For a domestic property it s best not to exceed a screed thickness of 65mm.
Floor screed thickness underfloor heating.
4 liquid screed for underfloor heating systems.
A thick screed will give a longer reaction time the time taken to warm up and cool down while a thin screed will have a quicker reaction time.
Screed underfloor heating systems heat up and cool.
The thickness will have a significant impact on how the actual ufh will distribute the heat.
An underfloor heating system in concrete relies on the thermal conductivity of the screed to transfer the heat to the rooms.
Screed systems are traditionally used in new build projects.
It may be a slow response system so the underfloor heating should be on 24 7 during the heating season with setback options available.
The thickness of the screed in which the warm wet pipes sit will have a dramatic impact on how the system is used.
When used with many flooring materials underfloor heating can cause problems if the temperature at the interface between the subfloor and flooring exceeds 27 c or is subject to rapid fluctuations in temperature.
This would have an impact on the property s sap rating as the additional screed depth means the underfloor heating system will have to work harder to heat up.

2 1 insulation shouldn t stop at the floor.
Screed thickness over underfloor heating minimum should be based on the high spot in the building assuming that a level floor screed is required and not a profile of the substrate.
The low spot will mean an increase in depth.
