How to Decide Between Fiberglass and Vinyl Windows

If you’re considering new or replacement windows for any area of your home, you have several robust choices in terms of window frame material. Two of the most common, and which are often compared to one another in several areas, are fiberglass and vinyl windows.

At Price’s Guaranteed Doors, we’re your one-stop shop for all things entry doors, garage doors, Pella windows and more to clients around Salt Lake City, St. George, Boise and nearby areas. Our selection of window replacements includes a wide range of energy efficiency windows, from Pella to other top brands, and features both vinyl replacement windows and fiberglass window options. Here are some basics on the construction of both these types of windows, plus a run through several top window priorities that clients typically have – and which of these materials holds the edge in each, helping you make a final decision if you’re unsure of which to choose.

Basic Construction

Before we get into specific qualities of these windows, let’s look at how they’re made. When you hear the term “vinyl” window, what’s actually being referred to is a truncation for polyvinyl chloride (PVC), which is known as a very durable, long-lasting type of plastic. Vinyl windows use these materials for frames and sashes, the two primary components that form the window’s basic structure.

Fiberglass windows, on the other hand, are made from glass fibers being coated with resin material. This is then shaped into long strips or sheets in different shapes and sizes to serve as framing for both fixed panes and operable sections.

So how do these materials compare in terms of top window replacement factors? Let’s dive in for the rest of this blog.

Energy Efficiency

Naturally, window efficiency is a top priority for many homeowners. In this area, fiberglass has a notable edge over vinyl. Fiberglass is an excellent insulator that keeps heat and cold outside of the home, ensuring your interior temperature remains consistent regardless of external conditions.

This is not to say that vinyl windows are inefficient – they’re still an improvement over older styles of windows, for instance. However, their efficiency is more tied to the quality of installation and other factors – fiberglass windows often have better built-in properties in this area.

Durability

In many cases, people are comparing these two materials due to a need for new or replacement windows specifically because their current ones are worn down or inefficient. In these scenarios, durability is a key factor that will impact your decision.

Here, fiberglass once again holds an advantage. While vinyl is usually long-lasting as well, it can sometimes warp or become brittle over time due to prolonged exposure to sunlight and harsh weather conditions. Fiberglass, on the other hand, has excellent resistance to warping or cracking, even in extreme temperatures.

Up-Front Cost

One area where vinyl has the edge? Up-front cost. Vinyl windows are generally more affordable than fiberglass, and often have similar or even better efficiency ratings. If you’re on a tight budget, vinyl may be the way to go.

Maintenance

What about maintenance? Here, the two materials are relatively even. Both require minimal upkeep and are easy to clean with simple soap and water. However, vinyl may require more frequent cleaning due to its tendency to attract dust and dirt.

DIY Installation

For some homeowners, the ability to install their own windows is a major factor. In this area, vinyl windows once again hold an advantage – they are relatively easy for DIY installation compared to fiberglass.

In fact, we don’t typically recommend attempting to install fiberglass windows yourself, as they require precise measurements and a higher level of skill for proper installation.

Decorative and Aesthetic Factors

One area where both types of windows are fairly equal? Aesthetic qualities. Both vinyl and fiberglass can be customized to match your home’s style, with various colors and finishes available. However, some homeowners prefer the look of real wood over vinyl or fiberglass windows, so if this is a priority for you, you may want to consider other materials such as wood windows.

Noise Reduction

Let’s touch on noise reduction abilities. While both materials will reduce noise compared to older, single-pane windows, fiberglass once again holds an edge here due to its superior insulation properties. If reducing outside noise is a major concern for you, we recommend considering fiberglass windows for your replacement project.

Sustainability

Finally, many homeowners are concerned about the environmental impact of their home renovation projects. In this area, both materials have pros and cons. Vinyl windows can be recycled, but they do emit toxic chemicals during production and may not be as environmentally friendly as some other options. Fiberglass, on the other hand, has a lower carbon footprint and is often made from recycled glass fibers.
