Searching for replacement windows in Austin, TX can mean a lot of research on review sites. You can reach out to friends and family for recommendations, too. Infinity Replacement simplifies the process by handling the ordering and installation of your windows for a seamless experience.

Energy efficient replacement windows in Austin help reduce heat transfer from the outside and inside of your home. Energy efficient windows can help limit the amount of solar heat that enters your home. They can also help your home keep cool air inside. The type of window glass you choose plays a role in that. Window glass comes with thin, transparent metallic coatings that can reflect heat back out. Infinity Replacement has five metallic coating options designed for different climates.

Front doors have several material options. You can choose materials like fiberglass, steel, and wood. Each has its advantages and disadvantages. Fiberglass entry doors have strength and energy efficiency. Steel entry doors have durability and don’t require a lot of maintenance. Steel, however, conducts thermal energy more than fiberglass. That means heat passes through it easier than fiberglass. Wood has classic appeal that many homeowners enjoy. Wood doors can need routine maintenance to stay looking good.

The best windows for hot climates in the Southern climate zone will have U-factors of 0.32 or less and Solar Heat Gain Coefficient (SHGC) numbers of 0.23 or less. ENERGY STAR® provides a window climate zone finder tool you can use to find ENERGY STAR-certified window criteria. In general, in the Southern climate zone, look for windows with a lower SHGC number to reduce heat flow.

The best window frame material for hot climates will help prevent heat transfer from hot outdoor temperatures. Infinity's Ultrex fiberglass is 5,000x less conductive than rolled-form aluminum.

Fiberglass doors are considered the best for hot climates because the material has properties to keep heat from passing through it. Infinity's Ultrex fiberglass patio doors’ low thermal conductivity combined with energy efficient glazing options can help save money on your energy bills.1

1Source 2023: D+R International in support of ENERGY STAR. Savings estimates are based on EnergyPlus 9.5 modeling for typical homes in 132 U.S. cities. Ranges are based on the average savings among homes in modeled cities. Actual savings will vary based on local climate conditions, utility rates, and individual home characteristics.

You can prepare for window replacement in your home by clearing the area around the installation area. Any furniture needs moving, and window treatments taken down. It’s also a good idea to clear a path to the installation area. If you have any pets in the home, you’ll want to keep them away from the work area. If you have children, it’s important to prevent them from entering the workspace. You’ll want to disable any security devices before installation and reactivate them after the work is completed.

Have a question? We’re here to help.

With Infinity Replacement – Austin, you’ll get a stress-free experience from consultation to installation. Your project begins with a no-hassle appointment — schedule today to get started!
