Keeping Your Home Comfortable in San Antonio’s Heat
Living in San Antonio means dealing with some of the hottest temperatures in Texas, and that can really take a toll on your home’s comfort and your energy bills. If you’ve ever felt like your air conditioner is working overtime or noticed your cooling costs creeping higher every summer, you’re not alone. The good news is that there are smart insulation options designed specifically for homes in this region that can help keep things cooler inside while saving you money.
Local Expertise You Can Trust
At Green Energy of San Antonio, we’ve been helping families in San Antonio and nearby communities improve their homes’ energy efficiency for over 20 years. We focus on quality, made-in-the-USA products, and offer solutions tailored to the unique challenges of South Texas homes. Let’s explore the insulation options that can make a real difference in your home’s comfort and energy use.
Spray Foam Insulation: A Powerful All-Around Solution
One of the most effective insulation materials for combating the intense heat of San Antonio summers is spray foam insulation. This type of insulation expands upon application, filling gaps and cracks that traditional materials might miss. By creating an airtight seal, spray foam not only prevents cool air from escaping but also keeps hot air from infiltrating your home.Â
This dual action can lead to a significant reduction in energy consumption, making your air conditioning unit work less and ultimately lowering your utility bills. Additionally, spray foam can help reduce noise pollution, providing a quieter and more serene living environment.
​​Reflective Insulation: Beating the Heat from Above
Another excellent option is reflective insulation, which is particularly beneficial in areas with high temperatures and direct sunlight. This type of insulation reflects radiant heat away from your home, keeping your living spaces cooler even on the hottest days.Â
When combined with traditional insulation in your attic or roof, reflective insulation can create a highly efficient thermal barrier. This is especially important in San Antonio, where the sun’s rays can heat up roofs and attics to extreme temperatures. By investing in reflective insulation, homeowners can enjoy a more comfortable indoor climate while also extending the lifespan of their HVAC systems.

Radiant Barrier Installation: Reflecting Heat Away
One of the most effective ways to reduce heat gain in your home is by installing a radiant barrier in your attic. Unlike traditional insulation, which absorbs heat, radiant barriers reflect radiant heat away from your living spaces. This means your attic stays significantly cooler, which helps reduce the overall temperature inside your home.
In San Antonio’s blazing summers, radiant barriers can lower attic temperatures by as much as 70 degrees Fahrenheit. This reduces strain on your air conditioning system and can save you up to 35% on your annual cooling costs. Installation is quick and clean, and it won’t interfere with your Wi-Fi or cell phone signals. Plus, the products we use come with a lifetime warranty so that you can count on long-term benefits.
R-30 Attic Insulation: Creating a Thermal Blanket
In addition to radiant barriers, we install R-30 blown-in fiberglass insulation in attics. This type of insulation acts like a thermal blanket, filling in gaps and creating a barrier that slows heat transfer. While radiant barriers reflect heat, fiberglass insulation absorbs it, so combining the two can be especially effective at managing your home’s temperature.
Our attic insulation services come with project minimums. You’ll need at least 1,000 square feet of coverage, but the investment pays off by improving comfort and reducing energy bills. Unlike some other insulation types, our fiberglass options are safe, environmentally friendly, and long-lasting. Proper installation is key to achieving the right density and thickness, ensuring the best possible performance.
With R-30 insulation, your home will stay cooler in the summer and warmer in the winter, making your living spaces more comfortable year-round. It’s a solid choice if you’re looking to upgrade your attic insulation with a trusted, professional team.
Energy-Efficient Window Replacement: More Than Just Insulation
While attic insulation plays a huge role in energy efficiency, windows are another critical factor. Old, drafty windows can let heat in during the summer and cold air out during the winter, driving up your utility bills. That’s why we offer energy-efficient window replacement services, focusing on retrofit installations for existing homes.
Our vinyl replacement windows come in styles like casement, slider, picture, and double-hung, and are designed to reduce outside noise while improving insulation. These windows require very little maintenance and resist warping, cracking, or fading, so they look great and perform well for years. By upgrading your windows, you can save up to 35% on your energy bills while boosting your home’s curb appeal and value.
Keep in mind, we do require a minimum of five windows per replacement project, ensuring you get the full benefit of a comprehensive upgrade. If you’re tired of noisy streets or uncomfortable drafts, switching to energy-efficient windows is a smart move.
