Are Fiberglass Windows Good for the Environment?

In addition to finding a window that looks good and performs well, many Bellevue homeowners are also looking for a window option that helps reduce their carbon footprint. According to the American Energy Association, nearly 60% of the energy wasted in American homes escapes through windows and doors. It’s easy to see why this would be a logical place to start when attempting to make your home a little greener. Fiberglass windows hold one of the strongest reputations for energy efficiency on the market, but you still may be wondering how they measure up to other popular window materials like wood, vinyl and aluminum. Let’s take a closer look at these comparisons to see if fiberglass windows really are the best option for environmentally friendly windows.

Fiberglass Windows vs. Wood Windows

When it comes to the energy efficiency of wood windows, their material comes with one major design flaw. Wood windows have the tendency to absorb excess moisture, which results in weather damage like warping, rotting or distorting of the frame. This weather damage quickly leads to gaps and drafts that allow your heating and cooling efforts to go out the window. Fortunately, while fiberglass windows may look exactly like wood windows, they never actually absorb moisture. This means a drastically reduced chance of weather damage and quality insulation.

Fiberglass Windows vs. Aluminum Windows

Much like wood windows, aluminum windows Achilles heel is found in their nature. Aluminum windows are strong, lightweight, and easy to work with. Unfortunately, their metal material also means they absorb and hold onto excess heat. This means more energy will need to be spent during the warmer seasons to keep your home comfortable. Fiberglass windows are also durable, however they don’t hold excess heat making it easy to keep your home at the temperature you want it to be all year round.

Fiberglass Windows vs. Vinyl Windows

Vinyl windows have come a long way and have also earned an impressive reputation for their energy efficient features. However, some of the features may not be as beneficial in the long run as they appear. For example, one of vinyl windows most noted features is the fact that they expand to create a snugger fit and enhance insulation. Unfortunately, vinyl windows expand at a rate 4x’s faster than their glass, which often causes extra pressure to be placed on the windows that can result in the formation of drafts. Fiberglass windows also have the ability to expand, however, they expand at a rate equal to the glass to avoid any future problems from arising.

While each material plays its own role in energy efficiency, it’s safe to say that fiberglass windows are the most energy efficient option on the market. At Signature Windows, you’ll find the finest selection of energy efficient fiberglass windows in Bellevue, WA to choose from.
