Radiant Barrier Installation for Cooler, More Efficient Homes in Central Texas

In the hot Central Texas climate, heat buildup in the attic is one of the biggest causes of high energy bills and uncomfortable indoor temperatures. Homes in New Braunfels, San Antonio, Canyon Lake, and across Comal County can experience attic temperatures well above 140 degrees during the summer. That extreme heat transfers downward into your living space, forcing your air conditioning system to work overtime. At Lone Star Luminaires, we install radiant barriers that block this heat at its source—helping homeowners stay cooler while using less energy.

A radiant barrier is a reflective insulation material installed in the attic that reflects heat instead of absorbing it. Unlike traditional insulation that slows heat transfer, radiant barriers stop heat before it ever enters your home. By reflecting radiant heat back toward the roof, these systems dramatically reduce how much heat is absorbed by your attic and passed into your living areas.

Why Radiant Barriers Are Ideal for Central Texas

Central Texas receives intense sunlight for much of the year, making radiant heat one of the biggest contributors to indoor temperature increases. Even well-insulated homes can struggle to stay cool when the roof and attic absorb constant solar radiation. Radiant barriers are specifically designed to combat this type of heat.



For homes in Comal County and surrounding Hill Country communities, radiant barriers can reduce attic temperatures by up to 30 degrees or more. That means less heat radiates into your home, resulting in improved comfort and significantly lower cooling costs during peak summer months.

Expert Installation for Maximum Performance

At Lone Star Luminaires, proper installation is key to getting the full benefit of a radiant barrier system. Our process begins with a detailed attic inspection to evaluate airflow, insulation levels, and roof structure. This allows us to design a solution that works in harmony with your existing ventilation and insulation.

We install the radiant barrier along the underside of the roof decking or across attic rafters, creating a reflective shield that blocks radiant heat. The material is carefully secured to ensure it remains effective for decades without sagging or tearing. We also ensure that ventilation pathways remain unobstructed so your attic continues to breathe properly.Because radiant barriers require no electricity and no mechanical parts, they are a low-maintenance, long-lasting energy efficiency upgrade.

Reduce Cooling Costs and HVAC Wear

One of the biggest advantages of radiant barrier installation is how much it reduces the workload on your air conditioning system. When your attic stays cooler, less heat enters your home, and your AC doesn’t have to run as often or as long.

This can lead to noticeable reductions in monthly electricity bills, especially during the hottest months of the year. Over time, reduced strain on your HVAC system also means fewer repairs and a longer equipment lifespan.

Protect Your Home from Heat Damage

Extreme attic heat doesn’t just affect comfort—it can also damage your home. High temperatures can cause roofing materials to deteriorate faster, insulation to lose effectiveness, and wood framing to dry out and crack. By keeping attic temperatures lower, radiant barriers help protect the structural integrity of your home.

They also reduce the chance of moisture buildup that can lead to mold and mildew, creating a healthier environment in your attic and throughout your house.
