Probably just me who is as thick as a brick
When I look at UPVC back doors a popular size seems to be 840mm wide. But when I look at bricks they are 215 wide and so with a 10mm mortar joint I cannot get 840 to be a round number of bricks in the gap.
890mm gives me a nice round number of bricks (four bricks wide with three mortar joints). 840 gives me three bricks and a nasty extra bit that doesn't look right.
Who makes the wrong size thing? The brick maker or the door maker?
