Custom & Commercial Auto Glass in Superior, WI
If it rolls, we glass it.
Back windows, door glass, semi tractors, farm and construction equipment, commercial fleets, and the classic in your garage. Odd shapes and hard-to-find glass since 1933.

The glass the chains won’t touch.
National glass chains are set up for one thing: passenger car windshields. The Twin Ports runs on more than passenger cars. Grain trucks, log trucks, loaders, combines, delivery fleets, and half a century of classics that never came with a part number a call center can look up.
This is the work SGI grew up on. We source, cut, and set glass for equipment other shops turn away, and we keep fleets moving with mobile service to your yard.
- Back glass, door glass, vent and quarter glass
- Semi tractors, box trucks, and trailer cabs
- Farm, construction, and heavy equipment
- Classic and vintage vehicles, sourced with patience
