Carbon metal window tint has a very high heat blocking percentage of about 80%, and blocks about 85% of the infra red rays (IR). Its a relatively dark film allowing only about 7% of the light. From the inside of your room looking outside though the tinted glass, the colour is like a sunset. From the outside view during the day, the glass will have a titanium kind of colour. (it's not reflective enough to create a clear mirror image) It's great for daytime privacy and uv protection, however if glare from direct sunlight is an issue, this film might just not meet your needs!
