Insulating 1943 brick veneer house

| Posted in Energy, Heating & Insulation on
My house was built in 1943, The walls of my house are 6″ cinder block with a brick veneer. The inside of the blocks where painted with what looks like a black tar based coating to act as a waterproof coating so the moisture from the bricks would not come inside. The original walls had no insulation in them just 1×4 furring strips and drywall. I want to insulate the walls some of which will remain 1×4 furring and others that will be 2x4s built away from the block. I don’t want to create a problem with moisture in the walls and wonder how they should be insulated and what kind of vapor barrier?
Thanks Tom C.

I presume from the fact of the waterproof coating that there isn't a cavity between brick and block.
Whatever you decide on the internal walls, it would make sense to give the external brickwork a waterproof coating.
I have used a silicone liquid coating that soaks in and doesn't alter the appearance of the brickwork and will withstand UV exposure.
