Need to replace old storm windows
One possible cheap fix, but kinda scares me.
I worked in a glass shop for a few months. And we often made our own windows.
Was needed in commercial buildings and some odd ball residential windows.
In the shop we always had different stock of different aluminum window framing.
We always had 4'x8' sheets of glass on stock of different thickness.
For dual pane glass and tempered glass, we always ordered it in correct size and dimension then just built frames for them.
Any decent glass shop, could build you one window in about a 1/2 hour.
Not a lot of labor, single pane glass is fairly cheap, price of aluminum is up.
But would be pretty reasonable for a custom made window.
Just the thought of putting them up and down and storing them every year, all the broken glass that could happen ... but hey, our grandfathers did it.
If it was easy, we would not call it work!
