We are re-roofing our house... finally.
We are also converting the loft (when we get to it), we have a target u value of 0.18 W/m2k for the roof.
Rafters are currently 87mm x 55mm @ 400 centres, part of our structural work is to increase the rafters with a 50 x 50 batten on the underside (to allow removal of collar ties in the bedrooms for vaulted ceilings) so this would give us 137mm depth, but obviously I could choose to batten out further to allow for a greater thickness of insulation between the rafters (rather than under)
since we are taking the roof off anyway we seem to have a lot of options, we seem to have even more endless possibilities and combinations, of above, between and below.
Is there anyone out there that can point me in the right direction for a cost effective solution?
Many thanks in advance.
