Infinity from Marvin Windows: Appearance, Design & Performance

When we talk about Infinity Windows appearance and design, it invokes a recognition and appreciation of the level of craftsmanship and precision associated with its development. From aesthetics to operation, each advanced feature engineered into the product helps make Infinity different and better than other replacement windows.

What Makes Infinity Windows from Marvin Different

Traditional Profiles and Appearance — Infinity windows are designed by the wood window experts at Marvin Windows and Doors to have all the traditional beauty of wood windows, without the maintenance. Marvin has over 70 years of experience making beautiful, innovative window and door products.

• Modern glazing often lacks charm. Infinity windows replicate the historical putty-glazed look—ideal for preservation and authenticity.
• Interior sash edges replicate the refined appearance of routed wood profiles.

Larger Glass Area — Ultrex fiberglass allows for slimmer frames and more glass, which means better views and more daylight in your home.

Thermoset Advantage — Ultrex retains its shape under extreme conditions, unlike vinyl. That means Infinity windows won’t warp, bend, or bow over time.

What You Won’t Find on Infinity Windows — And Why That’s a Good Thing

• No unsightly weep-holes. Infinity integrates drainage into its design.

• Hidden tilt-latches keep the checkrail clean and traditional on Double Hung models.

• Dual locks on small windows? Not here. Infinity uses single, robust zinc hardware for clean lines and high performance.

• Infinity avoids excessive weatherstripping. Other windows rely on bulky strips to make up for poor material expansion and performance.

Infinity from Marvin was founded on a promise: delivering a fiberglass window replacement experience that consistently exceeds your expectations. The attention to detail in every Infinity window allows Gravina's Window Center of Littleton to complement your home's style inside and out.
