Energy-Efficient Windows

Energy-efficient windows prevent heated and cooled air from escaping, decreasing your dependence on artificial heating and cooling systems, which in turn leads to reduced electricity bills. They also create a comfortable living environment and can increase your home’s resale value.

Energy-efficient windows are designed with a number of features that minimize heat loss and increase insulation, including multiple panes separated by gas fills for added insulation and low-E coatings to reflect sun’s harmful rays. This helps cut down your energy costs and reduces your carbon footprint.

Renewal by Andersen

Renewal by Andersen is a nationwide company that specializes in replacement windows for existing homes. Its products are designed to fit in the frame of the old window and replace the sashes, windows stops, and glass insert. The company offers seven standard window styles including double-hung, bay, and bow windows as well as awning windows.

The company’s frames are made from Fibrex, a blend of recycled wood fiber and thermoplastic polymer that is strong and durable. The windows are low-maintenance and easy to clean. They are also Energy Star-certified and help homeowners reduce their energy bills.

The company’s limited warranty is transferable if you sell your home within the warranty period, which is a big plus for homeowners who plan on selling their property in the near future. However, the company’s prices are higher than those of some competitors and its window selection is less broad. This may limit the company’s appeal to potential buyers who have specific needs and preferences.


Vinyl is the second most popular plastic in the world, behind polyethylene. It’s used for products like windows, siding, and fences. It’s a durable material that can stand up to weather changes and withstand heavy use. Plus, it’s recyclable, though most curbside recycling programs don’t accept it.

ENERGY STAR certified window replacements have been shown to save homeowners money on energy costs. They are a great choice for Murray homeowners who want to make their homes more environmentally friendly. If you’re considering a new installation, look for a local provider with a long track record of satisfied customers.

Modern windows are designed with simplicity and minimalism in mind. They offer sleek lines and clear glass, making them an excellent option for newer homes or commercial building renovations. They can be clad with materials like aluminum or fiberglass to add durability and style. You can also choose a contemporary style that uses mixed materials like wood and aluminum.


Window replacement helps reduce drafts and air infiltration that raise energy bills and strain your HVAC system. Investing in high-performing windows also decreases carbon emissions and helps create a healthier living environment.

When choosing window frames, consider materials and cost based on local climate factors, your energy efficiency goals and the style of your home. For example, clad-wood windows are a great option for homeowners looking to achieve a natural design without breaking the bank.

Multi-pane and enhanced sealing technology helps increase thermal insulation and acoustic performance. This feature is especially helpful for homes located near busy streets, allowing homeowners to enjoy a quieter interior space.


Windows account for 25%-30% of a home’s energy use. Upgrading them to high-performing replacement windows will cut energy bills, improve resale value and possibly qualify you for energy saving tax credits.

Compared to single-pane windows, double or triple-pane windows offer better insulation. The additional layer of glass and air or gas between the panes prevents heat loss and minimizes unwanted sunlight. This decreases a building’s cooling needs in the summer and heating costs in the winter, making it more cost-effective to maintain a comfortable temperature throughout the house.

Window frames should be made of an insulating material, such as vinyl. Wood and fiberglass also provide excellent thermal properties. It’s best to avoid metal frames, as they are a conductor of heat and less energy-efficient.

Look for windows with a U-factor and SHGC, as well as a VT, air leakage and condensation resistance rating. These are based on the National Fenestration Rating Council (NFRC) labeling and determine the energy performance of each window.
