Top-Tier Fiberglass Windows for Residents of Brookfield, WI

In your search for well-made replacement windows for your Brookfield home, you probably came across a fair number of websites touting the advantages of fiberglass frames. It wouldn’t surprise us. Here at Siding Unlimited, we have been installing fiberglass replacement windows for several years, so we know firsthand just how effective they are at protecting Wisconsin homes from the weather. Made from strands of glass fiber woven through heated resin, fiberglass is known for its toughness. It holds up well in extreme temperatures and withstands daily wear and tear without a problem. Hence, fiberglass is used in boats, bridges, hockey masks, and several other applications that require high-level durability.

Appearance Matters

While utility should always be a concern when choosing replacement windows, any house-proud homeowner would also make style and design a priority. To that end, Siding Unlimited installs gorgeous fiberglass windows from Pella®, one of the nation’s most respected window manufacturers. These windows:

  • Are available in a variety of styles, from double-hung and casement to awning and bay, making them suitable for Wisconsin homes of virtually any architectural design
  • Feature a durable powder-coat finish that lends the elegant look of painted wood
  • Can be ordered in the frame finish of your choice—for instance, brown, white, morning sky gray, or even dual colors

Excellent Thermal Performance

New windows should also improve your home’s thermal comfort, and our fiberglass windows do that exceptionally well. With options such as foam-insulated frames and triple-pane glass, they can help to reduce your energy costs no matter the season.
