Brick house, no insulation
We have a brick home built in the 50s. It has plaster walls with about a 2" gap between the plaster and brick with no insulation. I have read all the debates regarding insulating behind the existing walls. So here is where I need help. Could I build 2x4 walls over the existing plaster and insulate them and then cover them with drywall? What would be the steps? Vapor barrier? There is none in the cavity now. The house is on a slab. I live in northern Indiana where it is cold and windy in the winter. The exterior walls are very cold to the touch. I have insulated the attic.
Thanks for any help you can give!

If there's A 2" gap what's the plaster attached to?
Contacted any local company's that do foam insulation yet to have them do any on site quotes?
You could add that wall but you would also have to add jamb extensions to all the window and doors.

I'm interested as well as to what the plaster is attached to.

Maybe a bunch of goony feathers?

Apparently no sheathing on the studs.... just the cavity/air space (required for brick veneers) that you don't SPF directly on the brick.,d.cGU&cad=rja
