What percent of UV is blocked?

Hello, Thanks for interesting in our film. Here are the UV rejection of all of our four colors. 1. Black-silver: Blocks up to 91% of UV rays 2. Tea-silver: Blocks up to 89% of UV rays 3. Blue-silver: Blocks up to 87% of UV rays 4. Silver: Blocks up to 71% of UV rays

Is this the type of film that reverses effect at night? (Brightest side gets the privacy/mirror effect)

AFAIK, this is the way all films work and there is no film that works otherwise. It has to do with which side is getting the light. If you are looking for privacy and UV/IR reduction, consider adding a Frosted/Wavy/Tulip type film with this film on the inside. People on the outside will see the image distorting film (as many windows high as desired) and you will have the UV/IR protection. There may be UV/IR blocking films with frosting already on them, I have not looked.

Does it really cool down the room inside?

Thanks for your question. This one way window film can blocking out most of the solar rays by reflecting it away from the window, which can keep cool in summer, but please do not expect it can worked as an air conditioner to make your room very cooler. Hope this would help you.

So does the reverse effect mean that at night from the inside your windows will look like a mirror?

Thank you for interested in our one way window film, the film of you asked is that will shows the mirrored view only in daytime, if at the night, then the mirrored view will disappear.
