Moisture concerns with adding framing to old brick house
I'm concerned about potential future moisture problems.

I bought an 80-90 year old double brick house in Pittsburgh. I began removing the horsehair plaster and lathes in some sections due to water damage, then continued around the house after I found knob & tube wiring and decided to gut it.

I'm going to add framing to the exterior walls (which will also allow me to insulate well). Assuming any cracks in the brick/mortar have been repaired:

1. Can my studs touch the brick wall, or should I leave a space to prevent wicking water?
2. Do I need to add a plastic vapor barrier between the wood and the brick?

Thank you in advance for any advice you can provide!

There are a lot of houses with solid bricks walls in the UK, and many of them have been insulated by fixing studs, either metal or timber to the walls. A vapour check is used on the warm side of the insulation.
However insulated plasterboard(sheetrock) with a built in vapour check is often used instead and can be put up using the dot and dab method.
These sites may help.

You do need to be aware that changing the way an old house breathes can sometimes upset the balance of it's moisture control and cause problems.

Thanks for the advice. After addressing the cause of the moisture infiltration (a space large enough to see the ground outside) I felt much more secure about proceeding with typical studding/insulation. Thanks again!
