Old's cold frames.

Old. Lots of comments on your cold frames, but most were directed toward a carpenter project involving rabbeted frames etc. No one really answered the question, that is , "is there a type of cement that could be used"
Well, I think there is. Cement layesr use a urethane product in their seams. It is tough, waterproff and indestructible. Also if you shop the big building places you will find construction adhesives in about four grades. One of those should work. Just lay a bead down with the gun, and press them down. Should hold for a 30 degree tilt.

Well the tilt probably will not be that great. Figure what ever you would get if you cut a 2X10 that was 28 inches long from corner to corner to get the angle used. Reason I asked about the silicone clear caulk is that I have 2 half tubes of the stuff on hand. The whole idea is the keep this costing $0.00. I have the lumber which cost me the trip to get them. I have the glassed and payed around $5 for that 10 years ago and I have the caulk on hand plus the screws. So you see I'm trying to do this with out costing me any thing more then a little time

Old, I assume you are talking about the glass overlapping the wood frame by a 1/4 to 1/2 inch on all four sides. I've done that with plexiglass, not regular glass. It worked well. If it sticks to glass, which I think it will, you are in business.

rich, we used to have "hot boxes" is what we called em to transplant the seedlings into before going in the garden. used old storm windows and made the boxes to fit the windows. 2x12 buried so about 3 inches of board stuck up off the ground. just laid the windows on top of the boxes. no angles, just flat. your silicone should work fine. all we did was put a block of wood under the window during the day for ventilation so the box didnt overheat. if there was a danger of hard frost, put a small lite bulb in the hot box over nite.

Didn't plan to have it over lap but be flush with the edge of the wood. O know years ago before my parents house burned they had a porch that was on the house and it had fiber glass panels for a roof. My dad had used silicone to seal between the mobile home roof and it. Well they wanted to take it off to add on so I went up and cut the legs from under it and the silicone held it up and I even got in and jumped in it and it still held. I had to cut the thing loose to get it to fall off so I know silicone is very strong

Agree. An overlap would just be a hazard, cut some kid or animal. Keep it flush or inside the frame just a little. Guess you could also hold it down with some washers on some wood screws. Careful though. Just enough to keep the panels from sliding, not dwon pressure, crack for sure.

This stuff is tempered glass so if it cracks you end up with a million pieces of glass in a heart beat.

CLTX · Feb 19, 2010

If I were overlapping, I would run a bead around the exposed glass edge with an extra dob at the corners, to protect anyone/anything from harm. I've never tried it like you said, but I would want a tight fit all the way around the glass. If you had good success before, it should work. Think it will hold those big, fat coons? ...lol.

As for the coons not sure it will or will not just hope they leave it alone so I do not have to find out. Now as for the cats I bet I'll be cleaning off cat tracks all the time, making me think that maybe I should glue 2 sheets together so as to be stronger since this tempered glass is only about an 1/8 inch thick and I do have 22 sheets of it so doing 2 would not be hard to do
