Screed, underfloor heat and bifolds !! Help

[spike66k]

Thank you again!
Last request.....is there an off the shelf additive (flexidry/rono stuff) that my good old fashioned builder can add to the screed he's gonna knock up!
It would be nice to reducing the drying time, so we can tile quicker. Any suggestions on the makeup of a good screed would be gratefully received!
Thanks!!!!

My screed was one with fibres in but I wouldn't rush it anyway - we left it a few weeks then put a very thin layer of self level on so we could tile direct but my system was wet UFH. in the rooms where i put cable down it was existing sub floor.

Yep, we had the fibres too & was is no hurry to cover it.
Can't remember exactly but this it was more than 2 weeks before I covered it with 10mm insulation boards
