When your windows show signs of needing an upgrade, investing in replacements that offer durability, efficiency, and long-term value is simply smart. Since 2006, we have been the exclusive distributor and authorized contractor for Infinity From Marvin Windows in the St. Louis area, ensuring Defiance homeowners receive industry-leading performance.
Why Choose Infinity from Marvin Windows:
- Unmatched Durability: Crafted from Ultrex fiberglass, this material is eight times stronger than vinyl and nearly three times stronger than wood-vinyl composites, guaranteeing a lifetime of performance.
- Effortless Maintenance: Enjoy easy-to-clean windows, with styles designed to make upkeep a breeze.
- Customizable Aesthetics: Choose from a wide selection of exterior and interior colors and finishes, including EverWood®, an engineered wood grain interior that looks, feels, and stains like natural wood, offering the reliable performance of Ultrex fiberglass. There are numerous window styles available, including double-hung, casement, sliding, bay, bow windows, and more!
All our windows meet strict ENERGY STAR® ratings, too! We even utilize warm-edged spacers to minimize heat transfer and reduce condensation, boosting your home’s thermal performance and saving you money.
Double-Hung Windows
Versatile and functional, double hung windows feature two operable sashes that tilt in for easy cleaning and customizable ventilation.
Casement Windows
Hinged at the side, casement windows swing open like a door to provide excellent ventilation and unobstructed views.
Picture Windows
Picture windows are large, fixed-pane windows designed to maximize views and natural light. Since they don’t open, they provide superior insulation and are among the most energy-efficient options available.
ProVia exterior replacement doors
While our windows are remarkable, our dedication to your home’s improvement doesn’t stop there. We provide custom-crafted ProVia exterior replacement doors. These doors are meticulously engineered to deliver outstanding energy efficiency, comfort, and security, making your entire home safer and more inviting.
