" Let me start by saying this entire system is from 1970 and was more than likely never serviced by a professional. " It's time to call a professional. If you don't like the quote, get another. It may also be time to replace it.

jlvc, we have two smaller individual screens. A few years prior to getting this screen fabric, my husband had installed all new windows with the type that fold down for easy cleaning. These new windows had one screen in a frame that covered half of the window. He took each framed screen, to a local glass company that also made replacement glass for broken window panes. They removed each screen from the frame and then placed the new screen in the old frame. My husband wanted the full window covered with screen so he also had that glass company make another framed screen for each window, so that each window had full screen coverage. In other words, we have two have screens on each window that look like one whole framed screen. The window company did the installation. My husband said to Google a company called Quality Screen and the screen material is called Solar Screen Fabric. This company's web site explains how the screening material works. We did not order from this company but they offer the product and have a good explanation. Looking in or out the window, these screens look like normal screening. To me the mesh work appears closer and darker than the usual window screen but the view looking out is not obscured. In the daylight, the outside world cannot see in. At night with a light on inside the room, you can see in but not near as much as with regular screening.
