How Johns Manville Products Fail, and How We Fix Them

Johns Manville builds solid insulation products, but nothing lasts forever, especially in Santa Monica’s marine air. Here are the failure modes we see most often during home energy audits, and what we do about them.

• JM Kraft-Faced Batts losing their facing seal. The kraft paper facing acts as a vapor retarder, but in Santa Monica’s humid coastal air, the paper can delaminate or tear, especially in older homes near the pier. When the facing separates, moist air migrates into the insulation and cuts its R-value. We find this constantly in homes built in the 1960s and 70s, and the fix is usually removing and replacing affected batts with fresh Johns Manville or equivalent material.
• JM Attic Protector blown-in fiberglass settling below its rated depth. Blown-in insulation settles over time, and JM Attic Protector is no exception. We regularly measure R-19 product squashed down to an effective R-11 or R-12 in Santa Monica attics, particularly after roof work or decades of gravity. During an audit, we measure depth across the entire attic floor, identify thin spots, and quote a top-up to restore the original R-value, often with the same Johns Manville material.
• JM Corbond III closed-cell spray foam with skipped cavities or thin passes. This one is almost always an installation problem, not a product problem. Corbond III is a quality closed-cell foam, but if a previous crew sprayed it too thin or missed a stud bay entirely, the foam performs far below spec. Our thermal imaging picks up those cold spots instantly. We can cut out and re-spray affected areas or use a compatible closed-cell product to fill the gaps.
• JM ComfortTherm batts with damaged or missing encapsulated facing. ComfortTherm is designed with a plastic encapsulated wrap for cleaner handling and better performance, but that wrap can tear during retrofit work or if rodents get into the attic. Torn facing means exposed fiberglass, which wicks moisture and loses thermal performance. We see this a lot in older Santa Monica bungalows where attic access is tight and someone squeezed insulation into spaces it was never meant for.
• JM Spider fiberglass insulation air leakage around rim joists and top plates. Spider is a spray-in fiberglass system that depends on a tight cavity for full performance. In Santa Monica homes with older framing or seismic retrofits, the rim joist areas and top plates leak air like a screen door. A home energy audit with a blower door test pinpoints those leaks, and we seal them with foam or caulk before any insulation is touched.

Our Johns Manville Home Energy Audit Process

Here is exactly what happens when you call us for a Johns Manville home energy audit in Santa Monica.

1. 1
   You call (424) 396-5828. A live person answers, asks a few questions about your home, your insulation, and what you have noticed, and schedules your audit. No phone tree, no call center.
2. 2
   We arrive and walk the property with you. Our tech introduces himself, shows his ID, and listens to what you have noticed: hot bedrooms, cold floors, high bills, musty smells. Then he gets to work.
3. 3
   Blower door test. We mount a calibrated fan in an exterior door frame and depressurize the house. This measures total air leakage in CFM and shows us exactly where outside air is sneaking in through your Johns Manville insulated envelope.
4. 4
   Thermal imaging inspection. An infrared camera scans walls, ceilings, and attic floors, revealing missing insulation, settled spots, air leaks, and moisture problems that no visual inspection can catch.
5. 5
   Insulation and duct inspection. We get into the attic or crawl space, measure insulation depth, check for compression, moisture, rodent damage, and verify what Johns Manville product you actually have versus what the previous owner said you had.
6. 6
   You get a written report. Photos, measurements, a room-by-room breakdown, and a prioritized fix list with honest pricing. No pressure. You decide what you want done, and the Done Right Promise backs everything we touch.
