I though we could share ideas as to how to overcome freeze ups of greenhouse doors and vents.

You thoughts and comments are welcome here.

Even since I installed my Andersen sliding door I still often find the door frozen to tight to open. I was thinking about possibly mounting a heat tape, like those used for pipes, around the door frame. I thought I should be able to accomplish this using Gorilla Duct Tape applied with a heat gun after drying thoroughly and wiping the surface with alcohol.

That ought to work, Ric. IF you wanted to "dress" the door, you could do the same with those light-ropes, using the older kind with bulbs that get warm. The newer, LED ropes don't get warm at all.

Shoot, Ric -- we have a problem with the sliding door on our house freezing up (never mind the GH). Let me know when you get this figured out Big Grin

I'm trying WD40, it's suppose to displace H2O. It's a shame I don't have as much metal exposed inside as out. It would make using a heat tape easier. If the WD40 doesn't help I may try buttering up the bottom track with white marine grease. The bad thing about that stuff is it collects dirt and causes more wear.

Would graphite work? I don't have freezing issues but I use it on the zippers of our greenhouse because it's dry and doesn't collect more grit.

The WD40 didn't work, and thanks but I don't think graphite would either. I can and have used some table salt in the track, this does work, but that may cause excessive corrosion. If I dried everything off some afternoon and watched where the condensation pools in the track, I may be able to drill some drain holes at key spots. Hmmm? Thoughts anyone?

I greased up top and bottom tracks, Ric. Debris does collect some on that bottom track, but when I close the sliding doors, all that is pretty much pushed to the center of the track and I just pick it off. Debris is therefore not really a problem at all.

Ken, I think I've narrowed the problem to condensate pooling in the lower track. Since the metal is much more exposed on the outside it conducts the cold and freezes. I'm afraid the continued use of salt will cause excessive corrosion, although that's what I used on the original HFGH door. The door seems to ride exclusively on the rail, on the nylon wheels so I'm thinking I can drill holes through the flat portion of the metal and a cross hole in to the wooden sill plate from the inside. The WD40 did help with freezing condensation on the door jam and upper guide.

Thumbs up

Your rails are pretty much backwards from mine then, Ric. Mine mainly ride on the upper rail and the lower rail simply sort of guides those two sliding doors.

Would putting a large piece of solar pool cover over it - like a secondary door - help in any way? Maybe it would keep it just a few degrees warmer. It could roll up on the outside when you need to go in.

I feel your pain ... almost. A couple days ago I thought I wasn't going to get into my little 6 x 8 GH here in central Texas - but a little shove broke the ice loose. I thought of you -- and was glad it wasn't colder or wetter here.

You can see my flap rolled up over the two sliding doors.

That's probably the most important side for morning sun. I really don't want to cover it up. The sun on the lee end can raise temps 15*F in an hour at 20*F and a 15mph wind outside. Confused

I can assure you Ric, this solar blanket material will only increase your heat and only diffuse the light on that end of your GH.

I probably have a big enough piece to blanket that end.

yeah, I have seen a nice increase in the warmth from the solar cover, so I don't think you would lose any nice sun Eric. I have a flap on my door, but I roll it down on the inside to keep the cold air out. If we had very many more days like this week where the door might freeze closed, I would also be adding one to the outside.
