Fiberglass windows are known for their elegant appearance, strength & low maintenance. They’re a common alternative to wood-clad windows since they offer the same look without the high-end price point. Fiberglass is stiffer, lighter, and more resistant to water & temperature changes than wood. While fiberglass typically costs about 25% more than vinyl windows, they offer extreme durability and a longer lifespan. We can install fiberglass casement windows, sliding windows, awning windows, hopper windows, picture windows and more.

Benefits of fiberglass windows

Fiberglass windows offer several benefits over other window materials, such as vinyl, wood or aluminum. Here are some of the main advantages of fiberglass windows:

Wisconsin fiberglass window repairs

Fiberglass windows used to be rarely manufactured and were only available in one color (white). Now they’re distributed nationwide and come in a range of interior/exterior colors. The frames are as easy to paint as wood if you’re looking for a change, and replacing your fiberglass windows isn’t always necessary. If you need a repair on your existing fiberglass windows, contact Infinity Exteriors.

Awning windows

Awning windows swing outward to allow for proper ventilation. These windows are commonly used in basements and bathrooms.

Slider, or glider, windows are opened and closed simply as the glass seamlessly moves across a track.
