Benefits of Aluminum Replacement Windows

Some of our residential clients have asked about replacing their existing aluminum windows with new aluminum windows. You may ask, “why they don’t opt to upgrade to newer Fiberglass or Vinyl materials which tend to offer higher efficiency and endurance?” The answer is typically that these homeowners are seeking to maintain the contemporary look of their home. Another reason is that aluminum windows often have thinner frames that maximize viewing area, and with silver (anodized aluminum) or dark bronze frames, they provide a modern and commercial character to a building.

Like vinyl windows, aluminum windows have been considerably improved over the years. Some replacement aluminum window improvements:

  • Have deeper frames
  • Offer higher-performing glass packages, and
  • Are built with thermal-break barriers – reduces temperature change, which improves energy efficiency & reduces “sweating” on the frames

Pros of aluminum windows:

  • Low cost
  • Low maintenance
  • Durable
  • High visibility (thin lines)
  • The style/color may match your existing home layout (some homeowners prefer the ‘modern’ look of aluminum)
  • Good noise insulation

Cons of Aluminum Windows

Those are good pros of aluminum frame windows, so what are the cons? Cons of aluminum windows:

  • Best for warm climate – easily conducts heat and cold so they have a high U-value, which means they aren’t the most energy efficient product
  • Get cold very easily – feel cold to the touch, and lose heat
  • Must have thermal break in frame – a strip of rubber or plastic

Reasons why you might consider switching to Fiberglass or Vinyl Windows:

  • Aluminum is less energy efficient (which increases heating and cooling costs)
  • Aluminum is more prone to condensation problems in high moisture areas
  • Aluminum may eventually oxidize and rust in mid to highly corrosive zones
