Since 1983 we have been setting the standard for windows in all forms of racing, from drag racing to stock cars.  

Owner Bob Mayerle was drag racing a Super Gas 1955 Chevy, the Peppermint Twist.  After years of modifications trying to squeeze more performance out of his car, he found himself in search of lighter replacement windows to reduce its overall weight. Back then, acrylic and Plexiglas^® were the only options available. These didn't provide the safety or durability from scratches that a racer needs. No supplier had yet developed the technology to make a safe, lightweight and optically superior molded window Mayerle was looking for.

Mayerle began searching for alternatives. General Electric^® had been producing sheet stock Lexan^® for many years but nobody was using this to mold windows to OEM sizes. Armed with a makeshift oven and the original glass windows from his 1955 Chevy Bel-Air, Mayerle set out to create a set of Lexan^® windows for his car, The Peppermint Twist.

After months of experimentation, Mayerle produced his first set of shatterproof, optically superior preformed Lexan^® windows. He installed them in his car and started making passes at the race track. The response from his fellow racers was overwhelming: people simply could not believe his windows were only 50% of the weight of glass and also shatterproof! This safety aspect meant that there was no danger of the window shattering into shards that could seriously injure the driver. Mayerle soon learned there was a strong market for his windows and Pro Glass was born.  

Since those early days the Mayerle family at Pro Glass has been driven to provide the highest quality preformed Lexan^® windows available on the market. Thousands have chosen Pro Glass windows for their race cars, from just about every professional race team to the local drag racer just starting out. Pro Glass is the choice of Champions all over the world!  The difference is clear, go with the Pro!
