Reflectix Insulation in Upland, CA | North Tustin Insulation
Reflectix insulation service in Upland means something specific to us: matching a radiant barrier to which side of the 210 your house sits on. We install and repair Reflectix double-reflective foil, attic radiant barriers, and foil tape systems across Upland’s 91784, 91785, and 91786 ZIP codes. North Tustin Insulation is an independent Reflectix installer – not authorized, sponsored, or warranted by Reflectix – and we’ll tell you plainly if a radiant barrier is the right spend for your attic or the wrong tool. Call (877) 265-5712 for a straight answer and a free estimate.

Why Upland Residents Choose Us for Reflectix Service
We work with Reflectix because it’s a specific product, not a generic category. But we also know that a roll of double-reflective foil performs differently in a 91784 foothill attic with knee walls than it does in a 91786 tract house with a low-pitch roof. That’s the work. Our crews have handled both sides of the freeway enough to know where foil earns its keep and where it’s just a shiny layer trapping heat. Our owner, Allen Decker, grew up in the Cowan Heights neighborhood of North Tustin and learned the trade through the Building and Construction Technology program at Santiago Canyon College before running residential jobs across the Foothill communities, including Reflectix service in Claremont. He’s the guy who’ll tell you the R-value, the product name, and why it matters for your specific attic. We’re an insulation-only contractor, so Reflectix isn’t a sideline – it’s what we think about all day.
Common Reflectix Insulation Problems We Solve in Upland
- Dust-dulled foil in 91784 foothill attics. Santa Ana wind events push fine grit into under-vented attics north of the 210. Unsealed Reflectix edges and perforations collect that dust, which dulls the low-emissivity surface. The foil still looks shiny from the attic opening, but it’s not reflecting much anymore. We clean, re-seal, or replace depending on how far the degradation has gone.
- Staple and tape failures on under-rafter installs. Upland attics swing hard – 100°F-plus in summer, cool winter nights. Staples that missed the rafter or cheap foil tape lift in those temperature cycles. Panels sag, seams open, and the barrier starts letting heat in instead of reflecting it out. Re-hanging with proper fasteners and genuine Reflectix tape fixes it.
- Reflectix laid flat over compressed batts in 91786 tract attics. This is the most common mistake we find south of the 210. Homeowners or previous contractors lay foil directly on top of old, compressed fiberglass. Reflectix needs an air gap to function as a radiant barrier. Without it, the foil just traps heat against the insulation. We tell people straight when this is the problem.
- Condensation trapped in the roof assembly. Foil-faced Reflectix installed tight against roof decking without ventilation prep can trap moisture in Upland’s seasonal swings. Dust from Santa Ana winds plus that trapped moisture creates a mess inside the roof assembly. Baffles and airflow matter before any radiant barrier goes up.
- Wrong-width rolls on vaulted and knee-wall attics. Foothill homes in 91784 often have vaulted ceilings and knee walls with limited clearance. The wrong roll width or a sloppy cut leaves gaps, and gaps defeat the reflective surface. We measure the actual cavity, not the guess.
Reflectix Service in Upland: What Local Conditions Mean for Your Equipment
Here’s what most Reflectix pages won’t tell you: Upland splits at the 210 freeway, and that split changes how a radiant barrier should be installed. North of the freeway in 91784, foothill attics with knee walls and vaulted ceilings rarely have the clean under-deck air gap a radiant barrier needs. The foil has to be hung differently – often with baffles and ventilation prep along the roofline first – or it simply won’t perform. South of the freeway in 91786, those 1950s-1970s tract homes with low-pitch attics and open bays are close to ideal for foil installs, but they’re usually fighting original R-11 or no wall insulation at all. Same Reflectix roll, two different jobs. The 91785 historic core adds another wrinkle: older homes with knob-and-tube-era wiring need careful retrofit detailing so the foil never contacts old electrical. 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 Upland
We service the full Reflectix lineup common in Upland attics: the Double Reflective Insulation Roll in 16-inch and 24-inch widths, single- and double-sided Reflective Foil Insulation, the R-21 Attic Wall Radiant Barrier, and Reflectix Insulation Tape and Foil Tape. We use genuine Reflectix rolls and Reflectix-branded foil tape so the adhesive and reflective surface perform as rated. We pair them with compatible baffles and ventilation hardware, not generic foil from the bargain aisle. If your existing Reflectix is intact but poorly installed, we re-hang and re-seal it. If the foil is heat-damaged or your attic lacks the required air gap, we’ll say so and recommend replacement or a hybrid with blown-in insulation. For Upland-specific guidance on what we carry, see our Reflectix sales & service page.
Reflectix Service Pricing in Upland
Reflectix work in Upland is priced by the square footage of the attic and the complexity of the install, not by the roll. Here’s what drives cost:
- Radiant barrier install (under-rafter, new): typically $1.50-$3.00 per square foot, depending on attic clearance and whether baffles or ventilation prep are needed first.
- Re-hang and re-seal of existing Reflectix: typically $0.80-$1.50 per square foot when the foil is in good shape and only the fasteners and tape failed.
- Full removal and replacement: typically $2.00-$3.50 per square foot, including disposal of heat-damaged or dust-degraded foil.
- Attic baffles and ventilation prep: typically $6-$12 per baffle installed, varies with roofline access.

FAQs – Reflectix Insulation in Upland
Yes, often. Those low-pitch south Upland attics usually have the open bays and clearance that a foil install needs to work, and the original R-11 or nonexistent wall insulation means the attic is the highest-impact place to start. But if the existing batts are compressed, we’ll want to address that too. Call (877) 265-5712 for an attic assessment – estimates are free.
Dust dulling, sagging seams, or a missing air gap. In Upland and nearby Reflectix repair in Montclair, Santa Ana wind events push grit into under-vented attics, and if the foil edges weren’t sealed or the staples missed the rafter, the reflective surface degrades and panels drop. Re-sealing with genuine Reflectix tape and re-hanging with proper fasteners restores performance.
Yes, but it’s a different install than a flat tract attic. The 91784 foothill homes often lack the clean under-deck gap, so we prep baffles and ventilation along the roofline first, then hang the foil to maintain the air space it needs. Skipping that prep is why so many foil jobs up there fail.
It can, if installed tight against roof decking without ventilation. That’s a real risk in Upland attics that see seasonal swings and Santa Ana dust. Baffles and airflow go in before any foil goes up – we don’t skip that step.
Yes. We use Reflectix-branded foil tape and genuine Reflectix rolls so the adhesive and reflective surface perform as rated, whether we’re working in Upland or providing Rancho Cucamonga Reflectix service. Generic foil tape lifts in local attic heat, and we’re not interested in doing the job twice. Call (877) 265-5712 for a free estimate and a straight answer on what your attic actually needs.
