Help! triple wall polycarbonate or double glass
Comments (3)Hi Kat The polycarb will diffuse the light but it won`t reduce the amount of heat entering the greenhouse by much overall so the mass will still warm up. When you consider a greenhouse is usually full of plants so very little direct sun will make it to the north wall ;) Don`t forget to insulate on the outside of the stone wall and use a radiant barrier on the inside of any wall/roof section that isn`t being used as thermal mass or letting in the light....See More5-wall or dual 3 + 2 wall polycarbonate for lean-to?
Comments (11)John, A ghetto greenhouse! Seriously! The corner and center posts are 4x4 treated posts set in concrete. In between are 2x4s. One one side I have a 77" glass door and same size window that neighbors set out on garbage day. On the other side are a couple of 2'x5' windows (about 8x12" glass panels). The bottom foot or so on the sides and front will be 7/16" particle board insulated with R-30 insulation, as will be the back wall. The front will be the poly and since it is only 16 ft' long and the walls will have 4' of poly, I'll have two panels left over for the sides. (Rough Brothers sell the poly in 24' sections.) The top is 13 mil woven plastic but I'm dazzled by the light it lets in. Near the top of the back, it's over 90 percent on a sunny day (according to my lux meter). Seedling at the bottom of the back wall and in the middle are doing much better than they did this spring under 35,000 lux, but when I'm done, the back wall will be lined with Mylar. Yeah, www.roughbros.com. For the plastic, I talked with a guy at a paint supply store. He works part-time at a large greenhouse and the GH uses the same six mil plastic Pat sells to painters. What's more, it is far cheaper than what GH supply places charge! If my experiment works - that is I can raise close to 50 tomato plants that produce ripe fruit as they should, once the plastic needs replaced I will with the twin wall poly. As for the space between the poly and plastic, it will be 3.5" - the width of a 2x4 or 4x4. IME, as long as the layer isn't too wide, it works fine. I live in a very old house with old, drafty windows. I cover them with plastic in winter and the glass inside stays warm - there is about 2" from the glass to the plastic.

Comments (4)There is also www.FarmTek.com - they have twin-wall panels made by Palram, custom @$5.95 per 4' sheet and 4x8' sheets @ $41.95. Shipping seems to be $7.00 per linear ft per package up to 12' - to a maximum no. of sheets per package of 50. They also have a roll of twin-wall corrugated plastic: 8' wide; each @ $7.39 per linear ft, and a 250' roll @$6.95/linear ft. They don't say what the shipping/freight charges on that would be. You can also call them - 1-800-327-6835. While I am not sure how much they would be price-wise compared to local sources, their prices for the water filters I have bought from them seems to be competitive ($5-7 against what I priced at Lowe's a few years ago at over $15!) - they have stuff for agricultural growing and storage, so they carry everything that can come under that heading - the specialty catalogue I just got, for that only, runs to 352 pages....See MoreIs a NanaWall worth it?
