Radiant Barrier

Radiant Barrier in St. George

A radiant barrier reflects heat from the roof back outward before it radiates down into your living space. In hot, sunny summers, that can help lower attic temperatures and cooling costs.

In plain terms

What a radiant barrier does

Radiant heat is heat that travels in waves from a hot surface — like a sun-baked roof — and warms the materials below it. In an attic, that heat can radiate down through the roof deck and into the space above your ceiling.

A radiant barrier is a reflective material, usually foil, installed in the attic to reflect that radiant heat back outward. It works with insulation, not instead of it: insulation slows heat moving through the attic floor, while the radiant barrier reduces the heat load above it.

Rebates & tax credits

Save thousands with available rebates

Radiant barrier may qualify when it is part of a broader insulation or efficiency project — federal 25C and utility rebates can apply when the full project meets current program rules.

Federal 25C tax credit

The Inflation Reduction Act’s 25C credit toward qualifying home insulation and efficiency upgrades.

Utility rebates

Rocky Mountain Power runs an insulation rebate for qualifying work. (Dixie Power rebates cover heat pumps and electrical, not insulation.)

Energy-efficiency programs

Efficiency-program incentives that can stack on top of federal and utility savings.

What you get

What this service includes

Reflective radiant barrier material installed in the attic

Lower radiant heat gain during hot, sunny summers

A system that works alongside your existing insulation

Our 100% satisfaction guarantee on the work performed

Why radiant barrier matters

A hot, sunny climate is exactly where a radiant barrier makes sense. By reflecting roof heat before it loads the attic, it helps the rooms below stay more comfortable and reduces the strain on cooling equipment.

Summer heat
Reflects radiant roof heat before it builds in the attic.
Reflects
A foil surface sends radiant heat back outward.
Comfort
Helps rooms below the attic feel less heat-loaded.

Our process

How we handle radiant barrier

A short, predictable sequence for this specific service — guided by the findings from your home energy-efficiency inspection.

01

Inspect the attic

We look at roof heat exposure, access, existing insulation, and where a radiant barrier will help.

02

Install the barrier

We add the reflective material in the attic so it can reflect radiant heat back outward.

03

Match the system

We make sure the radiant barrier works alongside your insulation and attic ventilation.

Our Promise

Satisfaction is 100% guaranteed

Our 100% satisfaction guarantee covers installation quality, with redo-or-refund provisions. We do not consider a job done until you are satisfied with the work.

Common questions

Radiant Barrier questions, answered

A few of the questions homeowners ask most about this service. The full list lives on our FAQ page.

Does a radiant barrier replace attic insulation?

No — it works with insulation, not instead of it. Insulation slows heat moving through the attic floor, while a radiant barrier reflects roof heat back outward before it loads the attic. In a hot, sunny climate the two together do more than either alone.

Does a radiant barrier help in winter too?

Its biggest effect is in summer, when it reflects radiant heat from a sun-baked roof before that heat radiates down into your living space. In our hot, sunny climate, that summer cooling benefit is the main reason a radiant barrier makes sense.

How does a radiant barrier lower cooling costs?

Radiant heat travels in waves from a hot surface like a roof deck and warms whatever is below it. A reflective barrier sends that heat back outward, so less of it builds up in the attic — which means less heat loading the rooms below and less strain on your cooling equipment.
