Aluminum Windows: Your Guide

It’s hard to go wrong with an aluminum window. It is more affordable than the timbre, uPVC, or fiberglass ones, yet way more sturdy and low-maintenance. Anticorrosive aluminum alloys last for decades, and you can tailor the design of your dreams choosing from a plethora of frame options. 

Advantages of aluminum window frames

  • Aluminum windows resist rusting, peeling, warping, or bending. They will last 45-50 years, and some brands offer lifetime warranty. 
  • They also resist the impact of weather and elements, which make them ideal for regions with frequent storms, rains, and extreme temperatures. 
  • Remarkable thermal and sound insulation options. 
  • Aluminum frames come in almost every window configuration, shape, and size imaginable. They also have a non-bulky, sleek look that goes well with every interior, and can be tweaked with different interior and exterior veneers, finishes, and hardware. 
  • Despite their toughness, aluminum frames are easy to operate and clean. 
  • They make a safe first-floor option: not only are the aluminum frames durable, but they also support different state-of-the-art locking systems.

    Repair or replacement: what to choose with aluminum windows?

    Whether you should repair a faulty/old aluminum window, or just get a new one, depends on several factors. 

    Repair if

    • Your aluminum window is double- or triple-paned;
    • The glass is broken or cracked;
    • Sashes keep getting jammed or stuck;
    • Exterior casings are damaged;
    • The drip cap is missing; 
    • There’s a minor water leakage due to drainage system problems.

    Replace if

    • Your aluminum window is just single-paned. If it has already started to require work, replacing it altogether with double or triple-paned aluminum options will save you continuous repairs in the long run; 
    • There are structural problems with either the existent window or the wall/opening; 
    • The window gets foggy constantly; 
    • There’s excessive water leakage.
