What’s the difference between fiberglass and vinyl windows?
The difference between fiberglass and vinyl windows lies in materials and performance. Vinyl windows are affordable, low-maintenance, and offer durable, weather-resistant frames. Fiberglass windows combine the features of vinyl with the strength of wood, offering enhanced durability and thermal stability. They also utilize advanced window technology for superior energy efficiency and design flexibility.
Can I get a woodgrain finish?
Yes, fiberglass windows are available in woodgrain textures, allowing you to enjoy the aesthetic appeal of real wood windows. The woodgrain finish provides a classic, natural look that complements a variety of architectural styles, while the fiberglass material ensures durability. This finish gives you the best of both worlds—a beautiful appearance with minimal upkeep.
Do fiberglass windows require a lot of maintenance?
No, fiberglass windows are incredibly low maintenance. Unlike wood windows that may require regular painting, staining, or sealing, fiberglass windows are designed to withstand the elements without deteriorating. They resist moisture, rot, and warping, so you don’t have to worry about costly repairs or upkeep. Simply clean them occasionally to keep them looking fresh, and they will continue to perform well for years to come.
Is installation included in the price?
Yes, installation is included in the quoted price. We provide professional installation with AAMA-certified installers, many of whom have over 30 years of experience. Our skilled team understands the specific procedures required for installing each window type, ensuring a seamless installation for every manufacturer.
