Evening all
I need to put the loft insulation (2 layers of 150mm loft roll) up and board the ceiling on my extension. Last time I did this it was chunky six inch joists so I put a layer of insulation over them then put more between the joists which tended to stay put so I could then board it.
This time it’s trusses so a lot smaller depth on the ceiling cord, just after some advice on how best to do it, can I put 2 layers laid across the Trusses and not have any between, leaving an air gap between ceiling board and insulation? Or am I best fitting each 6x3 board then put the insulation above it?
I’m sure trial and error will probably tell me but any advice welcome
Cheers
