Just What Is The Underfloor Heating Screed Minimum Thickness?
I’m Andy Parkin Managing Director of the Multi Awarding Winning Speed Screed. Today I would like to talk about underfloor heating screed thickness minimum.
Wet Underfloor Heating
When we talk about underfloor heating in this example we are talking about “wet” underfloor heating as apposed to electric systems.
All the following information is based on 15mm pipes, other than 10mm pipe with the low-profile system.
Screed thickness minimum is 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. We would always recommend a full survey of the substrate takes place before laying any screed. This way there will be no nasty shocks with levels.
Minimum Screed Depths
- 35mm to 45mm total depth of screed inclusive of pipe (dependant on product chosen).
- 22mm total depth of screed
Traditional Sand And Cement (1:3 & 1:4)
- 65mm total depth of screed
- 55mm total depth of screed
- 45mm total depth of screed
That covers the major types of screed.
I hope you now have a better understand of the underfloor heating screed thickness minimums, however if you have any other questions please contact us. We love to help!
