Are Vinyl Windows Better than Glass Windows?

Vinyl Windows

Windows are an essential part of every home. Windows allow you to see outside of your home, they let in light, and also allow ventilation. Windows can also dramatically change the appearance of your home. This is why when it comes to choosing new windows, you need to do so carefully.

Windows are an expensive investment and they need to last as long as possible. Overall, when choosing new windows, you typically have two options: vinyl or fiberglass. Learning the difference between the two can help you better understand how each would work in your home.


The majority of windows are made from glass, but another major look comes in the frames. Although they look similar from afar, vinyl windows have an obvious join line at their corners. Fiberglass does not, and often mimics the look of windows. Vinyl windows are more basic.

Fiberglass typically gives you more options for color and style because you can paint them. This also means that they may peel and fade. Vinyl windows are typically made of one color, so they will never peel and require less, or no, maintenance.


When you choose vinyl window frames, you will notice that they are made from a flexible material that expands and contracts easily. This means that the frames can be produced exactly to size, they can be installed faster, and are essentially more efficient than a fiberglass window.

Fiberglass is rigid and unable to expand or contract easily. This means it can be more difficult to fit into the window opening, taking more time to install.

For both fiberglass and Vinyl Windows Denver, it is best to have a professional take on the installation. Although some can be installed yourself, it is not recommended.

The Cost

Between vinyl and fiberglass windows, vinyl is usually an inexpensive material. This means that it will also be a lot less to install than fiberglass, being around 30% cheaper.


Fiberglass is more expensive than vinyl, which makes sense as to why it is also up to eight times stronger than vinyl. This also means that as long as it is properly maintained, it can last for a very long time. Good vinyl is often rated for up to 30 years, and fiberglass windows can last 50 years or more.


Fiberglass and vinyl are both made from plastic, but fiberglass frames are reinforced with glass fibers. This adds more strength and can allow them to be a lot thinner as well.

Additionally, vinyl frames may weaken in the sun at 165 degrees. This means that you need to ensure you are placing them in the right areas of your home.

Energy Efficiency

Energy efficiency is important to any homeowner. Both vinyl and fiberglass can insulate well, but fiberglass is known to be a bit better at insulating than vinyl. This makes it more efficient but, still with a higher price tag.
