I no the majority of builders use cavity wall closers, but when I build my single storey garden office with a 100mm cavity with flat roof, so I use cavity closers to close the top of the cavity wall???
Also, would like to have a look at some pictures of flat roof installations of timber so that I can do it myself to save money. I have been looking at cold roof and warm roof installtions and cant decide which is going to be best for me, I quite like the idea of having the insulation between the joists but not sure where I would put my air vents for flow of air
