Fiberglass Windows: The Energy-Efficient Choice

Fiberglass is fast-becoming the most commonly used material in home construction. Doors made of fiberglass are now more popular than wood and the same goes for windows. If you’re planning to replace your existing windows soon, fiberglass is a material to look for.


At Timberland Exteriors, we offer expert window installation service. In this post, we share the benefits of installing fiberglass windows.

Wood-Look Windows

Fiberglass has the uncanny ability to replicate the appearance of natural wood, with solid grain finishes that are near-indistinguishable from the real thing. Whether you’re looking for a true earthy tone or the ashy aesthetic of ghost gum, fiberglass can replicate it!

Durable and Low-Maintenance

Similar to how fiber cement siding has overtaken wood, fiberglass is now the preferred material for windows due to its innate durability and low-maintenance properties. It’s virtually immune to rotting and warping, and only requires cleaning to keep it looking good.

The Best Insulating Material

Fiberglass also surpasses wood in its insulating capabilities, with the material expanding and contracting along with the glass window. This makes the windows very energy-efficient, limiting thermal transfer and increasing the comfort levels in your home.

The Strength of Fiberglass

Fiberglass is also one of the stronger composite materials, able to hold large pieces of glass. This makes the material the best choice for windows with large glass areas, such as bay, bow, and ceiling-to-floor picture windows.


At Timberland Exteriors, we’ll make sure your new fiberglass windows are properly installed so you can get the most out of your new investment. We also offer new roof installation.

When it comes to roof maintenance, most homeowners focus on shingles, flashing, or gutters. But two of the most critical—yet often overlooked—components are the soffit and fascia. These structural elements play a silent but vital role in maintaining your roof’s integrity, ventilation, and overall curb appeal.
