Is this forum still in existence? I was thinking of using 20mil clear vinyl sheeting as a glazing for a polyisocyanurate box with two layers of fiberglass screen inside on a polyisocyanurate frame. That would be extremely light weight. It could all be put together with foil tape. The clear vinyl sheeting withstands up to 160 degrees f supposedly.

If you can find ETFE (
Ethylene Tetrafluoroethylene) that will handle much higher temperatures (200 degC). Other attributes: its immune to UV and will last for at least 25 years. Its non-stick/self cleaning and very tough so you can get by with a 60-100 micron film thickness.

Welcome! Vinyl sheeting will not only off-gas for quite some time, but it can yellow and will become brittle over time. I wonder if you could apply Armor-All to the exterior? It supposedly has UV protectants and would have to be reapplied seasonally. Yes, this forum is alive and well since Scott brought it came over from Yahoo 4 years ago. Admittedly, the activity is seasonal in nature, but with the first sign of cold weather, activity picks up quite a bit. Many new members signed up in the last month alone. Greg in MN
