Fiberglass window installation in Wisconsin

For top-notch durability and a lifetime of energy savings, contact our Wisconsin window contractors for fiberglass window installation. 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.

Types and Styles of Windows:

Awning window installation

Awning windows

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

casement window installation

Casement windows

Casement windows can be used alone or in a series to create a bow window. These windows usually feature a hinge on one side and can often be opened outward or inward.

bow window installation

Bow windows

Create more space and let more natural light in with bow windows. These windows are usually made up of multiple casement windows that stick out from the exterior of your home.

sliding window installation

Sliding windows

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

egress window replacements

Egress windows

Egress windows are emergency exit windows commonly installed in basements. Instead of style, these windows are defined by dimensions that meet building code regulations.

specialty window installation

Specialty windows

Custom and specialty window shapes are available to suit the needs of your home's design.

picture window installation

Most double hung windows provide multiple ventilation options - lower the window from the top or raise up from the bottom.

Working with Infinity Exteriors has been great so far. Our salesman Tom was very attentive and worked around our schedule without complaint. We felt we got honest answers and were never pushed. We are very much looking forward to having them do our windows and siding project.
