Mr. Tint of America, Northampton

Mr. Tint deploys Formula One window films to keep people safe from heat, solar glare, and UV rays. From the Air Blue series films, whose nano-ceramic technology was designed to not interfere with electronics, to the comfort series, which comes in a rainbow of color options. Each of their tints keeps 99% of UV rays at bay and reduces heat by up to half.

The techs also outfit homes and commercial buildings with the top-shelf Vista window tinting. The film—which can be customized with a corporate logo—forces UV rays to face-plant against window panes rather than ghosting right through them, and blocks almost 80% of solar heat, keeping air conditioning bills down.
