Pella® Impervia® features our patented fiberglass composite called Duracast® ― it's the strongest, most durable material available in windows and patio doors.* This material can take most anything, including extreme weather, impacts and sea air.
When it comes to durability, fiberglass is king. And, fiberglass windows are resistant to even the most extreme heat and cold — and even damaging UV rays and seacoast environments. Similar to vinyl, fiberglass windows are easy to care for. They arrive with a long-lasting powder-coat finish that doesn’t need painting and stays looking great for years.
Fiberglass windows closely resemble the look of painted wood — they don’t have a shiny appearance. Available in White, Tan or Brown. White is a great choice for homes with today’s popular white painted woodwork. Or choose Tan or Brown to complement stained wood trim better. With their outstanding heat resistance, fiberglass windows can be manufactured in darker colors, giving you more design flexibility.
Offering the insulating qualities of wood, fiberglass windows are extremely energy-efficient and a great choice for all areas of the country.
Cost-wise, fiberglass is a mid-range choice for homes in all price ranges.
- Homes where the look of painted wood is desired.
- When low-maintenance interiors and exteriors are important.
- Homes that experience extreme heat or cold, or sea air.
