CertainTeed Radiant Barrier Installation Nationwide

CertainTeed Radiant Barrier Installation: The Burbank Owner’s Guide

CertainTeed radiant barrier installation in Burbank typically runs $2,800-$4,200 for a standard 1,200-2,000 sq ft attic, and we stock the full CertainTeed line for same-day starts. Most Burbank homeowners figure out something’s wrong when their second-floor bedrooms won’t cool below 78°F even after sunset, or when their summer electric bill jumps 30-40% year-over-year. We’re Topside Attic Insulation Burbank, independently operated and not affiliated with CertainTeed, and we install their MemBrain, SmartBatt, and standard foil radiant barrier systems across the Burbank market.

Which CertainTeed Models This Applies To

CertainTeed’s radiant barrier portfolio breaks into three lines we work with regularly. The CertainTeed MemBrain is a smart vapor retarder with a reflective aluminum face, rated at 0.1 perm when dry and 10 perm when wet - it goes on the warm-in-winter side of the assembly, which in Burbank means the attic-side of the ceiling drywall in most retrofits. The CertainTeed SmartBatt is a kraft-faced fiberglass batt with a reflective overlay, manufactured in R-13, R-19, R-30, and R-38 thicknesses; the R-30 and R-38 are what we see in Burbank’s 1960s-1980s ranch homes with 2×10 rafter bays. The standard CertainTeed foil radiant barrier is a perforated, double-sided aluminum sheet, typically installed as a draped product over rafters or as a stapled deck application.

Here’s the compatibility gotcha: MemBrain and SmartBatt are not interchangeable. MemBrain is a vapor retarder first, radiant barrier second; it belongs on the conditioned side. SmartBatt is insulation with a radiant barrier component; it belongs in the cavity. We’ve found Burbank homeowners who had a handyman flip them, trapping moisture against the drywall in winter and nullifying the reflective value in summer. The model number prints on the kraft facing every 24 inches - look for “CT-SB-R30” format for SmartBatt, or the MemBrain roll tag with lot number and perm rating.

OEM CertainTeed vs. aftermarket: for the foil barrier, we stock both. The OEM perforated foil runs heavier at 0.5 mil aluminum on each side; aftermarket equivalents often drop to 0.3 mil and delaminate faster in Burbank’s 110°F+ attic peaks. For MemBrain and SmartBatt, we run OEM only - the adhesive pattern and facing alignment are proprietary, and we’ve seen aftermarket batts slump in 2×10 bays after two summers. We also stock Reflectix as an alternative line for homeowners who want a different price point or have compatibility issues with older CertainTeed systems.

Signs Your CertainTeed Radiant Barrier Installation Is Failing

• Hot ceiling patches at high noon. You’re feeling radiant heat punching through where the barrier has torn, slipped, or was never continuous. In Burbank’s climate, a 1% gap in coverage can drop system effectiveness by 15-20% because radiant heat travels line-of-sight.
• AC runs continuously from 2 PM to 8 PM. The barrier’s emissivity value has degraded - usually from dust accumulation on the foil face or oxidation if the attic venting is poor. Burbank’s Santa Ana wind events blow fine dust through ridge vents, and after 5-7 years it cakes up.
• Visible sagging or fallen sections. The staples pulled out or the tape failed. This is common in Burbank’s Magnolia Park neighborhood homes with skip-sheathing roof decks; the 1×6 boards don’t give the staple enough purchase, and summer thermal cycling works them loose.
• Water stains on the ceiling below the barrier. You have a vapor retarder installed wrong-side-out, or a non-perforated foil trapping moisture. CertainTeed MemBrain is designed to adapt its perm rating; standard foil is not. In Burbank’s occasional winter rains, this shows up as a February ceiling spot.
• Energy bill spikes with no rate change. The barrier was never paired with adequate insulation depth. R-value and radiant barrier work together; a foil layer over R-11 in a Burbank attic is cosmetic. We see this in flip-house purchases where the previous owner did the minimum.

Replacement Cost & What’s Included

Most CertainTeed radiant barrier replacements in Burbank fall between $2,800 and $4,200 installed. At the low end, that’s a straightforward foil swap in a clean attic with good access hatch and clear decking. At the high end, you’re looking at MemBrain or SmartBatt in a cramped attic with HVAC ducting to work around, plus removal of the failed existing product.

What drives the range: attic square footage, product line selected, and whether we find unsealed top plates or can-light penetrations that need addressing first. Under our Haven Standard, we don’t blow or install over unsealed air leaks - the R-value is what the label says. The performance is what the blower-door test says. We care about the second number.

Every job includes: written price before work starts, removal and responsible disposal of old barrier, installation per CertainTeed specs, and a Documented Photo Record. Where we’re also air-sealing, you’ll get before-and-after blower-door numbers. The 365-Day Done Right Promise applies to all work.

DIY or Call Us?

Here’s what you can safely check yourself: verify the product label if it’s visible, measure your attic square footage, and photograph any fallen sections from the hatch - don’t climb around. Burbank’s 1960s ranches often have 4/12 pitches with truss bottom chords that aren’t walkable.

Where DIY goes wrong: working near energized romex in a hot attic, misidentifying MemBrain vs. standard foil and installing it on the wrong side, and compressing SmartBatt into bays too shallow for the labeled R-value. The perforated vs. non-perforated decision matters for moisture management, and getting it wrong voids any meaningful warranty and can damage your ceiling. We carry full CertainTeed inventory on our trucks, and Wes Okafor sequences every job with air sealing first, then barrier or insulation second.
