Fiberglass Vs. Vinyl: Which Material Better For Your Windows?

Window choice is an important decision when it comes to home improvement. You want to find the best window for your home that meets your needs and fits your budget. There are different materials for windows on the market, but one of the most popular choices is fiberglass and vinyl windows. So, which is better for your home? Let’s find out in this blog post!

1. Energy Efficiency

Fiberglass and vinyl windows have different insulating properties. In general, fiberglass is more energy-efficient than vinyl windows.

Fiberglass windows may be the better option for a window installation if you live in an area with extreme weather conditions. They’re less likely to warp/crack in hot or cold temperatures than vinyl windows. Fiberglass also holds up better against strong winds and hailstorms.

2. Appearance

Fiberglass windows come in multitudes of alluring colors & styles. You can also stain the surface or paint it over to match your home’s trim.

Vinyl windows are available in a limited number of colors. And because they’re made from plastic, they can’t be painted or stained. If you want the color of your choice on your vinyl windows, you’ll need to replace them entirely.

3. Durability

Fiberglass windows last for 30+ years with proper care and maintenance. Vinyl windows have a shorter lifespan and may only last 10-15 years before they need to be replaced. If durability is important to you, fiberglass windows are the better option.

4. Maintenance

Fiberglass windows require very little maintenance and can be cleaned with soap and water. You may need to sand the surface for smoothness if it becomes scratched or chipped. Vinyl windows also require very little maintenance. But because they’re made from plastic, they can become warped or discolored over time from exposure to sunlight. If your area receives hot summers, your vinyl windows may not last as long as fiberglass windows.

5. Cost

Fiberglass windows are more expensive than vinyl windows, but they’re also more energy-efficient and durable. If you’re looking for the most cost-effective option, vinyl windows are the way to go for a window installation. But fiberglass windows are the better choice if you want windows that will last longer and save you money on your energy bills.

6. Installation

Fiberglass windows can be more difficult to install than vinyl windows because they’re heavier. That means you’ll need more help installing them, which will take longer. If you’re doing the installation yourself, vinyl windows are probably a better option. But hiring someone to do the installation won’t make much difference in which type of window you choose.


Choosing the right type of window can be a difficult decision. There are many factors to consider when making your choice. The type of window, the material, the installation, and the maintenance all play a role in your decision.
