Wood Windows vs. Fiberglass Windows

Are you considering replacing your windows but unsure if wood or fiberglass windows are the better option? The experts at APCO are here to help you decide!

While aesthetic features like window style and color or wood grain play a role in choosing new windows, a frame’s material directly affects a window’s insulating properties and energy efficiency. High-quality windows also have better weatherstripping to keep air from filtering in or out.

Here’s a look at the differences between wood and fiberglass windows and what you should consider before making your choice.


Wood windows are the most expensive replacement option, but they also don’t rust and can last a lifetime — as long as you maintain them.

Fiberglass windows are less costly than wood models, but as they’re also considered high-end, they typically carry a higher price tag than vinyl models.

APCO’s window pricing includes, among other factors:

  • Custom sizing for the perfect fit
  • ENERGY STAR® qualified products
  • Insulated high-performance glass (low-E and argon)
  • Sleek cam-action locks
  • APCO pro installation
  • APCO absolute quality assurance inspection

Strength & Durability

Built to last, fiberglass windows are lighter and stiffer than wood windows and are unaffected by extreme temperature fluctuations.

The strength and durability of wood windows depend greatly on the quality of wood used and whether they’re treated to prevent moisture damage and mold and mildew stains.


Wood windows require regular maintenance to keep them looking and performing their best. You’ll probably need to apply stain and paint touchups, and weather barrier coatings are often needed to protect the wood from rotting or warping. Termites love wood windows, so it’s doubly critical to keep up with maintenance.

Fiberglass windows require far less maintenance than wood windows. Basic soap and water usually does the trick and doesn’t damage the material.

Energy Efficiency

Fiberglass windows have durable UV-blocking coatings and offer similar energy-efficiency ratings as other window choices.

Because wood is a natural insulator, wooden windows are also high in energy efficiency. They prevent air leaks and keep your home refreshingly cool in the summer and comfortably warm in the winter.


Wood windows provide a more natural look. They can be stained to match your home’s exterior or interior decor, or you can paint them to give a dash of color.

Fiberglass windows come in an attractive range of colors to match or complement your home.

Wood vs. Fiberglass Windows: The Choice Is Yours

When choosing a replacement window material, it can help to make a list of the features that matter most to you, keeping in mind the level of maintenance you’ll need to do.
