Thermo-Tech's patio doors come in two styles: French Style, with wider panel rails for a traditional hinged-door look in a sliding operation, and Slim Line, with narrow rails that maximize glass and view.
Both are engineered for durability and energy efficiency in the climate they're built in — insulated glass packages, robust rollers, and made-to-order sizing for replacement or new construction.
Highlights
- French Style and Slim Line design options
- Energy packages built for northern winters
- Made-to-order sizing for replacement fits
- Smooth-rolling hardware and secure locking
- Minnesota-made and regionally supported
