Energy Efficient Windows in Green Bay, WI

In response to rising energy costs, homeowners are turning to energy efficient windows in Green Bay to reduce electricity bills and enhance home comfort. Green Bay experiences a moderate climate influenced by its proximity to Lake Michigan, with cold winters and occasional lake-effect snow. These local climate conditions underscore the importance of well-insulated windows to maintain indoor comfort and energy efficiency.

According to the Department of Energy (DOE), inefficient windows can account for up to 20% of wasted energy in homes due to drafts and leaks. Installing energy efficient windows in Green Bay not only improves insulation but also tightly seals the window frames, reducing energy consumption and protecting HVAC systems.

Update or Replace Existing Windows

When evaluating your windows, consider their age, condition, and efficiency to determine whether updates or replacements are necessary to enhance energy efficiency and comfort.

If your windows are under twenty years old and still perform well, you may benefit from slight enhancements such as adding window coverings or films to improve insulation during extreme temperatures. These additions can help regulate indoor temperatures and reduce heating and cooling costs.

For older windows or those showing signs of poor performance, such as air or moisture leaks, replacement may be the most effective solution. If you feel drafts or notice condensation inside the windowpanes, it’s time to consider replacing your windows to improve energy efficiency and indoor comfort.

Replacing outdated single-pane windows with double- or triple-pane windows can significantly enhance energy savings by providing better insulation and reducing heat transfer. Choosing energy efficient glass further improves thermal performance, helping to maintain consistent indoor temperatures throughout the year.

Window Frames

When it comes to enhancing insulation, Fibrex® material stands out as an excellent choice for energy efficient windows in Green Bay. This exclusive composite material from Andersen combines reclaimed wood fibers and vinyl, offering exceptional durability and insulation properties. Fibrex® material is known for its strength, lasting twice as long as standard vinyl windows while requiring minimal maintenance.

Energy-Efficient Glass

Energy efficient glass plays a crucial role in maintaining comfort and reducing energy costs throughout the year in Green Bay’s climate. High-Performance™ Low-E4® glass, a premium option from Andersen, provides superior thermal insulation by keeping warmth inside during winter and blocking heat from entering during summer. This window technology is also designed to protect your home from harmful UV rays, helping to preserve furniture and interior décor.

Operating Types

The type of window you choose can significantly impact energy efficiency and comfort levels in your Green Bay home. Consider the following options based on their operational characteristics:

  • Awning and Casement Windows: These windows feature crank-style handles that tightly seal when closed, preventing drafts and enhancing energy efficiency. They are ideal for areas where a tight seal is crucial, such as in windy conditions common around Green Bay.
  • Picture and Specialty Windows: These windows are fixed and do not open, providing a permanent seal that eliminates drafts and leaks. They are perfect for capturing expansive views and maximizing natural light without compromising insulation.
  • Double Hung and Sliding Windows: These windows are designed for easy operation and are professionally installed to ensure a tight fit between the Fibrex® frame and the window opening. They offer flexibility in ventilation and are suitable for various room layouts in Green Bay homes.
