Ever wondered about the benefits of dry screed floor over traditional screed floors?

Here is all you need to know, including why they are a great solution for underfloor heating systems too.

What are dry screed floor panels?

Dry screed flooring panels/ boards are precision engineered from the highest-quality gypsum fibreboard to create strong monolithic floor structures. The slim, dense boards have a solid floor feel when installed. System solutions are available whether you are adding screed to a solid substrate or need a spanning solution over joists, pedestals or on a cradle and baton system.

What are the benefits of dry screed panels over traditional screed?

It’s about saving time

Whether building on site or in an off-site factory the boards are quick and easy to install. The boards come in the form of interlocking panels and the installation system requires just 24 hours before being fully trafficable. This allows floor finishes to be installed much sooner than with traditional screed.

Reducing water usage on site

As the dry screed panels are secured using glue and/or screws there is no requirement for water to lay the panels. This saves approximately 11ltrs of water for every 1m2 when compared to 75mm of traditional screed, (based on water costs of £119 per 1000ltrs) saving £1,309 for a 1000m2 project. On top of this, dry screed boards eliminate the need for daily wash out of the pumping equipment and disposal, saving both the water usage associated with this and the challenge of disposing of the waste water.

Save space with dry screed boards                                  

Due to the high density of the boards, they provide the support needed without adding significant height to the floor. In commercial uses an 18mm board will often be sufficient, significantly less than the 75mm needed with the traditional method. This gives up to 57mm extra floor to ceiling height in each room.

Soundproofing dry screed boards

The high density boards are particularly effective at minimising noise, but when backed with wood-fibre, they provide further enhanced acoustic performance and excellent impact in sound reduction. Fabulous news for projects such as multi-occupancy residential, hotels, hospitals and schools.

Using under flooring heating (UFH)? Dry screed boards are the ideal solution and here is why.


There are benefits to using dry screed floor panels every step of the way.

  • Commissioning can be completed 24hours after the floor is laid. As soon as commissioning is completed you can then start applying floor finishes
  • If you discover a snag after installation remove the board, fix the problem and replace the board. No need to wait for the wet screed flooring to dry again.
  • Increased response time as the boards heat up and cool down quicker than the wet screed alternative
  • 43% more thermally efficient than chipboard, that give improved response time along with reduced running costs

All of this is great news for installers and end users alike.

Boards that tick all the environmental boxes

When used with under floor heating, the system will reduce CO2 emissions due to its increased thermal efficiency when compared with chipboard and improve under floor heating response times compared with traditional screed. It will also optimise the benefit of air and ground source heat pumps. So whether it’s during the build phase or when the building is occupied, Knauf dry screed boards are helping to reduce the environmental impact of the building.

The Knauf range of dry screed flooring, available through Encon, offers boards suitable for use on solid substrates, over cradle and baton systems, direct onto joists or with pedestals.
