Noticeable difference in temperature for any sun-facing windows
How easy are they to cut to size, or if you need to use multiple to cover a window how does the gap/seam look? Have been thinking of getting them, but we also want to replace our windows at some point. I assume you can’t just reuse them?
At least in home depot, some of them come with a specific blade tool, or one that’s not too much more expensive. It’s hard/sharp enough to seamlessly cut through the tints, but not scratch your window.
