How Can I Add Natural Light with a Window Expansion without Overheating My Home During the Texas Summers?
While expanding windows to bring in more natural light can be a great way to brighten your home, the Texas heat can be a big concern for property owners. To prevent overheating, we recommend installing energy-efficient windows with advanced glazing options and low-E glass that reflects heat while allowing natural light to fill your space. Adding proper shading elements like awnings or UV-blocking window treatments can also make a big difference. No matter your preferences, our team can help you choose the best materials to optimize lighting while maintaining energy efficiency!
