Thirty years ago, Sun Control had just two part-time window-tint installers. Today, they're 15 strong?each certified to install window films not just in cars, but also in homes and commercial locations. They also benefit interiors by keeping them cool on hot summer days and filtering out damaging UV rays that can fade upholstery. For homes, tinting reduces heating and cooling costs and decreases glare while still allowing in natural light. To ensure proper fit and a seamless look, the 3M certified installers cut films and bless them with a lifetime warranty.
