I’m dealing with some 1930’s era steel casement windows, Tudor revival style, that are in reasonably good shape for the most part. They need some maintenance and would like some suggestions for how best to handle this as gradually applied DIY work.
Some windows aren’t fitting so well and are hard to close. I’ve used WD-40 on parts and cleared out excessive paint layers that were in the way. This helps but perhaps there is warping that needs to be addressed? Anyone have experience with this?
Another thing I’d like to address is draftiness. The windows are just steel, no gasket material anywhere. That may have been the original design, or perhaps the gaskets all disintegrated over the years? Are there standard practices for ensuing well sealed steel windows? There is a sizeable air pocket between the outer and inner mating surfaces that perhaps was where a gasket used to live.
Finally, I’m wondering if there is a way to replace the single pane glass in the casement with double pane or some more insulative glass at reasonable cost. The pocket is probably deep enough to fit standard thickness double pane glass, but I don’t know any supplier that produces double pane glass in such a small size that I could glaze into there. Is that even something I would want to do? I’m guessing it would cost a lot, even for a few windows. I’m familiar with window films that can help with radiative losses, but perhaps there are other window glass options I should consider? Any laminated options, like what some cars use, for strength, acoustic, and thermal improvements?
