Reflectix Insulation in Van Nuys, CA | Airtight Insulation Co
We install and retrofit Reflectix radiant barrier products across Van Nuys as an independent insulation contractor, and the thing that sets our work apart here is knowing exactly where foil earns its keep in a 140°F Valley attic. We also provide Attic Insulation – Van Nuys solutions when R-value matters more than reflectivity. Most Reflectix installations we see in Van Nuys fail because of air-gap mistakes and unsealed penetrations, not because the product is wrong. We stock the real Reflectix lines and we’ll tell you straight if foil alone won’t solve your heat problem. Call (833) 390-7079 for a free attic assessment.
Why Van Nuys Residents Choose Us for Reflectix Service
We carry and install the full Reflectix sales & service range: the Double Reflective Insulation Roll, the foil-faced sheathing products, the R-8 Reflective Foam Core board, and perforated radiant barrier for vented assemblies. Ruben Acosta built Airtight Insulation Co on a simple standard: no gaps, no guesses, just insulation that does exactly what it’s supposed to. His crews spend their days in Valley attics, and we’ve seen enough flat-stapled foil and dust-buried radiant barrier in Van Nuys to know that the install matters more than the brand name on the roll.
We’re not a Reflectix dealer. That’s an important distinction. We install the product because it works well in the right application, and we’re not obligated to push it where another material makes more sense. If your attic needs R-value before it needs reflectivity, that’s what we’ll tell you. Eight brands, one contractor means the job picks the product, not the other way around.
Common Reflectix Insulation Problems We Solve in Van Nuys
- Foil stapled flat with no air gap. Reflectix’s radiant performance depends on facing an air space. In a low-pitch Van Nuys attic from the 1940s or ’50s, DIY foil often gets stapled tight to the rafters or roof deck, which kills most of the reflective benefit. We remove and re-run it with the correct gap from a crawl position along the eave.
- Perforated vs. non-perforated mismatch. Solid foil laid over a vented attic assembly traps moisture at the deck. Van Nuys bungalows with ridge and eave venting need perforated Reflectix so the assembly can breathe. We match the product to your specific venting configuration.
- Dust-covered and heat-degraded foil. Valley attic dust, plus decades of 100°F+ thermal cycling, dulls the reflective surface and drops emissivity. An older radiant barrier that looks installed can perform like bare sheathing. We test and replace where the emissivity is gone.
- Radiant barrier used as a substitute for air sealing. This is the big one in Van Nuys. Homeowners add foil but leave can-light penetrations and top plates open. In a 105°F attic, those bypasses dump more heat into the house than the foil can offset. We seal first, then decide if Reflectix still makes sense.
- Recovering a botched retrofit. We regularly see foil installed over existing fiberglass batts with no air gap on either side, which wastes the product and traps heat against the ceiling. The fix is a careful re-run with proper spacing, often paired with ventilation correction.
Reflectix Service in Van Nuys: What Local Conditions Mean for Your Equipment
Van Nuys sits in the hottest corner of the San Fernando Valley, where summer temperatures routinely run 15 to 20 degrees above coastal LA and attics climb past 130°F on a regular August afternoon. The housing stock makes it worse: most of Van Nuys is post-WWII single-story stucco tract homes with low-pitch vented attics that leave very little clearance at the eave. That geometry changes how Reflectix has to be installed here. In a cold-climate house with a steep roof, you can stand up and staple foil to the rafters with relative ease. In a 1952 bungalow off Van Nuys Boulevard, you’re on your stomach or your knees, running the roll along a 3-in-12 or 4-in-12 pitch, and the roof deck, not the flat ceiling, is where the radiant barrier actually earns its keep. We gap Reflectix from that low deck and tie it into the ridge and eave vents, because on a shallow roof, radiant heat gain through the deck is the dominant load. Get the gap wrong, and you’ve paid for foil that bakes flat and does nothing. This is the single most common mistake we correct in Van Nuys homes.
Reflectix Models & Products We Service in Van Nuys
We stock and install these Reflectix product lines for Van Nuys attics and garage applications:
- Double Reflective Insulation Roll in 16-inch and 24-inch widths. This is the workhorse for rafter and roof-deck application in vented attics, and we keep both widths on hand to match 1950s rafter spacing without field-trimming waste.
- Double Reflective Foil Insulation with optimized reflective surface for applications where emissivity and surface durability matter most.
- Reflective Foam Core Insulation (R-8 foil-faced foam board) for garage doors, knee walls, and specific cavity applications where you need both reflectivity and some conductive resistance.
- Radiant Barrier / Perforated Foil Roll for roof deck and rafter work in the vented attics common across Van Nuys.
We won’t substitute a generic thin foil where the Reflectix air-gap spec and perforation pattern matter. If a specific width or product isn’t in the truck, we get it from our local supplier quickly enough that most Van Nuys jobs and Reflectix service in North Hills still go same-day or next-day.
Reflectix Service Pricing in Van Nuys
Radiant barrier installation in Van Nuys typically runs between $0.95 and $2.75 per square foot depending on the product line, the attic access situation, and how much removal and correction work is needed. A crawl-space attic with limited eave clearance takes longer than a walkable attic, and that labor shows up in the quote. What a free estimate includes: we inspect your attic, check for existing insulation depth, identify bypasses and can-light penetrations, test any existing radiant barrier, and then give you a line-item price for the specific Reflectix product and labor. You’ll know exactly what you’re paying for before we start. For an exact price on your Van Nuys attic, call (833) 390-7079 and we’ll come out and walk the space with you.

FAQs – Reflectix Insulation in Van Nuys
Yes, when it’s installed with a proper air gap on the rafter or roof deck side and the attic is vented. Reflectix works by reflecting radiant heat before it enters the living space, and in a Valley attic with 130°F-plus deck temperatures, that’s the biggest load to stop. But if the attic has no real insulation on the ceiling or if can-light bypasses are open, foil alone won’t fix the problem. Call (833) 390-7079 and we’ll tell you whether your attic is a candidate for Reflectix or needs work first.
In most Van Nuys homes, the foil was either stapled flat against the roof deck with no air gap, installed as non-perforated product in a vented assembly, or the reflective surface is coated in decades of attic dust. All three conditions kill the product’s performance. We can pull a section and test it, then tell you whether the fix is reinstallation, replacement, or air sealing under the foil. Call (833) 390-7079 for an attic inspection.
Perforated, in nearly every Van Nuys attic with ridge and eave vents. Non-perforated foil can trap moisture against the roof deck, and the dry Valley air doesn’t excuse that; you still get condensation on cool winter nights and the vapor needs a path out. Perforated Reflectix allows moisture transmission while maintaining the reflective surface. We’ll confirm your venting setup before we install.
Yes, and in Van Nuys it usually belongs on the deck, not the floor. Low-pitch 1950s tract homes have shallow roofs where the dominant heat gain comes through the deck itself, not the flat ceiling below. Stapling foil to the deck sheathing with an air gap between the foil and the sheathing is the correct application in a vented attic. Laying it on the floor over insulation is mostly a waste, since dust settles on the foil and kills the emissivity.
Probably not. A radiant barrier reduction of 20 to 30 degrees on the attic side helps, but if your ceiling has no meaningful R-value or the can lights and top plates are unsealed, the heat is still getting in through air movement and conduction. Reflectix plus air sealing and attic top-up is the combination that actually changes comfort in Van Nuys. We’ll give you a straight answer about what your house needs. Call (833) 390-7079.
