Welcome to TNT Signature Glass Design, LLC

Protecting your glass one square foot at a time.

TNT Signature Glass Design, is a family owned and operated business, with over 28 years of experience in the window film industry. We are proud to call Wisconsin home, but are willing to travel across the country to install 3M Window films.

We offer the high quality and warranties that come with the 3M brand, but also focus on keeping our customers top priority. We will discuss what films fit your needs and find a solution to ensure you are completely satisfied.


I may sounds like I’m “gushing” but we are truly that satisfied with our window film. No glare, no fading, the AC runs considerably less. It’s worth every penny we paid. We also got a tax credit as well. Our house faces west, and at times, the sun was brutal. Not anymore. You will not be disappointed.

Quality Service, Quality Products

No one has more experience with window films than 3M. In 1966, they received the first patent for window film. For decades, 3M has remained the world leader in the development of new and innovative adhesives and films. Today there are millions of square feet of 3M Window Films installed around the world. With these films, they have once again demonstrated why we are the industry leader.

What good is a 10-year warranty from a company that wasn’t around 10 years from now? Selecting 3M Window Films gives you peace of mind. That’s because they have one of the most comprehensive warranties you can get; backed by a company you know and trust.

There are thousands of window film dealers in the country, but only a select few have been chosen to be part of the 3M Prestige Dealer network. They were selected because of their ability to offer quality work, their extensive product knowledge, and their ability to serve their customers to the highest standards. 3M not only wanted to offer the world’s finest window film, they wanted to be certain they were offered by the world’s leading window film dealers.

TNT Signature Glass Design is proud to be one a certified Prestige Dealer. We strive to not only maintain the level of excellence set by 3M, but surpass it so you are as thrilled with our service as you are with the Prestige Window Film we install.
