In this post—part two of a multi-part series—we will explore and compare two popular window framing materials, aluminum and fiberglass. Aluminum windows have been a popular choice since the 1960s and remain a popular choice today. Fiberglass windows, on the other hand, are relatively new to the market on a large scale.


If you missed part one—Fiberglass vs. Wood Windows—be sure to check it out for a short comparison of how fiberglass and wood windows compare when it comes to aesthetics, energy efficiency, and maintenance requirements!


Aluminum vs. Fiberglass Windows – Aesthetics

Aluminum windows have a wide range of aesthetic looks. From basic aluminum frames to intricate historically accurate replacement windows, aluminum windows can meet a variety of aesthetic needs. At Weather Shield, we offer two aluminum window lines—the Signature Series and the Premium Series. Both lines of Weather Shield aluminum windows offer extruded aluminum-clad exteriors with real milled wood interiors.


Our fiberglass window products offer homeowners a beautiful window replacement product with dozens of potential design options—sure to meet any need.


For homeowners who want only the best in aesthetic value, however, we recommend the Weather Shield Premium Series™. The Premium Series is designed to meet the needs of the most discriminating architects and homeowners. This product line represents our most extensive collection of aluminum-clad windows with almost limitless design combinations!


Aluminum vs. Fiberglass Windows – Maintenance

Both aluminum and fiberglass windows are noted for their strength, durability, and low maintenance. There are no significant differences in maintenance requirements between the two materials. Both aluminum and fiberglass windows can retain their like-new appearance for years to come with a simple cleaning.


Over time, aluminum frames can be susceptible to corrosion if you live in coastal environments, but this risk can be mitigated if your windows are well maintained and are coated in a corrosion-resistant paint.  Fiberglass has a distinct advantage when it comes to coastal salt-water corrosion.  The fiberglass cladding is resistant to this corrison.


Aluminum vs. Fiberglass Windows – Energy Efficiency

One of the major drawbacks that aluminum windows have always had versus their counterparts has been energy efficiency. As you know, metal is a great conductor of temperature—which is a detriment to energy efficiency. Although today’s aluminum windows incorporate a number of energy efficient features like low-e glass, multiple panes of insulated glass, and warm edge spacers, fiberglass windows with comparable features will provide greater energy efficiency. Fiberglass is an exceptional insulating material and is virtually unaffected by temperature extremes like other window materials.


Although Weather Shield windows from all product lines offer some of the best energy efficiency ratings in the industry, for consumers looking for the absolute best in energy efficiency, fiberglass windows are an excellent choice.


As we mentioned in the previous blog post, the most important thing to keep in mind when shopping for energy efficient windows is that windows are only as efficient as their installation. Even the most energy efficient windows will provide you with little value if they are poorly installed. If you are considering a window replacement project, contact a Weather Shield dealer in your area. They will help you pick the best window for your home and needs and provide a high-quality installation that makes the most of your investment.
