Radiant Barrier DFW

Traditional insulation is like a sponge — it soaks up heat and slows it down. Radiant barriers are a bouncer at a Deep Ellum bar: "Sorry heat, you're not on the list."

A radiant barrier is a reflective material installed on the underside of your roof decking. It reflects radiant heat away from your attic. In DFW, where summer attic temps hit 140-150 degrees, that matters a lot.

Radiant barrier works differently than insulation. Insulation slows conductive heat transfer through the ceiling. Radiant barrier reflects radiant heat — the kind that radiates from hot roof decking down into your attic. They work best together: Batman teaming up with Superman.

We install two types. Foil radiant barrier is a reflective sheet stapled to the underside of the roof decking. This is the most effective option, reflecting up to 97% of radiant heat. Spray-on radiant barrier is a ceramic-infused coating applied directly to the decking. Less effective than foil but easier to install in tight spaces. Perforated foil is recommended — it lets moisture pass through and prevents mold.

One thing I'll be straight with you about: radiant barrier alone won't solve your attic problems. It works best in combination with adequate blown-in insulation. We typically recommend R-38 blown-in fiberglass plus a radiant barrier for maximum savings.

We've measured attic temp drops of 25-40 degrees after radiant barrier installation on a 100-degree DFW day. That means your AC runs less, your ductwork stays cooler, and your upstairs bedrooms stay comfortable.

Our promise

Cuts attic temps by 25-40 degrees. Combined with R-38 blown-in for maximum DFW energy savings.

Frequently asked questions

Does radiant barrier really work?

Yes, in hot climates like DFW. We've measured attic temperature drops of 25-40 degrees after installation. It works best combined with adequate attic insulation.

Do I need both insulation and radiant barrier?

For maximum energy savings in DFW, yes. Insulation slows conductive heat transfer. Radiant barrier reflects radiant heat. They address different parts of the equation.

Which radiant barrier is better — foil or spray-on?

Foil is more effective (reflects up to 97%). Spray-on is easier to install in tight spaces but slightly less reflective. We recommend foil for most attics.
