Andersen Windows FAQ

Andersen windows are designed with energy efficiency in mind. Depending on the series, they offer a range of features to enhance thermal performance, including low-E4 glass coating that reflects heat, multiple pane options with insulating air spaces, exclusive Fibrex composite framing material that insulates better than traditional materials, and weatherstripping to reduce drafts. 

Many Andersen windows are ENERGY STAR certified, meeting strict EPA guidelines. The company has been named ENERGY STAR Partner of the Year for several consecutive years, highlighting its commitment to energy efficiency.

Andersen crafts their windows from different materials optimized for beauty, durability, and performance:

  • Wood: The traditional option with natural beauty. Protected by cladding or fiberglass on the exterior.
  • Fibrex composite: Andersen's exclusive wood fiber and thermoplastic polymer composite. Twice as strong as vinyl.
  • Fiberglass: Strong, low-maintenance frames resistant to decay, fungal growth, and insects.
    Aluminum: For a sleek, modern look. Extremely durable and low-maintenance.
  • Vinyl: Budget-friendly, low-maintenance option that doesn't need painting.
