Reflectix Insulation in Whittier, CA | North Tustin Insulation
We provide independent Reflectix service across Whittier, from South Whittier Reflectix service to radiant barrier roof decking and foil-faced duct wrap. What makes our work here different is simple: most Whittier homes were built before 1960, and their shallow attics, knob-and-tube wiring, and compacted original insulation mean a Reflectix install is never a roll-and-staple job. It takes air gaps, vent corrections, and foil that’s actually oriented the right way. Call (877) 265-5712 for a free estimate, or keep reading to understand what your attic needs.

We carry and install the full Reflectix lineup: double reflective insulation rolls, single-bubble foil, perforated radiant barrier for roof decks, and foil-faced HVAC duct wrap. North Tustin Insulation is an independent contractor, not a Reflectix authorized dealer, so our advice is based on what your attic actually needs, not what a brand program pushes. For broader Reflectix sales & service, we handle everything from material selection to full attic retrofits across the Whittier area.
Why Whittier Residents Choose Us for Reflectix Service
Reflectix foil works when it has an air gap, a clean reflective face, and a vented attic to reject heat into. In Whittier’s older homes, those three conditions are routinely missing. We figure out which one is failing before we touch a roll. Allen Decker, our owner, learned insulation the hands-on way through the Building and Construction Technology program at Santiago Canyon College and spent years on residential and light commercial jobs across the Foothill communities, including Reflectix in West Whittier-Los Nietos, before starting North Tustin Insulation. He grew up in Cowan Heights, where summer afternoons made it obvious early that a poorly insulated house is just an expensive oven.
We are an insulation-only contractor. Eight brands, three installation methods, and every technician focused on one trade. That matters when you call about a Reflectix issue in Whittier because we don’t also do roofs, HVAC, or general remodeling. We do one thing: figure out why your attic runs hot and fix it with the right material. For anyone in the broader Whittier service area, that means a straight answer about whether your existing foil is worth saving.
Common Reflectix Insulation Problems We Solve in Whittier
Here’s what we see most often when a Whittier homeowner calls about Reflectix foil that isn’t performing:
- Mis-faced foil. The reflective surface is pointed at the drywall or buried against sheathing instead of facing an air space. That kills the radiant performance entirely. In Whittier attics where foil was stapled by a previous owner or a handyman, this is the #1 issue we correct.
- No air gap against the roof deck. Radiant barrier stapled flat to the underside of the deck with no gap and sealed-off vents. That traps afternoon attic heat instead of reflecting it. On a 100-degree Whittier summer day, it makes the attic worse, not better.
- Crushed bubble foil under blown-in insulation. Homeowners top up attic insulation and the weight compresses the bubble core, dropping the foil to near-zero effective R-value. We see this constantly in Whittier attics that were insulated in stages over decades.
- Failing tape seams and edge staples. Years of inland heat cycling in a 100°F-plus attic breaks down foil tape and pulls staples loose. The foil flutters, tears at penetrations, and stops forming a continuous barrier.
- Bubble foil stuffed into wall cavities as if it were batt insulation. Reflectix is a radiant barrier, not a cavity fill. When it’s wadded into 2×4 stud bays in Whittier’s older homes, it does almost nothing for conductive heat loss.
Reflectix Service in Whittier: What Local Conditions Mean for Your Equipment
Here’s what’s different about Whittier specifically. The pre-1950 Uptown and Historic Whittier bungalows were framed with shallow, irregular 2×4 joist bays and knob-and-tube wiring sharing the same attic space. A Reflectix job here is rarely a clean roll-out. You have live wiring running through the joist bays, shallow cavities that can’t hold standard batt sizes, and decades of dust and debris packed into the corners. We usually have to build air gaps and work the foil around live wiring before any attic top-up goes in. That’s not true in a newer tract neighborhood, a condo complex, or homes needing East La Mirada Reflectix service. It’s true on Painter Avenue, Greenleaf, and the streets off Philadelphia where the houses date to the 1920s and 1930s. The inland summer heat that bakes Whittier from May through October means the attic is the first stop on nearly every energy audit, and the old knob-and-tube wiring means the foil work has to be done carefully, not quickly.
On a 1940s Spanish-revival cottage off Painter Avenue in Uptown Whittier, the homeowner called because the back bedrooms hit the high 90s by 2 p.m. even with the AC running. We found old bubble foil pressed flat against the roof deck with sealed-off vents. Our crew pulled the crushed foil, re-hung Reflectix radiant barrier with a proper air gap, and reopened the soffit-to-ridge ventilation. Then we blew in attic insulation around the existing knob-and-tube runs. The rear rooms dropped noticeably on the next heat wave and the AC stopped short-cycling.
If you can’t name the product and the R-value, you don’t have a quote, you have a guess.
Reflectix Models & Products We Service in Whittier
We work with the full Reflectix lineup commonly found in Whittier homes. That includes the Reflectix Double Reflective Insulation Roll (bubble-core foil rated R-3.7 to R-4.5 depending on application), the Reflectix Reflective Foil Insulation single-bubble and double-bubble rolls sold at big-box stores, Reflectix Radiant Barrier Roof Decking with perforations for attic ventilation, and Reflectix foil-faced duct wrap for HVAC runs through hot attic spaces.
When existing foil is being installed as a radiant barrier, we use genuine Reflectix rolls and Reflectix-approved foil tape. For staples, baffles, and sealants, we match the aftermarket component to the assembly rather than the brand. If the existing foil is crushed, mis-faced, or trapped against the deck with no air gap, the honest repair usually means re-hanging it with a proper gap or replacing it. Layering more foil over a bad install only hides the problem.

FAQs – Reflectix Insulation in Whittier
Yes, but it has to be worked around the live wiring, not stapled over it. In Whittier’s older Uptown and Historic district homes, we keep the foil clear of knob-and-tube runs, build the air gap carefully, and blow insulation in around the wiring rather than over it. This is standard practice on pre-1950 homes here. If you’re unsure what’s in your attic, call (877) 265-5712 and we’ll take a look before recommending anything.
Only when it’s installed with a reflective face pointing at an air gap and the attic is ventilated. Whittier’s inland heat pushes attic temperatures to 130°F and higher by July, and a properly hung radiant barrier rejects a meaningful share of that radiant heat before it reaches the insulation below. Installed flat against the deck with sealed vents, it does nothing. We correct bad installs or install it right the first time.
Usually no. Blown-in insulation compresses the bubble core, which drops the foil to near-zero effective R-value and leaves you paying for insulation that sits on top of a crushed product. We pull or correct the old foil first, then blow in the top-up. It’s more work, but it’s the only way the assembly actually performs. Call (877) 265-5712 for a free attic assessment and we’ll tell you what your existing foil is worth.
They’re two halves of the same system. The radiant barrier rejects heat at the roof deck, and ventilation carries away the heat that still gets through. In Whittier bungalows with sealed soffit vents and no ridge vent, a radiant barrier alone can’t do its job because the attic has nowhere to exhaust. We check venting first, then hang the foil with an air gap. It’s the only sequence that works in these older homes.
Under the roof deck, stapled to the rafters with a minimum air gap between the foil and the deck. That’s the application where Reflectix performs as a radiant barrier. On the attic floor, it gets buried or crushed and stops working. We’ve corrected enough Whittier attics where foil was laid on the floor like a blanket to know it’s a waste of material.
