Leaky Old Windows
The air infiltration is awful. You can feel a breeze when you stand near the windows, and we really need to seal them up, but I don't know what to do, since we don't want the windows to be caulked shut. We replace the storms with screens and leave the windows open on nice days in the spring, summer and fall, and we don't want to do anything that will make that impossible.
One thing that is definitely in the works is replacing the storms. We are considering (and this is going to contradict what I just wrote in the paragraph above!) putting in permanent storms that will stay in place all year and not be removable in some of the windows. The other windows will have replacement storms that can be swapped for screens, so that each room will have at least one window that can be opened for fresh air.
I think we are also getting a lot of air around each pane of glass. All those little panes are individual small sheets of glass. I don't know how to "caulk" around the lead muntins, though. (Is "muntin" the right word?) I'm sure that there's some special glazing compound for that, but I don't know what it is or how to use it.
But in the meantime, how do we stop the gales of February from sweeping through our first floor?
