Reflectix Insulation in Van Nuys, CA | Porch Light Insulation
We provide independent Reflectix service in Sherman Oaks and across Van Nuys, and the thing that sets our work apart here is simple: we know how these radiant barriers actually behave when a Valley attic hits 150°F. We’re not affiliated with or authorized by Reflectix, but we work with their Double Reflective rolls and foil tape in Van Nuys attics every week. If you’re dealing with peeling foil, sagging batts, or an attic that turns your hallway into a sauna by 4pm, call (877) 521-4987 for a straight answer.
Why Van Nuys Residents Choose Us for Reflectix Service
Most insulation contractors in the Valley treat radiant barrier as an add-on. We don’t. Porch Light Insulation is an insulation-only shop, and Reflectix products are one of the eight manufacturer lines we install. That means when Gil Tanner walks into your Van Nuys attic, he’s looking at the whole envelope, not just the shiny roll stapled to your rafters. Gil grew up in the Cahuenga Pass and spent years working attics in Universal City and the surrounding neighborhoods, so he’s seen what 140°F roof decks do to foil facing, seam tape, and kraft-faced batts. Our crew installs, removes, and rebuilds Reflectix systems with the same rigor whether it’s a 1920s bungalow near Van Nuys Blvd, a home needing Reflectix repair in Encino, or a 1970s tract house off Sepulveda.
We carry genuine Reflectix rolls and Reflectix-brand foil tape for replacements, because the facing and adhesive are the entire point of a radiant barrier system. When a comparable barrier makes more sense for your roof geometry, we’ll say so. We match the material to your home, not to our inventory. Call (877) 521-4987 and we’ll give you a read on what’s actually happening up there.
Common Reflectix Insulation Problems We Solve in Van Nuys
These are the failures we see most often in Van Nuys attics, tied directly to how this part of the Valley bakes in summer:
- Foil delamination on low-slope rear additions. Van Nuys ranches built in the 1950s and 1960s often have flat or low-slope roofs over rear additions with almost no attic air gap. Reflectix stapled directly against hot sheathing with no ventilation gap will bubble and peel within a few seasons. We see this constantly in the 91405 and 91406 grid.
- Rodent-torn Mylar facing in older attics. The pre-war and 1950s housing stock along the 91401/91405 corridor has attics that rats and squirrels treat as a highway. Scuffed or torn foil kills the low-emissivity surface, leaving bare bubble core that reflects almost nothing. We remove and replace, not patch.
- Untaped or wrong-tape seams on DIY retrofits. Homeowners grab a Reflectix roll from a Valley big-box store, staple it up, and skip the seams. Hot attic air bypasses the barrier and radiant performance drops toward zero. We find this on a lot of partial DIY jobs where someone did two weekends of work and gave up.
- Barrier installed over the wrong side of existing kraft-faced batts. No ventilation correction, no air gap, no plan. Heat and moisture get trapped, and the old batts sag underneath. This is especially common in stucco-over-wood-frame Van Nuys homes where exterior retrofits aren’t practical, so every attic mistake compounds.
- Collapsed original insulation under old Reflectix. Many Van Nuys homes still have the original 1950s rock wool or bare joists. Water heater flues, roof leaks, and decades of 150°F attic heat turn that old material into a thin, dirty mat. Adding Reflectix on top without removing the dead layer just hides the problem.
Reflectix Service in Van Nuys: What Local Conditions Mean for Your Equipment
Here’s the thing about Van Nuys that matters more than most people realize: the single highest-impact efficiency work in this city is attic radiant barrier and R-38+ blown-in insulation, because summer attic temperatures routinely sit between 140 and 160°F. Coastal LA homes don’t see that heat load. Van Nuys does, every single day from June through September. A Reflectix Double Reflective roll that works fine in a vented hip-roof attic in West LA will fail over a flat rear addition in Van Nuys unless it’s installed as a proper roof-deck assembly with baffled ventilation. The same roll, the same staple gun, the same homeowner, the same weekend. Different result entirely. Off Van Nuys Blvd and throughout the 91405 grid, we routinely find the original 1950s rock wool crushed to nothing and the previous owner’s Reflectix stapled flat against the sheathing, foil already delaminating and seams untaped. If your attic feels like a different climate than your living room, that’s not a thermostat problem, that’s a building envelope problem, and it’s fixable.
Our Reflectix sales & service work in Van Nuys starts with a roof-deck assessment. We check what the deck geometry actually allows, because a low-slope addition with almost no air gap needs baffles and ventilation correction before any barrier goes back up. On a 1950s stucco ranch off Van Nuys Blvd, our crew found the previous owner’s Reflectix stapled directly against the sheathing over a rear addition, seams never taped, foil peeling in sheets. The original kraft-faced batts were sagging below. We pulled the damaged barrier and collapsed batts, added baffles to open the deck-to-barrier air gap, air-sealed the top plates, reinstalled fresh Reflectix with foil tape on every seam, and topped up the flat ceiling with blown-in. That’s the difference between a radiant barrier that lasts and one that fails by your second summer.
Reflectix Models & Products We Service in Van Nuys
We install and repair the full Reflectix lineup you’ll find across the Valley: Double Reflective Insulation Roll with bubble core and foil both faces, Single Reflective Roll for less demanding applications, Reflective Foil Tape for seam and edge sealing, and the R-21 stapled-up rolls sold at big-box stores. We keep genuine Reflectix rolls and tape on hand for fast Van Nuys turnaround, and we use the manufacturer’s product where it’s going back in because off-brand tape adhesive fails in a 150°F attic within a year. When a comparable barrier fits the deck geometry better, we’ll tell you that too. Insulation is all we do, which means it’s all we’ve mastered. For any Reflectix project in the Van Nuys service area, we’ll size the job correctly before a single staple goes in.
Reflectix Service Pricing in Van Nuys
Radiant barrier work in Van Nuys runs roughly $1.50 to $3.00 per square foot for a straightforward stapled-up install over an existing attic, while full removal of damaged barrier and collapsed insulation plus rebuild with baffles and air-sealing typically lands between $3.50 and $6.50 per square foot. Attic insulation removal alone runs $0.80 to $2.00 per square foot depending on depth and condition. What drives the cost is deck geometry. A vented hip-roof attic is fast; a low-slope rear addition requiring baffle installation and ventilation work is not. Every free estimate includes a roof-deck assessment, an honest read on whether Reflectix is the right product for your specific attic, and a line-item quote. Call (877) 521-4987 to schedule yours, no obligation.

FAQs – Reflectix Insulation in Van Nuys
Does a Reflectix radiant barrier actually help in a Van Nuys attic that hits 150°F? Yes, but only with a proper air gap and sealed seams. Reflectix works on low-emissivity physics: the foil face reflects radiant heat back toward the roof deck, but it needs at least a small air space between the foil and the sheathing to function. Installed correctly with baffled ventilation, a radiant barrier can reduce attic temperatures by 15 to 25°F. Installed flat against the sheathing with open seams, it does almost nothing. We’ll tell you which situation you have. Call (877) 521-4987 for an attic assessment.
My 1950s Van Nuys ranch has bare joists and old rock wool, can I just add Reflectix over it? No, not without removing the dead layer first. The original rock wool in most 1950s Van Nuys attics has collapsed to a fraction of its original R-value, and in many cases it’s contaminated with rodent droppings and decades of dust. Adding Reflectix on top just traps that mess. We remove the old material, air-seal the top plates, install baffles where the deck geometry requires it, then put the barrier and new blown-in insulation in properly. It costs more up front, but it’s the only way the radiant barrier actually works.
Why is the shiny foil on my attic Reflectix peeling and bubbling? Delamination happens when the foil facing overheats against hot roof sheathing with no air gap. Van Nuys roof decks hit 140 to 160°F in summer, and a staple-up install with the foil pressed flat against that heat will fail within a few summers. The fix is removal, proper baffling to create the air gap, and reinstallation with a quality barrier. Patching delaminated foil rarely works, because the emissivity you paid for is already gone. Call (877) 521-4987 and we’ll confirm what’s happening in your attic.
Should I use Reflectix in my crawl space too, or only the attic? It depends on your crawl space condition and whether you’re dealing with floor heat loss or radon and moisture. In Van Nuys, the attic is almost always the higher priority because heat gain is the dominant problem. But a Reflectix barrier can make sense in a dry, vented crawl space under certain conditions. We’ll look at both spaces during your estimate and give you a straight answer on where the money does the most good.
How do I know the seams on a new Reflectix install are done right? Every seam should be sealed with a foil tape rated for high attic temperatures, not duct tape or painter’s tape. The tape should overlap evenly on both edges and lie flat with no bubbles or lifted corners. If you can see daylight through any seam or the tape is peeling within a year, the install was wrong. We use Reflectix-brand foil tape on every Reflectix install and inspect every seam before we leave. Call (877) 521-4987 for a free estimate that includes a full attic walkthrough.
