Vinyl vs. Fiberglass Windows: Which is Better?

Vinyl vs Fiberglass Windows - Which is Better

Homeowners don’t buy new windows very often. So when it comes time to select replacement windows for homes, most Kansas City homeowners do some research to learn about their options.

We want to help you with your decision by offering our two cents on the vinyl vs. fiberglass debate.

It’s important to note that both vinyl replacement windows and fiberglass windows are great options for Midwest homeowners. There are pros and cons to each type, which we will discuss below. However, one thing is not up for debate – the importance of having a highly-trained crew install your replacement windows. (More on that later.)

Pros and Cons of Vinyl Replacement Windows

Vinyl window frames are made of polyvinyl chloride (PVC) coated with ultraviolet light (UV) stabilizers to keep sunlight from breaking down the window material.

Vinyl windows are easy to care for as they do not require painting. In addition, they do not break down from excess moisture – as wooden windows do.

Vinyl windows tend to be energy efficient as the vinyl frames can be filled with insulation. (You might want to learn about energy efficiency ratings as you continue to research the right replacement windows for your situation.)

Finally, vinyl replacement windows are affordable. By some estimates, vinyl windows may be up to 30% cheaper than fiberglass windows.

Pros and Cons of Fiberglass Windows

Fiberglass window frames are “dimensionally stable,” meaning they can maintain their original shapes and dimensions when subjected to temperature and humidity changes. This trait is particularly important when buying windows for a home in the Midwest.

Fiberglass windows are extremely durable. In fact, your fiberglass windows may last up to 50 years compared with the average 30-year lifespan of vinyl windows.

Besides being durable, fiberglass windows have air cavities that can be filled with insulation. This means they are energy efficient – perhaps even more than vinyl windows.

Fiberglass windows generally have thinner frames than vinyl windows, which means more glass is exposed. They also come in more color options.

The drawback to purchasing fiberglass windows is the price. Fiberglass windows tend to be more expensive than vinyl windows. However, they may be more of a draw to homebuyers because they are more expensive.

Professional Installation Is Important

Regardless if you buy durable, less-expensive vinyl windows or long-lasting pricier fiberglass windows, it’s essential to have them professionally installed by someone particular about the process. Integrity Roofing, Siding, and Windows is one such window company that offers expert installation.
