Product Description

ScreedBoard 20 high density interlocking floor boards featuring extensive underfloor heating benefits, ScreedBoard 20 dry screed boards have the lowest thermal resistance when compared to the most common floor finishes (chipboards & wet screed). Low thermal resistance allows ground water heat pumps and heat recovery systems to work efficiently to provide significant cost savings for the consumer. ScreedBoard 20 floorboards accept ceramic tiles, feature easy to install interlocking edges, and don’t contract or expand when exposed to water.

ScreedBoard 20 is the ideal product for floors featuring an underfloor heating system due to its low thermal resistance and rapid heat transfer characteristics. ScreedBoard 20 is also suitable for acoustic flooring applications incorporating an underfloor heating system, when combined with FIBREfon 8.

Questions & Answers


How many sheets come in a pack?


These sheets are sold individually, one sheet covers 0.72m2.


Hi can I use this instead of floor boards over joists ? I already have wet underfloor heating installed in aluminium heat trays between joists.


Hello, we would suggest asking Cellecta for this information, we cannot talk on behalf of our suppliers.


How do the vynal tiles adhere over these boards and do they need to be bonded down to the concrete underfloor with adhesive as well.


We would ask you to talk to Cellecta in regards to this quote, as we cannot talk on behalf of our suppliers.
