Aluminum Windows

A premium look that's worth understanding before you buy. Here's what aluminum offers, how it compares, and the lines we install across the Bay Area.

The slimmest frames, the most glass

Aluminum gives you the thinnest sightlines and the strength to span big openings — ideal for modern Bay Area homes that want light and a clean look.

  • Slim frames, more glass and light
  • Very strong for large openings
  • Modern, clean look
  • Low maintenance, long-lasting

Common questions

Are aluminum windows energy-efficient?

Modern aluminum uses a thermal break plus Low-E glass to perform well, especially with big glass and slim frames. When you compare, look at the ENERGY STAR rating and the NFRC label.

Why choose aluminum over vinyl?

For the thinnest frames, the most glass, and the strength to span large openings.
