If you’re in the market for replacement windows, you’re probably wondering how well those new windows will perform once installed. Since each window size and style will score differently, there’s no single answer to this question. However, there are multiple tools and resources at your disposal to give you an accurate estimation of what you can expect from your new windows. Let’s take a look at those tools and what they can tell you.
An efficient window built for Minneapolis would be a very inefficient window for Houston, which is why it is important to work with a local company like Custom Windows! Everything from the glass configuration, frame materials, to the type of gas between the panes needs to change to accommodate the efficiency needs for different climates. While it is possible to buy windows that will work in most environments, to maximize the efficiency of your new windows and doors, work with our experts in Houston’s climate.
Energy Performance Ratings
You can determine the energy efficiency of a particular window by paying attention to two particular factors:
- U-Factor: This refers to how well a window insulates and keeps heat from escaping outside during winter. While this measurement is more critical for colder climates, Texas Energy Codes still require the window to have a U-Factor of 0.40 or lower. The better the insulating factor of a window, the lower the U-Factor number is and the more efficient the window will be.
- Solar Heat Gain Coefficient (SHGC): This refers to how well a window reflects solar infrared (heat) away, keeping it from getting into your home in the first place. This is obviously an important measurement in Houston, with a more stringent requirement that a window must have a maximum SHGC of 0.25.

The Best Windows for Your Home
It is estimated that homes lose 25 to 30% of the energy through windows and doors, which is one of the reasons energy-efficient windows are an important part of home renovation projects. If you are considering upgrades to your home, improving your efficiency with new windows and doors is an excellent place to start!
