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.

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.

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.
