Fiberglass vs. Wood Windows

Thinking about buying new fiberglass windows or wood windows for your Maryland home, but not sure which is the better choice for you? The experts at Quality Window & Door are here to help!

Fiberglass and wood windows are both excellent choices for residential and commercial windows, but there are some differences that may make one a better choice over the other—depending on your situation.

Read on below to learn more about the major differences between fiberglass and wood windows, or contact us today to request a free consultation in the DC, MD, or VA area!


Wood windows tend to be more expensive than fiberglass windows. Since wood windows are highly sought after, their relative scarcity and beautiful aesthetics can make them more expensive. That said, they can also increase the value of your home for future re-sale value. Fiberglass windows are still high end, and may be more expensive than other window materials aside from wood (including aluminum and vinyl).

Strength and Durability

Fiberglass windows are stronger and more durable than most windows, including all-wood windows. Extreme temperatures have almost no impact on fiberglass, so they are less prone to expansion and contraction. This leads to less warping and cracking—which leads to a longer lifespan and better energy efficiency.

That said, wood is one of the oldest building materials and has stood the test of time—so will your windows. Professionally manufactured and installed wood windows still have great durability and strength and will last in your home for years to come. However, warping, rotting, and expansion/contraction of the material is a concern due to extreme changes in temperature or moisture levels.


Fiberglass windows are very easy to maintain. Unlike wood windows, they don’t need to be sanded, painted, or stained to maintain a like-new appearance. A simple cleaning with soap and water will keep fiberglass windows looking new for years.

As said above, wood windows require frequent maintenance to maintain that beautiful, just-installed aesthetic. As the wood is exposed to the elements, they will need to be maintained through scraping, sanding, painting, and staining. With proper maintenance, they can still have an extensive lifespan.

Energy Efficiency

Both wood and fiberglass windows are very energy efficient, making them environmentally-friendly choices for your home. If you want to have the most eco-friendly windows available on the market, however, fiberglass is the choice. Fiberglass is the more energy efficient choice due to its ability to resist expanding and warping—common concerns for wood windows as explained above.
