Flo-screed is applied in 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 screed is far more robust than conventional screeds, reaching strengths of 30N/mm2 allowing it to be laid earlier in the build process, this has a number of advantages including allowing the screed to continue drying as the build progresses resulting in being able to lay final finishes such as tiles at a desired point in the build and also will act as a physical datum throughout the build process allowing for accurate and faster installation of door linings, stud partitioning, skirting boards, kitchen units and stairs etc.
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.
The key features of liquid underfloor heating floor screed
Produced to a controlled flowable consistency to fully encompass the heating pipes.
Pump placement 100m vertical and 180m along the floor, no risk of barrow damage to door frames or underfloor heating pipes etc.
Accuracy of placement and surface finish. (Laser levelled) easily achieves SR2 under BS8204.
Elimination of voids resulting in a uniform heat transfer and maximised thermal efficiency of the underfloor heating system.
Reduced screed depth when compared to traditional sand and cement screeds minimising heat storage , resulting in a floor which responds rapidly to the users requirements
Extremely low shrinkage- can not curl and minimises the risk of cracking.
Does not require reinforcement
Heating systems can be commissioned in accordance with BS1264:2001-4, 5 days after application of the screed.
Minimal thermal expansion (0.012mm/Mk)
Excellent thermal conductivity (2.2W/Mk)
Flo-screed is the ideal floor screed to compliment underfloor heating as it has a 30% increased thermal efficiency over traditional floor screeds
Renovation Flo-screed can be laid as thin as 25mm thick over existing solid substrates making it possible to produce a new level floor to continue your renovation project off without removing the existing substrate therefore saving on the cost of excavation and disposal.
Over insulation Flo-screed can be laid as thin as 35mm as a floating floor over insulation.
Over underfloor heating Flo-screed can be laid to a depth of 30mm above the top of the underfloor heating pipes. Typically 50mm
