How Demilec Products Fail - and How We Fix Them

Demilec makes solid foam. But in Palmdale’s climate, even good products develop predictable problems. Here’s what we see, and what we do about it.

• Heatlok HFO shrinkage at the roofline. Demilec’s Heatlok HFO closed-cell line is a workhorse for roof decks, but in Palmdale attics we regularly see shrinkage where installers sprayed too thin in the first pass or where the substrate got too hot during application. The foam pulls back from the rafters, leaving hairline gaps that leak conditioned air. Our fix: we cut out the affected sections, re-prep the surface, and respray to full depth so the air barrier is actually continuous.
• Sealection 500 open-cell density problems. The Sealection 500 line is open-cell, and its whole job is slowing air movement, not stopping vapor. When it’s installed at the wrong density, you get a spongy mess that doesn’t insulate anywhere near spec. We’ve pulled samples from Palmdale walls where the foam never fully cured because the applicator rushed the job in high heat. We re-spray those sections correctly, and we test density before we call it done.
• Off-ratio foam from aging equipment. Demilec two-component systems require precise A-side and B-side mixing. When a contractor runs old or poorly maintained spray rigs, the ratio drifts, and the foam never reaches its rated R-value. In Palmdale we’ve seen this in garage ceilings and rim joists where the foam looks fine from the outside but crumbles when you poke it. We redo the job with calibrated equipment and verify the rise and cure on every pass.
• Moisture trapping in closed-cell over old framing. Heatlok HFO and other Demilec closed-cell foams act as a vapor barrier. In older Palmdale homes with existing moisture in the framing, spraying closed-cell over damp wood seals that water in. We see this in crawl space rim joists and older wall cavities. Our technicians check framing moisture content before we spray, and we won’t install closed-cell where it’s going to cause rot down the line.
• UV degradation on exposed garage foam. Demilec foam left exposed in Palmdale garages breaks down fast. The sun’s UV turns the surface chalky and yellow within a season. We see homeowners try to leave it bare because they like the look. We recommend and apply an ignition barrier or thermal barrier coating, which protects the foam and keeps it performing for the life of the home.

Our Demilec Spray Foam Insulation Process

Here’s how a typical Demilec job goes when you call Warmline Insulation Co. in Palmdale.

1. 1
   Call and diagnosis. You call (661) 613-2043, a live person answers, and we schedule a walkthrough. We assess your attic, walls, rim joists, or whichever area needs foam, and we check existing Demilec foam with a moisture meter and visual inspection.
2. 2
   Straight assessment. Neil Ashford and our crew will tell you exactly what needs replacing, what’s salvageable, and what doesn’t need work. No padded tickets. If the existing Demilec foam is performing, we say so.
3. 3
   Parts and material decision. For repair work, we use genuine Demilec materials whenever the application calls for them, which keeps your project consistent with the manufacturer’s specs. For some sealing and touch-up work, we use quality aftermarket products that match or exceed the original performance. We’ll explain the trade-off and let you decide.
4. 4
   Prep and protection. We cover floors, seal off the work area, and make sure ventilation is right. Spray foam generates heat as it cures, so we control the environment, especially in Palmdale summers when attics are already hot.
5. 5
   Application and verification. We spray to the correct depth and density, then check the foam’s rise, cure, and adhesion before we pack up. If the number’s off, we fix it on the spot.
6. 6
   Cleanup and the 90-Day Done Right Promise. We leave your home cleaner than we found it. If anything about the install isn’t right within 90 days, we come back and make it right. That’s written, not implied.
