Hello all. I salvaged over 100 framed single pane windows (2'x4') I'm thinking about using them to build our greenhouse.

The more I read here the less Confident I am about the idea.
Should I save these for another project and perhaps go with the poly?
It gets quite cold here In calgary zone 3a and at the very least I'd like to extend the season a few months.

I was thinking about doubling up the glass with a 2-3 inch buffer zone.

If I do go with the glass the next problem is how am I going to attach them to the wooden frame and deal them?

I was thinking of running a channel saw down the faces of 4"x4" posts and sliding the glass in there. Changing a broken pane would be a pain tho.

Any better ideas would be greatly appreciated.

You can build the greenhouse as a stand alone structure.
Frame the glass in the manner you described, albeit with thinner lumber.
Hang the framed glass on the greenhouse structure. If a panel breaks, you can remove only that framed piece.

Screw through the wood frame of the glass directly to the walls of the greenhouse. Put the next frame of glass tight against the first, screw it to the GH wall and to the first frame of glass. Caulking or weatherstripping between the frames of glass will give it a tight seal.

I wish I could that sounds great. But I've got aluminum frames and not much frame 1/2" at most I'm afraid ill break a lot of glass if I'm screwing or drilling through metal that close to the pane. I could give it a few test runs with pilot holes I suppose.

You can pinch them onto the wall.
Leave a gap between the frames.
Add a board to the outside.
Sink a screw through the outside board, between the gap, into the wall studs of the GH.

View is looking down from directly overhead.
Brown=GH wall stud
Blue = glass, framed or unframed
Orange = outside board
Black = screw

if the wall studs are spaced apart just right, you can use cleats

add a board wider than the wall stud to the outside of the stud
screw or nail in place
set the glass against the outside board
add a narrow board to the inside corner
screw or nail this into the wall stud

Ill need a lot of weather stripping. Any ideas to get it cheap?
