I've been lurking on this forum for some time, first post.
I just found a bunch of old aluminum storm doors, and walked away with 6 nice tempered glass frames. I'd like to use them for unopenable windows. At first I thought I could build the frames to the size of the aluminum frame and install the complete thing. But it seems like removing the metal frames and installing the glass in a wooden frame would remove a serious vector for heat transmission (aluminum being a very good conductor).
Have any of you experience recycling tempered glass in aluminum frames? I like the idea of using tempered glass as a safety concern, and also the price was right (ie, free)

Bury the aluminum in your wood frame, that's what the insulated glass with aluminum spacer folks do.

Storm doors are typicaly single pane. There about a step up from a tarp to me so I wouldnt put to much effort into making them more efficient.

Imo the sgl pane is going to be the biggest component to the heat transfer than the alum edging buried in the wood framing.

Double pane is going to double the R value, make the inner pane removeable so you can clean between them. Basically storm windows. Keep the space between under 3/4", wider sets up convective loops, something Jefferson didn't know when he did that at Monticello. I built a house in the 90's that had non sealed upper end Pella doors with blinds between the removeable panes. Nearly all of our windows have lost seal and fogged, thinking of all the replacements that happen, not very energy efficient in the overall scheme of things.
