It was my birthday on Saturday so as part of my gift, as well as buying me all my remaining ceiling materials, my wife took the kids out for the morning to let me get a few hours at it, so here's where I started the day...

And here's where it ended. 50mm insulation laid across the 100mm at right angle, all edges foamed then 11mm OSB2 screwed across the top.

Little bit down one side that needs some offcuts cutting and fitting in before finishing the overboarding. I'm also going to lay a piece over the underside of the ridge beam then OSB over that to cover up that cold bridge, I'm guessing that's the right thing to be doing...
Plan is then to paint both the ceiling and the OSB storage area floor white for reflection and also making it easier to see any small bits against the floor. Electrics will be surface mounted in trunking but I need to make a call to Building Control to make sure he's happy with that, otherwise I might need to reconsider this approach...
Will try and get out there and do another hour or so tonight to keep the momentum up.
Cheers
Mark
