Review on 🪞 Enhance Privacy and Comfort with One Way Mirror Window Film: Daytime Privacy, Heat Control, Anti-UV, Decorative, Non-Adhesive, Suitable for Home and Office, Black Silver, 6 Mil, 17.7 Inch x 6.5 Feet by Nicole Bryant

This material is great if you are looking for something to reduce heat. Our house is older and the air conditioning upstairs just doesn't do its job; after application, the difference is noticeable and even the parts inside where the sun shines directly no longer feel warm. As far as application goes, I read the reviews and here are the top tips: Before applying, trim the film a little more than you need; I used a separate window pane as a template. Clean the window before use; is it important. Wet the window well with soapy water, then remove the protective film and place the film where you want it. It's time to move and adjust so that the entire window is covered. Spray the applied film with soapy water and use a squeegee to squeeze out any bubbles; Thanks to the additional amount of soapy water, the squeegee glides smoothly over the film. Cut with a utility knife, then go over again with a squeegee and wipe away any excess soapy water. They pop open quickly once you get the hang of it and stick perfectly even when I open the windows (which are cased so they're fully protected from the wind and weather when open). Highly recommended!
