Is your upstairs always hot and your AC bill too high? A radiant barrier blocks the sun’s heat before it reaches your rooms. We install radiant barriers in homes across San Antonio and the Hill Country. Every job starts with a free inspection and an honest estimate.
A radiant barrier is a thin, reflective material, usually aluminum foil, installed in your attic. It faces an open air space and reflects radiant heat instead of soaking it up. In simple terms, it works like the shade that keeps you cool on a hot day.
The sun heats your roof, and that heat radiates down into your attic. A normal attic traps it, and your rooms get hot. A radiant barrier reflects most of that heat back out before it reaches your insulation and ceilings. Your attic stays cooler, and your AC works less.
There are a few ways to add a radiant barrier to your home:
The most common type. We staple reflective foil to the attic rafters, facing an air gap.
Used in new builds, where the roof decking already has a reflective layer.
A reflective coating sprayed onto the underside of the roof.
We help you pick the right type for your attic and budget.
Our summers are brutal, and a radiant barrier helps a lot:
Less heat in the attic means less work for your AC.
Second floors and bonus rooms stay more comfortable.
A cooler attic protects stored items and your roof decking.
Your system runs less and lasts longer.
It also helps hold heat in during the cooler months.
Your home may be a good fit for a radiant barrier if:
A free attic check tells you for sure.
These two work together, not against each other:
Attic insulation slows heat moving through your ceiling.
A radiant barrier reflects radiant heat before it builds up.
For the best results in Texas, use both. We check your attic and tell you what will help most.
In a hot climate like San Antonio, a radiant barrier can cut cooling costs noticeably by keeping your attic cooler. The exact savings depend on your home, your attic, and your insulation. On top of lower bills, a cooler attic means your AC runs less, which can help it last longer. We will tell you honestly what to expect for your home.
A radiant barrier works even better with a reflective roof. If you are planning a new roof, ask us about metal roofing and cool-roof colors, or a full roof replacement designed with heat in mind.
A radiant barrier works best with good attic ventilation. The barrier reflects heat, and proper vents let the trapped hot air escape. Together they keep your attic much cooler. During your free inspection, we check your current ventilation and tell you if a few vents would make your radiant barrier work even better.
Every attic is different, so the price changes with the job. The main things that affect your radiant barrier cost in San Antonio:
Bigger attics need more material.
Tight or low attics take more time.
Foil sheets and spray-on products cost differently.
We give you a free, written estimate first, so you know the full price before we start.
