Benefits of Aluminum Windows
Aluminum windows are a great low-maintenance option and don’t require the care that wood does. They usually have an anodized finish applied at the factory so that they won’t corrode.
They’re very strong despite also being lightweight which makes them easy to install properly. Aluminum windows have fantastic durability and they can last up to 50 years.
The aluminum material offers lots of flexibility and it’s easy to manipulate. So, aluminum windows are a smart choice if you have openings with unique shapes.
They have narrow frames that don’t take away from the views outside. They provide a sleek look and often cost less than both wood and fiberglass options.
Drawbacks of Aluminum Windows
Unfortunately, Aluminum won’t keep your home insulated as well as other options. Homeowners typically use weather strips and other thermal products on their aluminum windows to help keep the heat in.
Condensation can build up inside aluminum windows and lead to expensive repairs. The moisture problem can be solved by placing non-conductive material between the panes, but it’s an additional cost.
Benefits of Fiberglass Windows
High temperatures won’t shrink, swell, or sag fiberglass windows. This ensures a tight seal for your window’s edges to prevent leaks.
Fiberglass is also waterproof so there are no issues with moisture causing rot, swelling, or mold growth. The frames are seamless so they don’t collect debris.
You don’t need as much material for fiberglass windows because of their advanced strength. That means narrower frames and more glass for better views and more sunlight.
Fiberglass weaves glass fiber together for reinforcement and it’s much stronger than vinyl. It can withstand high winds, hail, and other impacts.
Most fiberglass windows last 50 years or more and homeowners don’t need to replace them. Their warranties usually last up to 20 years which makes them a very safe investment.
Fiberglass doesnt transfer cold or heat so they don’t expand or contract which makes it an excellent insulator. They’re also more energy efficient because they don’t allow air gaps.
Fiberglass frames come in an impressive variety of styles and colors and you can also paint or stain them. They can also mimic wooden window styles to achieve a classic aesthetic.
Drawbacks of Fiberglass Windows
You won’t typically find fiberglass windows in stores and they’re more expensive than aluminum options. You must also make sure fiberglass windows have a powder coat or they’ll fade from sunlight over time.
They’re more rigid than other window types which makes them more difficult to install. You’ll need to hire professionals to install them and fiberglass companies might be hard to find in your area. You can learn more here about replacements and installations.
