Interior storms on newer (1980) casement windows worth it?
My wife and I moved into a ~1980 house in September 2019 in the Twin Cities, MN. The house has double-pane casement windows that appear to be original.
I’ve spent hours looking for information on whether it’s still a good idea (i.e. “worth it” to do something like interior storm windows… all the articles are addressing the ~100 year-old single pane double-hung windows.
Generally speaking, is there a reasonable ROI for installing interior or exterior storm windows on a more recent window?
As far as we can tell, the house is well constructed using best practices and quality materials available at the time.
If there’s other information I can/should provide please just let me know.
