Why Choose Our Fiberglass Windows?

Engineered with strands of glass fiber woven through heated resin, fiberglass is generally used in products that require a certain toughness, from boats to hockey masks. This means you can expect any fiberglass windows we install to easily withstand daily wear and tear as well as extreme temperatures. That’s not all, of course, because:

  • You can order our fiberglass windows in styles that will complement your home and serve your needs, whether it’s a double-hung for classic appeal, a sliding for easy ventilation, or special shape for architectural interest
  • Our windows are available in numerous frame finishes, including frame white, brown, sky gray, and even dual colors
  • With options such as foam-insulated frames and triple-pane glass, our fiberglass windows can improve thermal comfort and reduce your energy costs

If you would like to learn more about our fiberglass windows, contact Siding Unlimited to schedule a free consultation. Or, to check out their features for yourself, visit our showroom at 665 Larry Court in Waukesha, WI.
