I have 2 wood frame greenhouses. The smallest one is 14' x 18' and the larger one is 23' x 26'. I also have two 16' x 96' hoop houses. The roof and lower sides are covered with corrigated fiberglass. They both have storm windows covering the entire center of the sidewalls. I use an attic type fan with a thermostat and louvers to ventilate. I usually wrap the outside in 6 mil plastic during the winter and the fan turns on automatically if the temp gets to high. They are heated with 30,000 BTU ventless propane heaters. We recently moved to a new location and I definately will be using the double wall polycarbonate to cover the roof and sidewalls on the new greenhouses. I still plan to have windows that open. I have seen advertisements for a double wall polycarbonate which comes in rolls that can be used on hoop houses etc. I plan to check this product out for covering the tops of the hoophouses. There are images of all of the buildings on my web site (Link Below)under the Greenhouse menu. The larger one has a design flaw - the roof is to flat and condensation drips from the roof about half way down instead of flowing to the sidewall gutter.

Most welcome. I love, love, love my wood slat blinds. Be prepared to spend a bundle, though! Esp. Hunter Douglas - very expensive, but they're well made. I didn't go with HD because of the cost, and I'm kind of regretting it. One bit of advice: know the white you have on your would trim, i.e.: Benjamin Moore White Dove, whatever it is. Go to a hardware store that sells that paint, get a chip of the color, and take it w/u to the blind store so you can match the white as best as possible. They do come in dramatically different whites, and presumably you'll want the blinds to match the wood trim and window grids as best as possible, if you go with the wood blinds. The way the film goes on is you spray the window with a water/detergent blend (you can make it yourself or you can buy the bottles of it that 3M and Gila make for it, but all it is is water and I think a blob of dish detergent. I looked it up online and made my own). Then you peel a little bit of the backing away, with the backing facing the window, press a starting point of the film to the window, then with a squeegee, start smoothly pressing the film to the window slowly as you slowly peel the backing downward, in tandem with squeegeeing the film to the window as you go. If it creases, no big deal. Just pull it back off the window past the crease point and continue on. It's not very hard. just takes patience. The kind you'll want, though, the mirrored backing (since it's the clearest from inside looking out) is also the most difficult to work with. Naturally! And do NOT do it on a breezy or windy day!

I agree with sallymo that fabric treatment probably would be the best choice for you. Mounting blinds above the arch would not look good. Blinds are good for light control and insulation. But they don't look as nice as fabric treatment. If these windows are not in your bedroom, you don't have to worry too much about covering them up with blinds. Ceiling to floor curtains look formal and can also provide light control and insulation when you close them. I have arched windows in my living room and dinning room. I have a layer of sheer fabric inside my curtains and I leave the sheer closed all the time for privacy and keep the heavy weight curtains open. If you want to mount the blinds above the arch, you need to cover the blinds with some top treatment at least.

I would put a simple window film on the arched window. It will give you enough privacy, light coming through, and cover the bad view. You can use a slightly frosted one, or maybe one that looks like seeded glass to match the style of your home. There are los of options. For the square window, you can use a woven wood shade or other blind. For interior mount, you need to measure using the larger outside frame and look for one that will work with the narrow dimension for installation. I think it would be best to mount a roman shade over the window at the ceiling. Then you get the most light while the shade is up and don't have to drill into the beautiful wood frame. You could also mount a rod above the window and use a simple linen drape on each side to pull closed when you want privacy.
