systems.

Another distinct difference between the two is their thickness. Screedboard 20 is only 20mm thick, whereas Screedboard 28 is 28mm thick, including a 20mm facing board and 8mm resilient layer.

Cellecta Screedboard 20 is also slightly lighter than Screedboard 28, weighing 25kg/m².

Whilst Cellecta Screedboard 28 is a robust treatment for E-FS-3, E-FT-5 and E-FT-6, Screedboard 20 is also FFT4 compliant.

What are the benefits of using Cellecta Screedboard 20?

Cellecta Screedboard 20 offers numerous advantages.

Due to its low thermal resistance, combined with its rapid transfer of heat, this product is brilliant for underfloor heating applications.

Another benefit of using Cellecta Screedboard 20 is that, unlike standard screed, it provides quick drying times – meaning you won’t have to wait too long to apply the final floor covering.

Once installed correctly, it will accept a wide range of floor finishes – ranging from wooden flooring to carpet, ceramic tiles, and vinyl flooring.

Screedboard 20 is made from 100% recycled high-density gypsum and cellulose, making it an eco-friendly option for homes and businesses. On top of this, it delivers unparalleled performance and complies with Robust Detail.

Is Cellecta Screedboard 20 easy to install?

Yes, you’ll be pleased to know that Cellecta Screedboard 20 is both quick and easy to install.

No screws are needed – just a tape measure, Pro adhesive, YELOfon FS/ES strip, hand or circular saw, 6-8mm packers, and club hammer.

When installing Screedboard 20 atop an underfloor heating system, you must make sure you carry out the necessary tests (including pressure testing), and never use the heat from the system to dry the adhesive.

With that said, the team at JCW Acoustic Flooring can take care of the installation for you – ensuring that the overlay boards are laid correctly and efficiently. We have been installing Cellecta Screedboard 20 for more than 15 years, and work hard to complete every job quickly without skimping on quality or safety.
