Cutting rafters next to the purlin for Velux window

OKOK · 1 Jan 2018

Just curious, what is the best way to attach trimmer and double joists. M10 bolt and nuts or just big wood screws?

Big wood screws, or nails and corner plates - or both.

Coach screws. Trimmer on hangers

I'll be putting an inch batten under the tile battens to have the 50mm air gap and then filling the rafters with 75mm PIR insulation followed by Superfoil SF19 moisture barrier plus plasterboard, etc.
