Insulation and avoiding cold bridging

[janedevon]

Hi guys my noob question of the week is upon us 

 

we are going to put our floor insulation in at the end of this week as we have first fix plumbing taking place next Monday

 

we have a block amd beam floor at present and ready to go is sand for blinding, then a radon barrier/dpc then we require 100mm celotex before our ufh goes in then concrete pour.

 

my question is the concerning the edges of the rooms, we are planning a 50mm celotex upstand on all edges of external walls to avoid cold bridging, do we put this in place first or on top of our 100mm celotex, we have a batten above ffl to secure plasterboard to so i plan on i sulating with the 50mm under the batten then by the time plasterboard and skirting goes in it will be well covered.

 

thanks
