Energy Efficient Windows Anchorage

Energy efficient windows in Anchorage could be the difference between spending or saving hundreds of dollars a year! Through improved insulation and a draft-free living area, your heating and cooling system won’t have to work so hard to keep your home comfortable all year long.

With advanced window technology, you can prevent the sun from overheating your home during the summer through heat gain. These insulated windows also avoid losing warmth during the winter. This is called heat loss. ENERGY STAR® reports, “Heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use.”

At Renewal by Andersen, we believe that a combination of durable materials and professional window replacement supports optimal performance for windows. This includes high efficiency! Windows contribute to the practical functionality of your home. Find the best energy efficient windows in Anchorage with Renewal by Andersen!

Update or Replace Existing Windows

When it comes to energy efficient home windows, homeowners must determine if they need simple updates or if a complete window replacement is necessary.

Home windows that are not broken or over twenty years old may benefit from affordable upgrades to save energy. You can also periodically check for drafts. These signs usually mean that your seal has broken and needs caulk. If your windows are old or broken, consider window replacement in Anchorage. Typical signs that your windows aren’t performing anymore could be frequent drafts, persistent condensation, or high electric bills during extreme season.

Explore four features to consider for energy saving windows in Anchorage.

Window Frames

If you’re looking for insulated windows, choose Fibrex® material. Andersen’s exclusive Fibrex® material offers the strength and insulating value of wood with the low maintenance features of vinyl. Fibrex® material never requires painting and will not crack, pit, corrode, or rot. The insulating properties of Fibrex® material offers homeowners some of the best energy efficient windows on the market.

Our exclusive Fibrex® material stays strong, even after 20 years of exposure to severe hot and cold temperatures. This durable window frame is designed for cities that experience extreme climate challenges, like Anchorage.

Energy-Efficient Glass

Energy efficient glass options are the key to regulating a comfortable temperature throughout the year. Renewal by Andersen uses only glass that meets our high standards for durability. We provide a variety of glass options, each designed for specific climates.

At Renewal by Andersen, we value upgrading window technology. High-Performance Low-E4® glass is 47% more energy efficient in winter as compared to ordinary dual-pane glass.[4] This may be the best glass for Anchorage, where winters see an average low of 11°F and sees 75 inches of snow each year. This glass is also beneficial during summer months, although Anchorage rarely experiences high temperatures.

Our double-pane windows are also filled with argon gas, working with Fibrex® material to improve insultation. With multiple snowstorms in a year, residents who live outside of city limits need well-insulated windows in the event they’re snowed in.

Operating Types

Choosing the right window style can reinforce high efficiency windows. You may choose double hung windows for your traditional-style home. Or you may replace your current windows with large picture windows, framing your views of the natural beauty all around you.

Renewal by Andersen ensures that your functioning windows, like double hung windows, are tightly sealed at installation. We prioritize a draft-free living space while giving the option to direct fresh air throughout your home as weather allows. For stationary windows, like picture windows, homeowners can enjoy a beautiful view without sacrificing energy efficiency.


There are two main reasons why professional window installation improves your home energy efficiency. First, trained installers will seal your window properly to prevent significant energy loss. Local experts have the benefit of knowing what type of sealant to use with your climate as well as how much to use to fill gaps without excess.

Second, a professional window installer also understands how to avoid misalignment with precise placement. Proper installation protects the windows from weather damage and ensures they function optimally for years to come.

Renewal by Andersen has replaced more than 8.5 million windows. You can count on us to do the job right with a respectful approach and professionalism you’d expect from an industry leader.

Cost Savings

The cost of energy efficient windows is a common concern for homeowners in Anchorage. A study from SmartAsset shows the cost of utilities in Alaska, clearly showing costs over 30% higher than the national average. That means switching to ENERGY STAR® certified windows could save your hundreds of dollars a year!
