Hello. I’ve recently been laying celotex 150mm myself in my extension ready for the UFH and screed.
When coming to the folding doors I’m not exactly sure what to do to bridge the cavity.
I’ve read a couple of threads on here about filling with concrete but I’m not sure if this is right. I’d also contemplated standing up some celotex on its end. Any advice would be appreciated.
I’ll try upload or host a pic somehow
