Kitchen extension

[irishhurricane@gmail]

Hi. I'm new to the forum, so helllo and thanks in advance. I'll soon be ready to screed my kitchen extension floor and currently have 250mm difference between sub floor and existing floor. I've got 100mm of Quinntherm to go in which will leave 150mm screed. Sounds a lot?

Yes, sounds a lot, why not increase the insulation? Lob another 75mm on top of the 100mm.

If it's normal screed 75mm will do you.

Any UFH or just having a slab?

Just a slab, no ufh.
