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.

Simulated Putty Glazing
Simulated Traditional Glazing
  • 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.

Larger Glass Area


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.

Poor Design With Weep Holes

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

Unsightly Tilt Latches

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

Why Two Locks

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

Crappy Vinyl Windows


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.
