Reflectix Insulation in Claremont, CA | Laguna Hills Insulation
We’re independent Reflectix installers serving Claremont, not a manufacturer arm or authorized dealer. The single thing that separates our Reflectix work here is that we treat foil-bubble barrier as a system: airspace, perforation, eave ventilation, and roof type all matter before the product ever goes up. Call (866) 393-6041 for a free estimate on radiant barrier, attic baffle work, or ventilation prep anywhere in the 91711 ZIP code, or for Reflectix service in Upland.
Why Claremont Residents Choose Us for Reflectix Service
Reflectix is one material among eight brand lines we carry, which means we’ll tell you plainly when it’s the right call and when it isn’t. In Claremont’s older homes near the colleges and across the north side, foil-bubble radiant barrier often makes excellent sense above a plaster ceiling. In a tight 1960s attic with no airspace to hang it properly, closed-cell spray foam from Icynene or Demilec usually does more for less fuss. That’s the honest material comparison most single-line contractors won’t give you.
Garrett Lund, our owner, grew up in Laguna Hills and spent years getting attic retrofits right in the older ranch and Craftsman homes that South Orange County and the Pomona Valley share in common. He learned building science at Saddleback College, and he’s been diagnosing how structures hold and lose heat for more than two decades. When he walks a Claremont attic, he’s looking at the whole thermal picture, not just where foil can go. “The right material in the right place does the work. Everything else is just sales pitch.”
We also carry genuine Reflectix roll stock and Reflectix-brand foil tape, so seams and facings are rated for the same attic temperatures. No generics substituted unless a specific width isn’t available anywhere.
Common Reflectix Insulation Problems We Solve in Claremont
- Foil facing delaminating from the bubble core. Under Claremont’s clay-tile and low-slope roofs, attic surfaces cycle well past 140°F every summer. Years of that radiant cycling eventually separate the foil from the polyethylene bubbles, leaving bare plastic that reflects almost nothing. We see this most often in ranch homes built between 1955 and 1975.
- Barrier installed flat with no airspace. This is the most common failure in Claremont’s postwar tract attics. Reflectix draped over ceiling joists or laid across old fiberglass with the foil touching a surface drops to near-zero reflective performance. Radiant barrier needs an air gap on at least one side to function. We re-hang these runs properly or replace them if the bubble core has collapsed.
- Tape seams and staple lines failing on kneewall runs. Santa Ana wind events push dust and hot air through Claremont’s older vented attics. Over time, seams along gable kneewalls peel and staples pull loose, opening radiant gaps that show up as hot upstairs bedrooms in July. We restaple and re-tape with Reflectix foil tape rated for the same heat load.
- Perforated and non-perforated mixed up. In crawl spaces and humid-side wall applications around Claremont’s older homes, the wrong barrier traps moisture against plaster or subfloor. Homeowners read the condensation as a leak and call a plumber. We identify the mix-up, specify the right perforation, and redo the run so vapor can escape where it needs to.
- Foil installed on the wrong side of the roof deck, trapping heat. On Claremont’s hotter summer days, stapling Reflectix directly to the underside of the sheathing can actually hold heat against the roof rather than reflect it back out. We see this shortcut from other crews in Craftsman attics near the Village. The fix is re-hanging with airspace below the rafters and baffles at the eaves.
Reflectix Service in Claremont: What Local Conditions Mean for Your Equipment
Claremont’s older Craftsman and bungalow homes near the colleges are largely balloon-frame structures with original plaster ceilings. That framing style changes how radiant barrier installs correctly. In a balloon-frame attic, the plaster below and open wall cavities below the knee walls create air paths most crews never account for. A radiant barrier has to hang with a real airspace below the rafters and above the plaster ceiling. Stapling foil directly to the underside of the roof deck, the shortcut we’ve seen multiple times in bungalows off College Avenue, actually traps heat against the sheathing on a 95°F July afternoon. The roof deck gets hotter, and that heat radiates down into the upstairs rooms anyway. Proper Claremont work means hanging the barrier under the rafters with eave baffles so airflow moves between the foil and the roof sheathing. That’s the difference between a product that works and one that just looks reflective in an attic photo.
In the 1950s-70s ranch and tract homes across Claremont’s north and east sides, attics are shallow and often carry old fiberglass that’s settled to R-9 or worse. Reflectix over that fiberglass without airspace does nothing. We often dense-pack walls first, then lay or re-hang radiant barrier where it has room to breathe.
Reflectix Models & Products We Service in Claremont
We install and repair the full Reflectix line you’re likely to find in Claremont attics: Double Reflective Insulation Roll in 16 in. and 24 in. widths, Single Reflective Insulation Roll, Perforated Radiant Barrier for humid-side and wall runs, and the Reflective Foil Tape and Radiant Barrier Staples we keep on the truck for seaming and fastening work. We use genuine Reflectix roll stock and brand tape for repairs so the reflective surface and adhesive share the same attic-temperature rating. If a specific width or perforation isn’t obtainable, we’ll say so and use a comparable foil-bubble product rather than pretend it’s identical.

FAQs – Reflectix Insulation in Claremont
In almost every case we diagnose in Claremont, the barrier lost its airspace or the foil facing delaminated from years of 140°F-plus heat cycling under tile and low-slope roofs. Lying flat against insulation or the roof deck collapses reflective performance to near zero. Call us to check whether it’s a re-hang or a replace, not a patch job. (866) 393-6041.
Yes, and it’s one of the better retrofit options for Claremont’s balloon-frame Craftsman attics, but only if the barrier hangs with airspace below the rafters and above the plaster. Stapling directly to the roof deck traps heat. We hang it correctly, baffle the eaves, and leave the plaster untouched.
No. Reflectix is a radiant barrier, not bulk insulation. In a Claremont ranch with settled fiberglass at R-9, a barrier reduces radiant gain in summer but you still need proper thermal insulation for winter heat loss and overnight comfort. We’ll tell you what the attic actually needs before touching the radiant side.
Non-perforated goes on the warm, dry side; perforated goes where moisture needs to pass through. In Claremont crawl spaces and older plaster walls, using non-perforated on the wrong side traps condensation and looks like a leak. We specify the correct product for each cavity, no guessing.
Most Claremont attics run $900 to $2,200 for supply and install, with roof-deck re-hangs and baffle work pushing toward $3,000 on larger homes. Every estimate is free and includes an attic walk. Call (866) 393-6041 and we’ll give you the exact number for your roof.
