I'm installing new soffits & fascias from scratch to an extension we are doing just now, and am wondering if there is a particular way they are normally constructed. Soffit depth would be approx 200mm.
Intention is to have 6x2 rafter ends cut vertically then a 25x200mm softwood fascia nailed on to the rafter ends with 50mm above the top of the rafter (allowing for 25mm of sarking board and 25mm kick for the eaves course). Does the softwood fascia screw directly to the rafter ends, or should there be any heavier timbers in-between the rafter ends. (pieces of 4x2 for example)?
2x2" timber screwed onto the outside face of the blockwork right at the top (under the rafters) such that some 9mm marine ply can be nailed up from below, with the ply behind the fascia, rather than the fascia on top of the ply, right? I'm assuming I need to bore a 70mm (approx) hole between each pair of rafters (every 600mm?) and fit one of those circular plastic vents. Is that right?
