Tar paper is used to allow the wood to breath. It is like Poly but it breaths. I used R22 Roxul Insulation (Rock fibers) in the pony walls.
There is a downside for sure to build under the trees. I made sure to cut down any weak branches. We do have very severe weather and are known for our Thunder storms during the summer almost EVERY evening with high winds. I do worry about the trees and the trees are about 80 years old (4 of them). that was the only location that was large enough for my greenhouse design. I can't take the trees down because I don't own the home.... We hope we purchase an acerage this summer and then I will have a permanent perfect location for my greenhouse.

I have several of these, I use them for roof vents so I don't personally have experience using them for side vents but the springs are strong and should pull closed without gravity. I bought mine from Charlie's Greenhouse, at the time they were the only place that had these with the higher temperature "orchid wax" actuators but the Bayliss openers are often on backorder at Charlie's. I see that several other places now carry the ones with orchid wax. They are made in England so maybe they will be easily available in Canada. |
Thank you! This looks promising. I'm going to have to get 3 of them. I hope I can find them here in Canada. Or I will try and get shipping from elsewhere!
