Technical – Flowing Screeds
Flowing screed is applied in a liquid form, as the screed is applied it flows around the pipe forming a void free screed. No voids mean greater conductivity allowing heat to diffuse evenly in the screed.
The physical properties of the material allow for a thinner screed therefore there is less material to heat so the room reaches its desired temperature earlier, similarly when the heat source is turned off the screed cools faster resulting in quicker response times and approximately 30% improved efficiency over traditional sand and cement screeds.
In many cases the specification would be 75mm of conventional sand and cement screed When it is replaced by liquid screeds, the screed thickness will be reduced and the overall thickness of 75mm can be made up with EPS (expanded polystyrene insulation/Jablite).
This will provide economies in the amount of screed used and will clearly enhance the acoustic and thermal properties as well as leading to a more rapid drying of the screed as a direct result of the reduced thickness.
