I have a sunroom the lower windows were replaced and upper very high shaped windows were not replaced but we added window film kit to each one. We washed the windows first then added a dark tinted film that is cut to fit inside the window area using razor knife, a soapy water spray bottle and a squeegee. After the tint was done we used the double sided tape around the trim edges and applied the thin film(plastic). Took a blow dryer and went over the film and it shrank up pulling very tight. Took razor knife and trimmed the edges. The difference in temperature was noticeable right away.
