Hi Guys
Quick question.
I am carrying out a loft conversion. No Dormer, just roof windows.
I need to double up the rafters, and trim for the roof windows. I also need to double up the rafters in order to install the insulation, as at 90mm the current rafters aren't deep enough.
My plans state to install new 6"x2" rafters along side the existing.
My question is, I cannot install rafters full length wall plate to ridge due to the purlin position. So is it ok to fit these in 2 parts, ie wall plate to purlin, then purlin to ridge?
If 1 piece were possible, I would have to notch out at the purlin anyway to fit around the purlin as the new rafter is deeper than the available gap.
For insulation purposes the rafters aren't structural and just to allow the depth for insulation.
For roof window they are structural, as they are added to take the weight of the window and compensate for the removal of rafters and addition of trimmers.
Cheers
