Aluminum is the strongest common window frame material, which is why it holds narrow sightlines at sizes where fiberglass or vinyl need noticeably heavier profiles. On a wall of glass or a large picture unit, that difference is visible from across the room.

Our extensive selection of aluminum replacement windows, sourced from renowned manufacturers like Marvin and Pella, offers numerous advantages:
Engineered with advanced features, our aluminum windows minimize heat transfer, potentially reducing your energy consumption and costs.
The highest structural strength of any common window frame material, which matters most on large openings and exposed elevations.
Enjoy windows that stay looking good with minimal upkeep, for years to come.
Aluminum conducts heat more readily than fiberglass, vinyl, or wood. Thermally broken frames address it directly by placing an insulating barrier inside the frame that interrupts the path heat would otherwise take straight through the metal, improving the U-factor substantially over standard aluminum.
We will show you the NFRC-certified U-factor for the aluminum configuration alongside the fiberglass and vinyl equivalents, so you can weigh the trade-off against your openings and your budget rather than take our word for it.
With over two decades of experience, our team at GS Exterior Experts is equipped to handle projects of any scale. We're dedicated to transforming your renovation aspirations into reality, ensuring your vision comes to life seamlessly.
Discover stunning finishes that seamlessly complement other metallic accents within your interior. Combine casement and floor-to-ceiling windows for a truly modern aesthetic.

Yes, typically. Aluminum windows generally cost 30 to 50 percent more than standard vinyl due to material costs and the engineering required for thermal breaks.
No, aluminum doesn’t rust. Quality frames use anodized or powder-coated finishes to prevent corrosion, even in harsher environments.
Older or non-thermally-broken aluminum windows conduct heat readily and perform worse than vinyl or fiberglass. Modern aluminum windows with thermal breaks close much of that gap, but aluminum still generally isn’t the top performer for insulation.
It can happen on non-insulated aluminum frames when there’s a significant indoor and outdoor temperature difference. A proper thermal break design largely prevents this.
Yes. Aluminum’s structural strength allows for slimmer frames and larger glass areas than most other materials support, which is one of its main advantages.
