I contacted A-1 Glass coating as a certified installer for Vista Window Film. The Vista product they install and promote is the industry leader in window films and is used and aproved by the design trade in residential and commercial spaces to block ultraviolet rays (stops fading), solar energy (reduces heat build up), and provide optical clarity (eliminates glare). My experiences with A-1 in this capacity has been excellent. My client feedback is 100% positive and their performance reinforces my clients' trust in my choices. Five stars!
