/ Old Window Greenhouse #31
I built one 15 years ago. Had old windows from a house I tore down, had some 2x4's, had screws, and a screwgun, and at that time, had some energy, so.... boom. 2 days= free greenhouse. Still standing. The intense heat dried up the old window glazing putty, and a couple of wdows rattled loose in the wind, but didn't break. I siliconed them back in. Some of the mullions are rotting, but still hold. If I did it again, I would pound some clear 100% silicone over all the putty making sure the bead makes contact with the glass on one side and the wood frame on the other, and I'd be more diligent about repainting the frames every 5 years. That way it would last a long time. But hey, 15 years for a free greenhouse (10x10) is not so bad either. and it's still going.Anyone built a greenhouse out of old windows? Starting a project and looking for advice.
