Don’t have drawn comb. Any particular configurations of boxes/frames you do when going to double brood?
I leave maybe five sealed brood in the bottom box and the open directly above, on the premise that sealed gives heat and open needs it. If you just stick a second BB on top of the first they're just as likely to use it as a super on a strong flow, defeating the objective of providing extra laying space.
On the other hand, it's a good plan to put a brood box of foundation above the QX on a strong summer flow, giving you a stock of good combs for the future. Although they won't have had brood in them, safer to spray with Bruco to preserve them from wax moth.
A vertical split keeps the nest compact and makes the most of rising heat; this particular colony is on a solid floor; I don't use dummy boards, but have in the past used insulation boards.
As Ian said, you won't be doing this unless you have plenty of bees; I'd add that you must be able to read the colony - what were they like last year? Some of mine in Surrey were on triple brood by June, and the colony upgraded yesterday has already about 10 pounds of nectar in the super added two weeks ago, so I know their game.
