Reflectix Insulation in Fresno, CA | Woolsey Insulation Fresno
We’re Woolsey Insulation Fresno, an independent contractor that installs and repairs Reflectix radiant barrier, duct wrap, and reflective insulation across Fresno every working day. You can reach us at (559) 785-2658. The thing that makes our Reflectix work different here is simple: we’ve spent years watching how this specific foil product behaves in Fresno’s 105°F summers and dust-heavy valley air, and we know exactly which installation details fail first. If you need straight answers about whether Reflectix is right for your attic, or you’re also considering our Spray Foam Insulation in Fresno, call us and Glenn Hartley or one of our techs will talk you through it.
Why Fresno Residents Choose Us for Reflectix Service
Plenty of insulation crews in Fresno will staple up foil. Few of them work with Reflectix as a dedicated product line, and fewer still understand what happens to that foil after five or ten summers of valley heat. We do, because Reflectix sales & service has been a core part of our attic work in this city for years. We carry genuine Reflectix material for radiant barrier and duct wrap replacements, and we don’t mix brands on a single retrofit. Off-brand foil can’t match the stated emissivity or tear resistance, and in a Fresno attic, that difference shows up fast.
Glenn Hartley grew up in Los Angeles and got his start in the trades at Los Angeles Trade-Technical College, where he learned building science fundamentals and figured out that insulation was the part of construction most people got wrong. He’s spent well over a decade working in the Central Valley, and his crew has done everything from tight attic retrofits in Tower District bungalows to new construction out near Woodward Park. Glenn will climb into your attic himself before quoting anything. Look before you quote – every attic tells you something the paperwork won’t.
Common Reflectix Insulation Problems We Solve in Fresno
Here’s what we actually find when we open Fresno attics and inspect Reflectix products:
- Sagging or torn radiant barrier on roof decking. Fresno attics routinely hit 140°F to 150°F in summer. Staples pull loose, foil tears along the ridge, and what was once a functioning radiant barrier ends up hanging in dusty strips. We remove the old material, prep the deck, and install fresh Reflectix with proper air gap spacing.
- Duct wrap seams opening up. The foil tape holding Reflectix duct wrap seams together loses adhesion in dry heat. Once a seam opens, conditioned air leaks into a hot attic and your A/C works harder. We re-tape with high-temperature foil tape rated for 200°F continuous, and replace any wrap that’s torn beyond repair.
- Dust-coated reflective surfaces. Fresno’s valley air puts a fine layer of dust on everything, including the shiny side of your radiant barrier. When emissivity climbs from 0.05 up to 0.30, heat reflection drops by over 20%. You can’t just wipe it clean in most attics; replacement is often the honest fix.
- Compressed bubble insulation behind kneewalls. Reflectix bubble insulation only works when it has an air gap. Stuff it behind a kneewall or under batt insulation and it turns into a conductor instead of a reflective barrier. We see this constantly in older Fresno homes where someone tried to add insulation without understanding how foil products function.
- Improper original installation. A lot of Reflectix in Fresno was installed wrong from day one: no air gap, wrong orientation, or staples in the wrong place. We redo it correctly or tell you honestly if a different product makes more sense for your attic.
Reflectix Service in Fresno: What Local Conditions Mean for Your Equipment
Here’s something most insulation pages won’t tell you about Fresno specifically: homes built before 1985 weren’t required to have any radiant barrier or attic ventilation standards. That means the thousands of wood-frame, low-pitch stucco houses across Fresno’s older neighborhoods become solar ovens by 3 p.m. every July afternoon. We see it in the Tower District, along Shaw Avenue corridor, and throughout the Sunnyside area. The attic air temperature climbs past 140°F, the ceiling below it starts radiating heat into living spaces, and your air conditioner runs nonstop during PG&E peak hours when summer weekday rates hit $0.62 per kilowatt-hour. Reflectix foil installed on the underside of the roof deck, with a proper 1-inch air gap, can cut ceiling heat gain by up to 40% in exactly these homes - though some homeowners pair it with Fresno Attic Insulation for even better results. That’s not a manufacturer’s claim; that’s what we measure with infrared thermometers before and after our retrofits.
Our crew was called to a 1968 stucco ranch in the Tower District after the homeowner’s upstairs bedrooms hit 92°F by 5 p.m. every day. In the attic, the original Reflectix radiant barrier had torn along the ridge and was hanging in dusty strips. We removed the old foil, vacuumed the roof deck, and installed new ST16025 Double Reflective Insulation at 2 inches below the decking with a 1-inch air gap, then re-taped every seam with foil tape. The next afternoon, the same bedrooms stayed at 78°F with the A/C cycling normally.
Reflectix Models & Products We Service in Fresno
We install, repair, and replace these Reflectix product lines in Fresno attics and crawl spaces:
- Reflectix Double Reflective Insulation (ST16025). The workhorse for attic radiant barrier applications. We install it on roof decking undersides in older Fresno homes where heat gain through the ceiling is the main problem.
- Reflectix Radiant Barrier (RB4812550). Used for roof deck applications where a single-layer reflective surface is the right call. We stock this for quicker turnaround on Fresno retrofit jobs.
- Reflectix Duct Wrap Insulation (DW12025). For wrapping HVAC ducting that runs through hot attics, a common need in Fresno where ductwork sits in 140°F air all summer.
- Reflectix Bubble Insulation (BP24025). Used selectively for kneewalls, garage doors, and specific cavity applications where an air gap can be maintained.
We carry enough of these products in our Fresno inventory to handle most residential jobs without waiting on a supplier. For larger retrofit projects, we order direct and schedule installation within days, not weeks. Since we’re an independent contractor, we pick the exact Reflectix product that fits your attic, not whatever happens to be on the truck.

FAQs – Reflectix Insulation in Fresno
Yes, it works, but dust is the enemy. Fresno’s valley air coats reflective surfaces with fine particulate that raises emissivity from 0.05 to 0.30, which drops heat reflection by over 20%. Keeping soffit vents clean and ensuring the foil is installed with the reflective side facing downward, where dust settles less readily, helps. But if your existing Reflectix is heavily dust-coated, replacement is usually the better fix than trying to clean it. Call (559) 785-2658 and we’ll inspect it.
Yes, but not directly on top. Reflectix needs an air gap to function, so laying it flat over blown-in fiberglass defeats the purpose. The right approach in a Fresno remodel is either installing it as a roof deck radiant barrier above the fiberglass, or removing the old fiberglass and installing Reflectix with proper air gap spacing. We assess what’s already in your attic before recommending anything.
Properly installed Reflectix can last 10 to 15 years in Fresno’s heat, but we’ve seen it fail in half that time when staples pull loose or dust builds up. The foil itself doesn’t degrade quickly, but the installation details do. Sagging, tearing, and tape failure are what shorten its life. A free attic inspection will tell you how much life your current installation has left. Call (559) 785-2658.
The foil tape seams open up from dry heat exposure long before the duct wrap itself shows visible damage. Once a seam opens in a Fresno attic, conditioned air leaks into a space that’s 140°F in summer, and your cooling bill climbs. You can’t see this from the outside in most cases. We find it with a simple thermal inspection, then re-tape with high-temperature foil tape or replace the wrap entirely.
No, not when installed correctly. The radiant barrier sits inside the attic on the underside of the roof decking, not above it. Roof surface temperatures are affected by shingle color and attic ventilation, not by a reflective surface inside the attic. Fresno’s sun is hard on shingles regardless, but Reflectix doesn’t accelerate that. We recommend checking attic ventilation alongside any radiant barrier retrofit because pre-1985 Fresno homes often lack adequate venting.
