We're doing some work to our 1937 home and are concerned about a suggestion our contractor has made.
Some background, we'll be removing the plaster walls and putting up drywall, removing the radiators and installing radiant heat flooring, and replacing the original windows with new efficient ones. We have already installed a new efficient boiler.
Our contractor is saying that because the house is brick and was built with thick walls, when they remove the plaster and lath, they don't need to put up 2x4's and insulation behind the drywall. They'll put up wood strips and then the drywall.
Is this going to cause a problem in the future with moisture? Heat loss? Any concerns or is this normal building practice?
