Products & Materials

  • Fibrex® is a proprietary composite material developed by Andersen specifically for windows and doors. Made from reclaimed wood fiber and thermoplastic polymer, it combines the strength and stability of wood with the low-maintenance benefits of vinyl. Fibrex resists rotting, cracking, peeling, flaking, and warping under normal conditions and never needs painting or staining. Learn more about exclusive Fibrex material.

  • Fibrex® is 2 times stronger and more rigid than traditional vinyl, allowing for slimmer frames and more glass area. It also expands and contracts less with temperature changes, helping window frames maintain their shape and fit over time. Unlike wood, Fibrex does not require scraping, painting, or staining and is designed to resist rot and decay.

  • Yes. Fibrex® has a low thermal expansion rate, which helps it remain stable through significant temperature changes. That makes it particularly well suited for New England conditions, where windows are exposed to freezing temperatures, summer heat, moisture, and seasonal changes.

  • Renewal by Andersen offers a variety of energy-efficient glass options designed for different climates, home orientations, and performance needs. Options include Low-E glass packages that can help reduce heat transfer, improve comfort, and protect interiors from UV exposure. Learn more about Energy Efficiency.

Features such as Fibrex® material, advanced glass packages, and weather-resistant seals help reduce heat loss during winter and help keep unwanted heat out during warmer months.

  • Triple-pane windows can provide additional insulation and improved energy performance, particularly in colder climates like Vermont, New Hampshire, and Northeast New York. The right choice depends on your home's location, existing windows, and energy goals. During a FREE In-Home Consultation, a design consultant can help determine whether double-pane or triple-pane glass is the best fit for your home.

  • Replacement windows reduce drafts, minimize cold spots near windows, and improve temperature consistency throughout your home.

The result is a more comfortable living environment in every season and potentially lower energy usage over time.

  • Absolutely. Even the most energy-efficient window can underperform if it is not installed correctly. Proper installation helps ensure a tight seal, minimizes air leakage, and supports long-term performance and energy efficiency.
