Customer requires structural opening formed and a french door fitted.Problem is he has found the style he likes but it,s 2 standard glass panel doors 2'6" .How much needs to be rebated off the edge where the doors meet and what size should the brickwork opening be prior to fitting of door linning.
Erm a rebate of half the door thickness and probably anything between 1/2" to 1" e.g. exposed to all weathers-1" partially covered-3/4" Interior 1/2" Brickwork opening (i dont deal with this side of the job really just mainly joinery) but..... you need to find out the thickness of the door lining and just allow clearance i think.
L O W For the brickwork . Check the opening for parallel , Plumb and Level. Never assume the brickie has left it so. In any event allow clearance for manouvere and packing . Wedge and fix. Cheers !
What sort of door is it? Unless its solid timber the rebate will take of the veneer/lipping and expose whatever is underneath
You could always glue and pin a rebate on of course. You'd just have to allow an extra 1/2 inch plus on your frame size and structural opening
