A neighbor has one of those fifties living room windows that consists of 12 smaller wood sashes assembled into a giant grid 3 wide by 4 high. One row of 3 are crank-out awning windows and the rest are fixed. Each of the 12 sashes are single pane glass with individual single pane storms held on by clips.
He got an estimate to replicate the whole thing with new double pane units for about $5000. The whole assembly is maybe 10 feet wide by 6 feet tall.
He has two ideas to upgrade what he has now instead:
A- Have a glass shop make up double pane replacement glass (about 1/2 in. thick), remove the interior stops, pop out the single panes and replace them with the double panes.
B- Have a glass shop make up double pane versions of the 12 storm windows.
Cost either way would be about $900 for the glass.
Do either of these ideas seem worthwhile, or do you think it makes more financial sense in the long run to replace the whole works? The sashes themselves are in great shape and the 3 operating sashes would get new weatherstripping as part of the project.
Appreciate your thoughts and experiences. Thanks.
