Some years ago the local "big city" remodeled the town library which started
life as a school building nearly 100 years ago.
"They" added plastic glazing to the existing windows.
I have a rental town house with 13 double hung divided light wood frame
windows which are about 35 years old.
"Someday" we plan to replace them all with "modern" windows but I wonder
whether $10 of that thin plastic glazing (not a film but only about 1/16"
thick) would "work."
The place has central air so while it is necessary they "operate" for safety
reasons, they would not routinely be opened for ventilation.
Anyone actually done something like this?
Any comments appreciated.
