Insulation in a 100-year-old brick rowhouse
We’re fixing up a 100 year old rowhouse in Washington, DC, and wondering how / whether to insulate the two exterior walls. The walls are 2 layers of brick with lyme mortar, and originally had plaster directly on the brick (it was removed in a previous renovation). I was planning to stud out 2×4 walls, and thinking of using rigid foam insulation between the studs and the brick, and using spray foam to seal the gaps between sheets of foam.
Should I worry about moisture damage to the walls? Is there a better solution? I don’t want to have to hire someone to do spray insulation.
Any thoughts would be welcome. Thanks!
