I have a large porch on the back of the house and three years my wife decided to enclose it, making it a screened-in porch. If there is a single mosquito in the neighborhood, it will find her! Therefore, screening it in would allow her to spend some time "out-doors". The following year I decided to have the porch screening covered with removable, clear, marine-vinyl panels. There are three 4.5'x6.5' panels on each side and then one to cover the screening above the double doors. I can put up these panels in November and then take them down and store them when it gets warmer in the spring.
The problem is that these vinyl panels have pretty much no insulation value. The wind is certainly blocked but not the cold. Therefore I run two electric heaters, 1500 W each, to keep the porch above 55 F. My thought is to get some more solar blanket material, and cut it into three pieces. Two would cover the sides (13.5'x6.5') and one would cover the transom above the doors. I would mount the two side panels on windup rollers and screw in the transom panel. With the rollers I could raise the material when the weather is mild and lower it when it is cold. I would stretch aluminum wire across the two side panels to keep the material from flapping in the wind and also to snug it to the vinyl covering. This is what I did with the solar blanket material covering my two GH's. I would probably not cover the two, 3' doors, which are aluminum with double-pane windows.
Just a thought right now but perhaps workable. I hope the cost of the material and rollers will quickly be off-set by reduced electric usage.
