A screedboard (or screed board) is a high-density, dry floor panel manufactured from calcium sulphate (gypsum) reinforced with cellulose fibres. Designed as a modern alternative to traditional wet screed, screedboard creates a solid, monolithic floor finish without the water, weight, or long drying time associated with sand and cement screed.
At JCW Acoustic Flooring, our screedboard range includes:
Cellecta ScreedBoard 20 is a high-density, gypsum-based acoustic flooring deck that can be used to improve acoustic performance and safely overlay underfloor heating. Because of its high thermal conductivity, Cellecta ScreedBoard 20, is an ideal overlay board that both protects underfloor heating and allows it to run efficiently with faster reaction times.
Cellecta ScreedBoard 28 is the only single-layer solution for timber frame buildings that is compliant with Robust Details. It is suitable for use with underfloor heating and all finished floor types and, when compared with any other acoustic flooring system, it offers the best acoustic flooring legislative requirements.
Cellecta Screedboard systems provide a faster, cleaner, and more efficient solution for residential and commercial flooring applications. Whether installed over concrete, steel, or timber floors, screedboard delivers structural strength, excellent acoustic performance, and superior thermal conductivity for underfloor heating systems.
Both options are compliant with UK Building Regulations and Robust Detail requirements, making them suitable for new builds, refurbishments, and high-performance acoustic applications.
Traditional wet screed introduces moisture, heavy materials, and significant drying time to projects. In contrast, a dry screed board like Cellecta:
Screedboard can weigh up to 75% less than traditional wet screed, making it ideal for multi-storey developments and city-centre projects where transport and structural loading are key considerations.
This lightweight yet structural screed board also preserves floor-to-ceiling height compared to wet screed builds.
All Cellecta Screedboard products are supplied in a practical 600mm x 1200mm board size with precision interlocking edges.
The many advantages of this dry screedboard include:
The boards can be cut with a hand saw or circular saw, allowing easy installation around services and room perimeters for a perfect fit.
Manufactured from high-density gypsum, Cellecta Screedboard delivers:
Its high-density composition ensures compatibility with ceramic tiles, carpet, and other finishes without the need for additional overlay floorboard layers.
The Cellecta Screedboard systems we provide are suitable for:
They are compatible with a variety of floor finishes, including:
This makes screedboard a versatile overlay floorboard solution for multiple flooring applications.
Cellecta Screedboard 28 is specifically developed for enhanced acoustic insulation in timber frame and steel construction projects.
Featuring a unique resilient layer, Screedboard 28 provides acoustic performance typically 5dB better than legislative requirements, helping projects meet and exceed Part E of the Building Regulations.
Screedboard 28 is compliant with:
It is suitable for use within proprietary treatments and Robust Detail systems across England and Wales.
The interlocking edges further enhance sound insulation by reducing flanking transmission between boards, maintaining acoustic integrity across the floor system.

These are both types of high-performance insulation board, available in different thicknesses to suit different purposes.
Cellecta Screedboard 20 is a 20mm–thick, interlocking high-density gypsum board designed primarily for underfloor heating applications.
Key Features:
Screedboard 20 offers significantly lower thermal resistance than acoustic chipboard flooring or wet screed alternatives, improving reaction times in UFH applications and reducing running costs by enabling heat to transfer efficiently into the room.
It can be used with underfloor heating systems and can be installed directly over suitable insulation or structural subfloors.
On the other hand, Cellecta Screedboard 28 is a 28mm–thick board incorporating an integrated resilient acoustic layer, making it ideal for timber floors and Robust Detail constructions.
Key Features:
If you need help choosing between these types of screedboard, please contact us by phone or email, Monday to Friday.
Sometimes misspelt as ‘Selecta board’, Cellecta Screedboard is predominantly used in timber frame and steel projects where a quick-drying screed underlay is critical.
It is a practical, dry alternative to wet screed within Robust Detail proprietary treatments and legally compliant systems, including:
So, whether you need a screed board for concrete floors and walls or a high-performance acoustic screedboard, Cellecta products from JCW Acoustic Flooring can deliver the following benefits:

When you choose JCW Acoustic Flooring for dry screed board solutions, our screedboard installation service is simple and efficient.
To fit dry screed board flooring, you must:
Because it is a dry screed board system, there is no wet trade, no curing period, and no extended drying time. Floors can accept foot traffic quickly, and final finishes can be installed far sooner than with traditional wet screed.
At JCW Acoustic Flooring, our team will lay the screedboard for you, ensuring the area is completely covered with a professional finish. You can then choose to leave the screed board flooring exposed or apply further flooring materials on top.
If you have any questions about this process or how it works with underfloor heating applications, just get in touch with our team.
