I have nearly cleared the loft of the limited old loft roll and the crap left by the roofers who installed the new roof.
The loft is spacious, I want to deck the floor for storage use and install lighting and power up there. The joists and rafters are 4x2's which seem very small but obviously years ago that is what they used.
So I now have no insulation in the roof/loft. Given that there is ample space up there I had planned on fixing 50-70mm PIR to the rafters. The idea being that it would give a nicer environment in the loft and that i wont have to cross batten the "floor" to install 200-300mm loft roll.
Is there any issues with this approach and if I go down that route is there any point in installing 100mm loft roll between the joists as well? I have seen loft storage convertor videos online that do both but I have never understood the reasoning, if you insulate the joists why then insulate the rafters?
