Screed on timber floor
Jan 20th, 2016, 10:34am
 
Hi

Has anyone experience of putting a floating screed on a timber floor? Im looking to install underfloor heating on a timber floor, and want to raise the level and have the thermal mass of the screed to hold the heat.

I have timbers175x50  @400  ctrs, and propose 70mm insulation between them, and a separating mmembrane before 75mm screed and tile or wood flooring.

How do you verify the victorian timbers can take the load and wont deflect and crack the screed?

Thanks

Bob

I would avoid screed for this.

We have a mixture of screed and foiled insulation (aka heat spreader plates) in our house. Both work equally well although the screed takes longer to heat up - perhaps a disadvantage if you are both out at work most days.

I would be careful to do this. I personally wouldn't as it will simply crack after a while.
