Attached is an image of my greenhouse back in October 2007 when I was washing the roof, pre-winter. I have speculated about creating removable shade cloth units such as I have for the rest of the roof but cannot visualize how to fit around the wax filled cylinders that open / close the vents in response to temperature. I think either of the two very thoughtful suggestions would be awkward to implement. I don't think laying belly down on the slanting garage roof and attempting to neatly apply greenhouse paint to the roof vents is a feasible option. Also, I've seen the greenhouse paint used on glass, but don't know if it is suitable for polycarbonate twin wall. If shade cloth is, with some difficulty, glued to the interior of the roof vents how would it be removed in winter. Keep the ideas coming - sooner or later there will be an Aha! moment and I'll learn the answer. Judy On 1/9/2021 11:31 AM, The Silent Seed via pbs wrote: > R Hansen - genius - painted on.
