We have UV film on some of the other windows in the house, and it does a great job of keeping things cooler. From what I've read, UV film doesn't harm houseplants because plants don't use UV light, but I'm not sure if it's the same for carnivores. The only thing I could find online about CPs and UV light is an article about how some pitcher plants have rims that glow under UV light to help them attract insects, which is cool, but didn't really answer my question.
