Living in Texas means dealing with intense summer heat, glaring sun, and rising energy bills. The extreme temperatures don’t just affect comfort, they also damage your roof, overwork your HVAC system, and inflate utility costs. Luckily, modern reflective coating technologies offer real solutions. These coatings bounce solar heat away from your home or building, keeping interiors cooler and reducing energy usage. In this article, you’ll discover five of the most effective reflective coating solutions to beat the Texas heat. We’ll break down how each one works, where it performs best, and how it can benefit you, not just your property.
Why Reflective Coatings Matter in Texas
