Why Fiberglass Windows Last a Long Time

Sourced from Pella®, one of the nation’s most respected window manufacturers, these windows are prized for their combination of durability, looks, and reliable performance. But toughness is a big reason for their popularity. Engineered with strands of glass fiber woven through heated resin, fiberglass is typically used in products that require a certain hardness—boats and hockey masks, for example. Our fiberglass windows make for great investment because they can withstand daily wear and tear as well as extreme temperatures without any warping, cracking, or other structural distortions. With Siding Unlimited as your window company, you can:

  • Order our fiberglass windows in styles that will complement your home and serve your needs, whether it’s a traditional double-hung for classic appeal, a slider for easy ventilation, or a special shape for architectural pizazz
  • Choose from numerous finishes for your window frames, including white, brown, sky gray, and even dual colors
  • Select options such as foam-insulated frames and triple-pane glass for improved home energy efficiency that can reduce your energy costs

Contact Siding Unlimited for more information about our fiberglass windows. We have financing available for qualified New Berlin residents and back our window replacement service with a five-year workmanship warranty that’s in addition to any manufacturer warranties.
