Review on Coavas One Way Window Film: Sun Blocking 23.6 x 78.7 Inches Non-Adhesive Window Tint for Heat Control, Glare Reduction, and UV Protection - Perfect for Home and Office, Removable and Static Cling, Black by Lori Lopez

This solar film is perfect for my office window. Before the installation I could feel heat coming out of the window and I had to close the blinds and draw the curtains to avoid getting burned and blinded by the morning sun. Now that I have this film in place I can leave the blinds open to see what's going on outside and even the window sill stays cool. Actually it was amazing. Installation was easy. You must start with perfectly clean glass and then spray liberally with water on both the window and the side of the film you are applying to the window. I used a credit card wrapped in microfiber cloth as a squeegee to squeeze out any bubbles. Worked great Photos from the window in direct sunlight.
