Made a mistake with placing rsj 178x100 slightly too high (one end is built into an external wall, the top of the rsj being 230mm below a second storey window cill)
this is for an single story roof (span 3.2m, 38deg pitch beam centre 1.6m)
rafter spec was 150x50@450 centres with 100mm insulation between, but with tiles takes the mid point too high
is there any way i can still create a warm roof with having to lower my beam to get the ridge tile low enough ???
