Built for Colorado’s Climate
Unlike vinyl patio doors that can warp, expand, or become brittle over time, Infinity® by Marvin® sliding patio doors are built from proprietary Ultrex® fiberglass, engineered to handle Colorado’s intense sun, high elevation, and extreme temperature swings.
Fiberglass expands and contracts at nearly the same rate as glass, which helps maintain tight seals, smooth operation, and long-term energy efficiency year after year.
Energy Efficiency & Glass Options
Infinity sliding patio doors offer a range of advanced glass packages designed to improve comfort, reduce energy loss, and protect your home from UV damage.
- Double-pane insulating glass for year-round efficiency
- Low-E glass coatings to reflect heat and harmful UV rays
- Optional grilles between the glass or simulated divided lites for architectural detail
- Screen door options available for ventilation and insect protection

- Exceptional durability with fiberglass frames that won’t warp, crack, or chalk
- Improved energy efficiency for greater indoor comfort
- Smooth, reliable operation designed for daily use
- Professionally installed by experienced local installers
