If you're shopping for Marvin windows in Denver, you've probably encountered two prominent product lines: Marvin Ultimate and Infinity from Marvin. While both carry the respected Marvin name, these are fundamentally different products designed for different homeowners and budgets.
The confusion is understandable—and intentional. Many window companies aggressively market Infinity as if it's Marvin's flagship product, when in reality, Marvin Ultimate represents the company's premium clad-wood line with superior materials, longer warranties, and unlimited customization options.
If you're investing in windows for your forever home in Colorado, understanding these differences could save you thousands in long-term costs and ensure you get the performance you need for our challenging climate.
Marvin Ultimate: The Premium Clad-Wood Line
What It Is: Marvin Ultimate represents Marvin's flagship window series, featuring real wood interiors with extruded aluminum exteriors. This is true clad-wood construction designed for homeowners who want the best of both worlds: authentic wood beauty inside with maximum weather protection outside.
Key Features:
● Real Wood Interiors: Choose from multiple wood species that can be stained, painted, and refinished
● Extruded Aluminum Cladding: Commercial-grade exterior finish with 20-year warranty
● Unlimited Customization: Nearly any size, shape, or configuration imaginable
● Superior Hardware: Heavy-duty components designed for large, architectural windows
● Refinishable: Interior wood can be sanded and refinished if damaged
Infinity from Marvin: The Fiberglass Replacement Line
What It Is: Infinity is Marvin's fiberglass window brand, featuring Ultrex® fiberglass frames with acrylic cap finishes. It's positioned as a lower-maintenance alternative to wood, primarily targeting the replacement window market.
Key Features:
● Ultrex® Fiberglass: Structural fiberglass frames with acrylic exterior finish
● EverWood® Interior: Simulated wood surface that accepts stain and paint
● 10-Year Finish Warranty: Limited warranty coverage on exterior finish
● Standard Sizes: More limited customization options compared to Ultimate
● Non-Refinishable: Interior cannot be truly refinished like real wood
The Real Differences That Matter
Material Quality: Real Wood vs. Simulated Wood
Ultimate: Features genuine wood interiors that provide authentic grain patterns, natural insulation properties, and the ability to be refinished multiple times over the window's lifespan. If scratched or damaged, the wood can be sanded smooth and refinished to look like new.
Infinity: Uses EverWood®, a composite surface designed to mimic wood appearance. While it accepts stain and paint, it's not real wood and cannot be refinished in the traditional sense. Damage often results in visible repairs that don't blend seamlessly.
Exterior Durability: Extruded Aluminum vs. Acrylic Fiberglass
Ultimate: Extruded aluminum cladding provides superior protection against hail, UV exposure, and temperature extremes. The commercial-grade finish is baked on and backed by a 20-year warranty against fading, chalking, and peeling.
Infinity: Acrylic-capped fiberglass offers good performance but with limitations. The acrylic finish can be more prone to chalking and fading over time, particularly in high-UV environments like Colorado. Warranty coverage is typically 10 years.
Customization: Unlimited vs. Limited Options
Ultimate: Offers virtually unlimited design possibilities. Custom sizes, unique shapes, specialty glass options, and architectural details are all possible. This flexibility makes Ultimate ideal for historic renovations, luxury homes, and unique architectural styles.
Infinity:
Provides good options within standard sizing and configurations but is more limited for custom applications. The focus is on efficient replacement of existing windows rather than architectural creativity.
Real-World Performance in Colorado
The John Anderson Project
Recently, we worked with a homeowner in Cherry Hills Village who was deciding between Ultimate and Infinity for their 1980s contemporary home. The house featured large, geometric windows that required custom sizing—something that immediately pointed toward Ultimate.
However, the deciding factor came down to longevity. When they calculated the cost difference over 20 years, including potential refinishing and warranty coverage, Ultimate actually provided better value despite the higher upfront investment.
Three years later, their windows have weathered two significant hailstorms without damage, while neighbors with acrylic-finished windows needed repairs.
Colorado Climate Considerations
Hail Resistance: Colorado's severe weather makes exterior durability crucial. Extruded aluminum cladding typically withstands hail impact better than acrylic finishes.
UV Protection: At mile-high altitudes, UV exposure is 25% more intense than at sea level. Materials with 20-year UV warranties provide better long-term value than those with 10-year coverage.
Temperature Swings:
Daily temperature variations can exceed 40 degrees. Real wood with aluminum protection handles these swings better than composite materials.
The Year-11 Problem
Here's something most homeowners don't consider: What happens after the warranty expires?
With Infinity's 10-year finish warranty, you're potentially facing refinishing costs in year 11—assuming the acrylic finish can be successfully refinished. Many acrylic finishes cannot be easily touched up or repainted, potentially requiring full window replacement.
Ultimate's 20-year warranty provides an additional decade of protection. Even beyond that, the extruded aluminum cladding can often be refinished or repainted using standard techniques, extending the window's life even further.
Investment Comparison: Total Cost of Ownership
While Ultimate commands a premium upfront, consider the total investment:
Infinity Total Costs:
● Initial purchase price
● Potential refinishing after year 10
● Limited repair options for interior damage
● Lower impact on home resale value
Ultimate Total Costs:
● Higher initial investment
● 20-year exterior warranty coverage
● Refinishable interior for long-term beauty
● Significant positive impact on home value
When amortized over 20+ years, the cost difference often becomes negligible—while the performance and aesthetic advantages remain significant.
