Radiant Barrier Installation in Utah Attics

Reduce summer radiant gain on hot roof decks. Installed after air sealing priorities, paired with adequate attic R-value.

Utah summers turn vented attics into solar ovens. Radiant barriers address radiant heat transfer from the underside of the roof deck toward ducts, platform floors, and anything else living in the attic volume. They are not magic — they complement insulation and air sealing, not replace them.

Where barriers help most

South- and west-facing planes, dark shingles, and attics that host flex duct runs see the clearest comfort wins. If your ducts live in the attic, lowering radiant load on them can improve delivered air temperature even when the thermostat setpoint stays the same.

Installation philosophy

We install after fixing obvious air leaks at the ceiling plane so you are not radiating heat into a house that is still bleeding conditioned air upward. Barrier products must maintain an air gap facing the radiant surface; we follow manufacturer facing and fastening details so performance matches lab ratings.

Not a substitute for R-value

A barrier will not fix R-19-era attics in January. Winter performance still comes from depth and coverage. We quote barriers as an optional summer comfort layer once the attic floor is honest.

Rebates

Some program years treat radiant barriers as standalone measures; others bundle them under comprehensive attic upgrades. We map the current tariff rather than guessing.

If your upstairs runs hot by 3 p.m. every July, ask us whether your roof geometry fits a barrier — we’ll show thermal images and prioritize sealing first.
