I am trying to design a greenhouse off the back of a house and I would like to make it double wall construction but still be able to see through it. What kind of material am I looking for and where might I go about buying it? I would like to pump air conditioned air between the 2 layers to smooth out any wrinkles and keep out any condensation. Any suggestions? Must be clear as possible and preferably built strong to last several years.

the plan is to roll up the cover in summer. Can't do that with glass, and it wont be as warm.

Some years ago, some friends and I were playing around with a DuPont product called Tefzel. It's a clear sheeting, comparable to common poly but much more transparent, much stronger, and, most astonishing of all, apparently immune to breakdown in sunlight. I had priced a 20x20 piece for a small greenhouse around the year 2000, as I recall, and was quoted something close to $1000!! I decided I could replace common poly many many times to get to that! But we did get some free samples since my friend was making solar panels and wanted to try it as a covering. I had some scraps paper-clipped together over a coil of black hose on my cabin roof for a shower water heater.....and they were still intact, flexible, and transparent ten years later!

Tim; Automotive convertible top rear window material. I have seen it it long rolls but i'm sure it would be cost prohibitive. Nothing will be truly see thru , especially with two layers. Look into a product called SOLEX opaque but truly cool stuff ! R- value , bendable , ten year warranty ! I have had it on my greenhouse for three years now and its as good as new , comes in a 49.5 " roll ,not cheap but free shipping up to a certain amount. The lighting is probably better than glass (no shadows) but you can't see out it . I have large glass windows on one side , but they are covered all winter long. I have one other glass window that I admit to leaving uncovered all winter , just so I can see outside ! In your case you might look at removable panels of glass or whatever material you choose . Good luck tom

Your right that you cant roll up glass, you would have to hinge a panel or make it removable. BUT there is no product out there that works nearly as good as glass for greenhouses if seeing through and durability is important. It also has the same R value per layer as plastic. ALL plastics are a compromise, usually based on cost. Glass is the ultimate greenhouse see through material. I hope you find some new miracle material that does all the things glass does for half the cost, but people have been trying for hundreds of years, and nothing has come close yet. Good luck Van

Why does greenhouse plastic block UV? Is it for the plastic and longevity when exposed to sunlight?

I've never been able to figure out why you would want to block UV for a greenhouse.
