Vinyl or Fiberglass Windows?

When remodeling, there are several types of window choices that you can choose from, which can sometimes lead to confusion as to what the best option for you us. Often times, a homeowner’s dilemma is choosing between Vinyl or Fiberglass windows. Though these two types of windows are both popular, there are many differences between the two. Ultimately, it comes down to what is best for you and your needs and carefully considering the pros and cons of each before making your choice. Below, we cover these two types of windows to help you make the best decision.

Vinyl Windows

Vinyl windows are made from extruded polyvinyl chloride (PVC) as the base material. They may also include metal as an internal structural element to stiffen the frames. The primary advantage of vinyl-framed windows is that they are very affordable, costing only about half of what wood-framed windows cost. Despite their affordability, however, they still possess remarkable durability. They are also quite energy efficient, due to the fact that they are fabricated using a honeycomb structure that minimizes thermal transfer. Vinyl windows never need to be painted and are available in colors such as white and various neutral colors. Finally, vinyl windows can be fabricated to fit any opening size.

Fiberglass Windows

Fiberglass, on the other hand, is a frame material known for its premium strength, durability, and performance. Fiberglass windows were originally developed to address certain limitations to vinyl windows. As vinyl ages over time, it slowly begins to lose its resiliency. Fiberglass windows do not have this limitation, considering they are manufactured with a mixture of fiberglass and polyester resins that is stronger than wood. Fiberglass is impervious to water, cold, heat, insects, salt air and ultraviolet rays—all the traditional enemies of windows and doors. Occupying a price range between vinyl and wood, fiberglass-framed windows are an increasingly popular choice.

Below, we breakdown and compare two types of windows based on a variety of different aspects.

Cost

If you’re on a budget, vinyl windows are the way to go. Fiberglass windows are made with higher-quality materials which make them a bit more expensive.

Durability

Vinyl windows rank close together with its fiberglass counterpart for durability because they are both made from inert substances that do not rot and are not tempting to insects. However, Fiberglass windows are more durable structurally and are estimated to have a 38% longer lifespan than vinyl.

Strength

Fiberglass is stronger and has a more rigid frame than vinyl and can support heavy weights and the windows do not warp. However, if the window opening is properly framed, vinyl windows can perform well too.

Appearance

Fiberglass frames has a better appearance than Vinyl. Vinyl windows have an obvious join line at their corners, while fiberglass does not. Fiberglass frames also mimic the look of wooden windows more closely, while vinyl windows are more plain. Fiberglass windows are available in a variety of factory-painted color but their windows are susceptible to peeling, fading and require maintenance while Vinyl windows have a color that goes straight through, and does not require painting or fade in sunlight.

Maintenance

Both types of windows require equally low maintenance. However, both require some basic care over time. Vinyl windows may be marginally easier to repair because the flexibility of the frame means that they are easier to remove and install.

Energy Efficiency

The glass fibers added to a fiberglass window frame mean that the material does not expand and contract and or conduct heat or cold. This means it’s a better insulator than vinyl. A typical vinyl window frame may be foam filled to help with insulation but will lack structural integrity. Because of fiberglass window frames, it makes them one of the best noise insulators available. Vinyl does not have this same insulating property.
