Your insulation slows heat down. It can't turn heat away. Sol-R-Shield™ multilayer reflective foil stops up to 97% of radiant heat at the roofline — before it ever reaches the rooms below.
Most insulation protects against conduction and convection — that's what R-value measures. But Houston's real enemy is radiant heat: the sun cooks your roof, and the roof radiates that heat straight down into the attic. Summer attics here routinely pass 140°F, and traditional fiberglass starts struggling above 110°F — it absorbs and transfers heat instead of stopping it.
That's where emissivity comes in — the measure of radiant heat transfer. Sol-R-Shield™ leads on exactly the number that matters most in a hot climate. Coupled with adequate blow-in insulation, it creates a complete answer to all three kinds of heat transfer.
Heat radiates the same way you feel warmth near a fire without touching it. A Houston roof deck sits in direct sun for hours, then radiates that heat straight down — like a heat lamp aimed at your ceiling. That's why an attic passes 140°F even over a thick, well-installed layer of insulation.
Insulation resists conduction and convection — heat moving through materials or through air. It does nothing for radiant heat, because radiant heat doesn't creep and it doesn't need moving air. It travels in a straight line until it hits a surface. More fiberglass won't stop it. Only a surface built to reflect it will — that's the one job an attic radiant barrier is for.
Placement is everything. We install Sol-R-Shield across the rafters and roofline, with an air gap between the foil and the roof deck — not draped across the attic floor. A reflective surface only works facing open space; buried under floor insulation, foil has nothing to reflect into, and it can trap moisture against the wood. Installed at the roofline, it faces the heat source directly. In attics we've measured, that's the difference between a 140°F summer high and one that settles near 105°F after treatment — same sun, same roof.
A radiant barrier reflects radiant heat. That's it. It isn't a substitute for insulation depth, and foil alone won't fix an attic that's actually short on fill. Most Houston homes we assess need both — the reflective layer for radiant heat, enough blown-in insulation underneath for everything else. We'll tell you when your attic only needs one. We won't sell you the one it doesn't.
Mixing these two up is the most common misunderstanding we hear on a call. They solve different problems:
Depth with no reflective layer still bakes in direct sun. A reflective layer over thin insulation still loses conditioned air overnight. Most Houston attics we measure are short on one, sometimes both — the free assessment tells you which.
Sol-R-Shield™ reflective insulation blocks up to 97% of radiant heat. A Tennessee Valley Authority field study measured a 16–40% reduction in summer attic heat transfer — with the biggest reductions on the hottest days, which is exactly when your AC needs the help. Field tests also show radiant barriers do not increase roof temperatures — a common myth.
About one day, start to finish. We tarp the attic access and the path below so nothing tracks into the house. Foil goes up across the rafters, fitted around ductwork and can lights — can lights need clearance so heat doesn't trap against a fixture that isn't rated for it. We photograph the attic before and after, so you see the difference yourself. Browse real before & after attics from Greater Houston. Full cleanup before we leave.
Homes built before the mid-2000s often have no radiant barrier at all — it wasn't standard in Houston construction until more recently, and a re-roof rarely adds one unless it's requested. Dark shingles absorb more heat than light roofing, which pushes attic temperatures higher. The symptoms are usually obvious: upstairs rooms that run hot no matter the thermostat, an AC that runs nonstop on sunny afternoons but keeps up fine after dark, or an attic that's uncomfortably hot even with the vents working. Those point at radiant heat, not a duct leak. The free assessment measures your attic's actual temperature, so you're working from a number instead of a guess.

None — they're the same thing. "Radiant barrier" is the general term; Sol-R-Shield reflective insulation is the specific foil product we install.
Depends what your attic is missing. A radiant barrier reflects radiant heat; it doesn't add depth. If your attic is also short on fill, blown-in insulation handles the rest. The free assessment measures both, so you know which one your home needs.
No. Field tests, including the independent TVA study, show radiant barriers do not increase roof deck temperatures. We also install with an air gap, which is part of what makes the reflection work.
About one day — foil across the roofline, fitted around ductwork and can lights, full cleanup, and before-and-after photos before we leave.
No. Every written quote is locked for a full 12 months. An assessment in July still stands in December.
