Demilec Insulation Service in Austin, TX | Super Green Insulation Austin
If your home or business relies on Demilec spray foam insulation and you’re seeing signs of separation, moisture infiltration, or thermal performance loss, you need a local team that actually knows the product — not a generalist who’s guessing. Super Green Insulation Austin operates as an independent Demilec service provider with over 16 years of hands-on experience diagnosing and correcting spray foam issues across Austin and surrounding communities. Tom Hopkins and our crew have worked with Demilec systems in hundreds of Central Texas attics, crawlspaces, and wall cavities. Call us today at (866) 434-2901.
Why Trust Super Green Insulation Austin for Your Demilec Insulation?
Demilec manufactures some of the most performance-consistent spray foam systems on the market — Heatlok, Agribalance, and their 2-lb closed-cell lines have earned real loyalty among Austin-area builders and homeowners. But even well-installed Demilec foam can degrade when Austin’s brutal summer heat cycles — we’re talking sustained 100°F+ roof deck temperatures from June through September — stress the adhesion between foam and substrate over years of expansion and contraction.
Tom Hopkins and our technicians stay current on Demilec’s mixing ratio specifications, substrate compatibility requirements, and cure-time protocols that govern whether a repair holds long-term or fails again in 18 months. We source OEM-compatible materials that meet Demilec’s density and R-value tolerances, so your existing system’s thermal performance is restored to spec — not just patched cosmetically. We’re not a factory-authorized dealer, but our independent expertise is grounded in real Demilec system experience built across more than 784 verified Austin-area jobs averaging a 4.9-star rating.
Common Demilec Insulation Problems We Fix in Austin
- Heatlok HFO adhesion failure at rooflines: In Austin’s Barton Hills and Travis Heights neighborhoods — where steep-pitch roofs absorb intense afternoon sun — we regularly see Heatlok HFO pulling away from OSB sheathing along ridge lines. The closed-cell foam loses its mechanical bond when substrate moisture content was slightly elevated at the time of original installation; we cut out the failed section, prep the substrate to proper moisture levels, and re-spray to Demilec’s published 2 lb/ft³ density spec.
- Agribalance open-cell shrinkage in unconditioned attics: Agribalance’s soy-based open-cell formula is an excellent performer when installed in conditioned spaces, but Austin homeowners who’ve had it sprayed in unconditioned attics sometimes discover dimensional shrinkage after two or three summer seasons. We assess the extent, determine whether a flash-coat of closed-cell foam over the affected area restores air-sealing performance, or whether full removal and reinstallation is warranted.
- Off-ratio spray causing soft, tacky foam surfaces: A mixing ratio error during original installation — even a slight imbalance between Demilec’s A-side isocyanate and B-side resin — produces foam that never fully cures. You’ll notice it as a persistent tacky or greasy feel and a noticeably lower compressive strength. We identify off-ratio sections through visual inspection and simple compressive testing, then remove and replace the compromised material.
- Vapor drive condensation in South Austin slab foundations: South Austin homes built on post-tension slabs with crawlspace encapsulation using Demilec’s closed-cell product sometimes develop condensation pockets when the foam was applied too thin — under the 2-inch threshold needed to act as a Class II vapor retarder in Austin’s mixed-humid climate (IECC Zone 2A). We add a supplemental layer to bring the assembly to effective vapor control thickness.
- UV degradation on exposed exterior foam: Any Demilec foam left exposed to Austin’s UV load without a protective coating will chalk and erode within 12 to 18 months. We see this most often on outbuildings in East Austin and on rim joist applications where the foam is visible from the exterior. Our repair protocol includes mechanical removal of compromised material and application of an elastomeric UV-barrier coating rated for Central Texas solar exposure.
Our Demilec Service Process
Every Demilec service call in Austin follows a structured protocol that keeps your repair warranty-defensible and your system performing to spec.
Step 1 — Thermal Diagnostic: We use infrared thermography to map the actual thermal boundary of your existing Demilec installation. This isn’t guesswork — IR imaging shows us precisely where the insulation is underperforming before we open a single wall cavity or attic access panel.
Step 2 — Substrate Assessment: Before any Demilec foam goes down, we measure substrate moisture content with a calibrated pin meter. Demilec’s installation guidelines require substrate moisture below 19% for wood and surface temperatures between 50°F and 120°F. Austin’s humidity cycles mean these conditions aren’t always met — we don’t spray until they are.
Step 3 — OEM-Compatible Repair or Reinstallation: We apply Demilec-compatible foam to the correct density and thickness, staged in lifts that don’t exceed Demilec’s published single-pass thickness limits to avoid exothermic heat damage.
Step 4 — Post-Installation Verification: We re-run the IR scan after the foam cures to confirm the thermal gap is resolved, document the work with photos, and provide you a written service summary you can retain alongside your original Demilec installation records.

We Also Service These Brands
Demilec is our featured specialty on this page, but Super Green Insulation Austin services and installs insulation from Owens Corning, Johns Manville, Knauf, and Rockwool as well.

FAQs — Demilec Insulation Service in Austin
We are an independent service provider, not a factory-authorized Demilec dealer or affiliate.

We disclose this clearly because we believe you deserve honest answers.
We use OEM-compatible materials that meet or match Demilec’s published density, R-value, and adhesion specifications. For foam replacement work, we source Demilec or Demilec-equivalent product formulations to ensure the repair integrates properly with the existing system.
