Is window film/liner worth it?
I’ve seen some window film advertised as saving energy on heating and cooling costs. I’m interested but also concerned about what it will do to all my plants I’m trying to grow for “green” air purifying. We have double pane windows, but a big south facing (with no shade yet) bay window, plus several south and west facing bedroom windows with no real shade. I like daylight and want the blinds open. So how do I know if 1. my plants will survive and 2. the energy savings will pay back on the cost of the window film.
