Why Marvin Windows Excel in Minnesota
As a Minnesota-based manufacturer, Marvin understands our climate better than any window company. Their Ultrex fiberglass material is 8x stronger than vinyl and maintains its dimensional stability across temperature ranges from -40°F to 180°F — critical for Minnesota's 130+ degree annual temperature swing.
Ultrex fiberglass will never warp, crack, pit, corrode, or swell regardless of how extreme conditions get. Unlike vinyl, which becomes brittle in cold and soft in heat, Ultrex maintains consistent performance year after year. The material is also paintable, allowing unlimited exterior color choices with a finish that lasts significantly longer than painted vinyl or aluminum cladding.
Marvin's factory in Warroad, Minnesota tests windows in conditions that mirror our actual climate, ensuring real-world performance that meets or exceeds their published specifications.
Marvin Warranty and Quality Assurance
Marvin offers a limited lifetime warranty on their windows, covering the glass, frame, hardware, and finish against manufacturing defects. When professionally installed by a certified installer like Weatherguard Construction, you also receive our workmanship warranty covering proper installation, sealing, and flashing.
Marvin's warranty is backed by a company with over 100 years of window-making experience and a reputation for standing behind their products. Their customer service team is based in the United States and provides responsive support for any warranty questions or claims.
Marvin Energy Performance for Minnesota Homes
Marvin windows are engineered for exceptional energy performance in cold climates. Their Ultrex fiberglass frames have a thermal expansion rate nearly identical to glass, which means the seal between frame and glass stays tight through Minnesota's dramatic temperature swings — a critical advantage that prevents air infiltration and condensation problems.
Marvin offers multiple glass packages optimized for northern climates, including triple-pane options with dual Low-E coatings, argon or krypton gas fills, and warm-edge spacer systems. These high-performance glass packages achieve U-factors as low as 0.18, making them among the most energy-efficient windows available for Minnesota homes. Homeowners upgrading from older windows can expect heating cost reductions of 20-35% depending on the number of windows replaced.
Every Marvin window installed by Weatherguard is ENERGY STAR certified for the Northern climate zone. Our full-frame installation method maximizes the thermal envelope by eliminating air gaps and ensuring continuous insulation around every opening.
The Weatherguard Marvin Installation Process
Installing Marvin windows requires precision and craftsmanship that matches the quality of the product itself. Weatherguard's installation process begins with a detailed in-home measurement appointment where we assess every window opening, discuss your aesthetic preferences and performance goals, and help you navigate Marvin's extensive configuration options.
Because Marvin windows are built to order, the manufacturing lead time is typically 6-10 weeks. During this period, our team prepares all project logistics and coordinates with you on scheduling. When your windows arrive, our factory-trained crew completes a thorough inspection of every unit before installation begins.
Our full-frame installation removes the entire existing window assembly, allowing us to inspect and repair rough opening framing, apply peel-and-stick waterproof membrane, and install each new Marvin window with meticulous attention to level, plumb, and square. We seal every window with low-expansion foam insulation and apply interior and exterior trim to create a finished, weather-tight installation. Each window is tested for smooth operation and proper locking before we move to the next.
