Since I don't run into no-see-ums too often, and since the screening that keeps them out makes for quite a bit less airflow compared to a regular screen, I'm going to try a temporary installation. That is, I'm going to keep the regular screen on the
windows, and then simply add no-see-um netting when I need it.
I happened to have an old tent with no-see-um netting
windows that I salvaged prior to jettisoning the tent, but you can also buy the netting new.
I cut panels of the netting that were a few inches larger all-around than my
windows, then made a length of shock cord into a loop with a diameter somewhat smaller than the overall size of the window frame. My plan is to spread the netting out across the window, on the inside, then put the "ring" of shock cord around the frame, thereby stretching the netting taught and holding it in place. Something like an embroidery hoop wherein the netting is the fabric and the window frame and the shock cord are the "hoops."
If this works well, I may permanently sew the shock cord into channels I sew into the netting, something like a big shower cap.
Note that I happen to have the square cornered
jalousie windows in my
Boler, and they protrude an inch or so into the camper, so I have a lip to work with.
I'll probably try it out later this week, as the no-see-ums are out.
