Reflectix Insulation in Running Springs, CA | North Tustin Insulation
We provide independent Reflectix sales, installation, and repair across Running Springs, CA including the 92382 ZIP.

Why Running Springs Residents Choose Us for Reflectix Service
Running Springs cabins built between the 1940s and 1970s rarely had any real insulation installed, and the retrofits that have been done often used materials that fight the mountain climate instead of working with it. We know Reflectix product lines in detail because we’ve specified them across the San Bernardino Mountains for years: Double Reflective rolls, Perforated Radiant Barrier, the moisture-resistant crawl space facing, and the seam tape that holds the whole assembly together. Allen Decker, our owner, grew up in the Cowan Heights neighborhood of North Tustin, where he learned early that a house without proper insulation is just an expensive box, and he’s been hands-on with mountain retrofits ever since. We’re the contractor that can tell you the difference between an R-3.7 bubble-core roll with an air space and an R-21 assembly, and why that distinction matters in a Running Springs winter. If you’re comparing quotes, remember: if you can’t name the product and the R-value, you don’t have a quote, you have a guess.
We’re an independent Reflectix service provider. We are not manufacturer-affiliated or authorized, and that independence matters because our recommendation is driven by what your specific Running Springs cabin needs, not by a brand mandate. See our full Reflectix sales & service capabilities.
Common Reflectix Insulation Problems We Solve in Running Springs
- Non-perforated foil installed wrong-side down on a roof deck. In Running Springs, a non-perforated radiant barrier stapled tight to the underside of a roof deck traps moisture between the foil and the sheathing. When a hard freeze hits, that trapped moisture turns to ice, thaws, and delaminates the foil facing. We pull it, re-deck with perforated Reflectix, and add the venting the assembly needed in the first place.
- Bubble-core Reflectix compressed into rafter bays with no air space. Reflectix only delivers its stated R-value when there’s a reflective air space. In old Running Springs cabins with shallow rafter bays, well-meaning installers stuff the bubble foil tight against the deck. That collapses the air space and drops the R-value to nearly zero. We see this constantly in vaulted open-beam ceilings.
- Seams left unsealed with tape. An unsealed seam in a radiant barrier is a bypass. Hot summer radiant gain pours through the gap in August, and cold winter drafts leak through the same seam in January. We use Reflectix-brand seam tape so the adhesive and facing match the foil, and we seal every seam we touch.
- Radiant barrier used as a substitute for bulk R-value. This is the big one in Running Springs. A 1960s cabin with no insulation needs R-30 or better in the roof assembly, not a layer of foil stapled over tar paper. Foil alone won’t stop ice dams at the eaves. We’ll tell you that directly, and we’ll recommend combining Reflectix with spray foam or dense-pack cellulose where bulk R-value is required.
- Foil fastened directly against conductive framing without a thermal break. In vaulted open-beam ceilings, foil stapled directly to the rafters creates a winter condensation plane. Warm interior air hits the cold framing, moisture forms on the foil surface, and over time the foil facing degrades. A proper install requires a break between the foil and the conductive wood.
Reflectix Service in Running Springs: What Local Conditions Mean for Your Equipment
Running Springs sits at roughly 6,000 feet in the San Bernardino Mountains, which means roof decks here alternate between hard freezes and hot dry Santa Ana afternoons. A Reflectix radiant barrier installed over a vented roof deck has to be layered with proper eave and ridge ventilation or it traps moisture that turns to ice at the eaves, a balance flatland Inland Empire installs never have to strike. This is the single most important local factor we deal with on Running Springs Reflectix jobs, and it shapes everything from which perforation pattern we spec to how we baffle the rafter bays. Take the cabins up off Highway 18 near Arrowbear, or properties needing Reflectix repair in Crestline: those properties sit at slightly higher elevation and get heavier snow accumulation, so the venting detail matters even more. We’ve opened 1960s vacation homes with vaulted open-beam ceilings and found rafter bays lined with tar paper and pine needles under a single layer of non-perforated Reflectix stapled tight to the deck, no air space, no venting, and heavy ice-dam staining at the eaves. We pulled the foil, cleaned and re-decked with perforated Reflectix over new baffles with a proper air gap, tied in ridge venting, and topped the flat ceiling sections to keep heat from escaping on single-digit nights. The owner reported the ice dams at the eave stopped that winter. That’s the difference between mountain-aware Reflectix work and a flatland crew that doesn’t know what frost does to foil.
Reflectix Models & Products We Service in Running Springs
We work with the full Reflectix lineup: Double Reflective Insulation Roll in the bubble-core configurations (R-3.7 to R-21 depending on application and air space), Reflectix Radiant Barrier Perforated for roof decks and attics, the Double Reflective with moisture-resistant backing for crawl spaces, and Reflectix Insulation Tape and Fastener Kits for seam sealing and attachment. We use authentic Reflectix rolls and Reflectix-brand seam tape, not generic aftermarket bubble foil. The thinner Mylar on aftermarket foil fails at the freeze-thaw cycles Running Springs dishes out every winter. We stock common Reflectix products for fast turnaround on Running Springs jobs, and we’ll order specialty configurations when your project calls for them. This is part of our broader Running Springs service area commitment.
Reflectix Service Pricing in Running Springs
Reflectix radiant barrier installation in Running Springs typically runs $1.75 to $3.25 per square foot for materials and labor, depending on access, roof pitch, and whether you need venting work done alongside the foil. Attic radiant barrier retrofits in older cabins with limited access run higher, often $1,200 to $2,800 for a full attic. Crawl space applications under pier-and-beam foundations generally land between $600 and $1,800. What drives cost here is the mountain factor: narrow winding roads off Highway 18 and 330 make material staging slower, and heavy snow years compress the workable season.

FAQs – Reflectix Insulation in Running Springs
No. A radiant barrier reflects radiant heat; it does not provide enough bulk R-value to stop ice damming at the eaves. Ice dams form when warm air from the living space melts snow on the roof deck, and the water refreezes at the cold eave edge. Fixing ice dams requires a combination of air sealing, bulk insulation, and proper eave and ridge ventilation. Reflectix can be part of that assembly as a radiant and ember layer, but it won’t solve the problem alone. Call (877) 265-5712 and we’ll walk you through what your specific roof actually needs.
Perforated. In a vaulted open-beam ceiling in Running Springs, the roof deck needs to breathe. Non-perforated foil traps moisture against the sheathing, and at 6,000 feet that moisture freezes, thaws, and delaminates the foil. Perforated Reflectix allows vapor to pass through while still reflecting radiant heat, which is the correct spec for a vented roof deck assembly.
It can, but it won’t fix the underlying problem. Reflectix needs an air space to deliver its rated performance, and it’s a radiant barrier, not bulk insulation. In a cabin with no real insulation, the right move is usually to combine Reflectix with dense-pack cellulose or spray foam in the rafter bays to get the R-value up, then layer the foil as a radiant and ember layer. We’ll tell you if foil alone is a waste of money on your cabin.
Because it’s probably installed without an air space, or it’s being asked to do a job it was never designed for. Reflectix bubble foil delivers its R-value through a reflective air space; compress it against the deck or framing and the R-value collapses to near zero. And even properly installed, a radiant barrier is not a bulk insulator. In a Running Springs winter with single-digit nights, you need real R-value in the roof assembly, not just foil.
Yes. Reflectix Double Reflective with moisture-resistant backing is designed for crawl space applications, and it’s a good fit for the pier-and-beam foundations common in Running Springs. The key is installing it with the reflective surface facing the air space and sealing the seams with Reflectix tape. In a mountain crawl space, you also want to consider ground moisture and ventilation so the foil doesn’t trap condensation against the floor framing. Call (877) 265-5712 for a free crawl space assessment.
