Demilec Insulation in North Central Austin, TX

Demilec Insulation in North Central Austin, TX | Super Green Insulation Austin

Pull back the attic hatch on a 1958 ranch home in Allandale and you’re likely looking at a scene that’s become familiar to Tom Hopkins and our crew after 16 years working North Central Austin’s mid-century housing stock: shredded kraft-faced batts pushed into corners by a squirrel that’s been living rent-free up there for two seasons, a crawl space open to August air from below, and 2×4 wall cavities that haven’t seen an ounce of insulation since the Eisenhower administration. That’s the three-envelope problem — attic, walls, and underfloor — and it’s the defining challenge of North Central Austin homes that no generic insulation page written for Round Rock will ever address. We solve it with Demilec spray foam and blown-in systems sized and sequenced for exactly this housing stock, and our broader Insulation Installation in North Central Austin services cover every assembly type we encounter. Call us at (866) 434-2901 to schedule your assessment.

Common Demilec Insulation Problems We Solve in North Central Austin

• Animal-contaminated attic insulation requiring full remediation before foam application: In Allandale and Crestview, aging wood soffits and fascia on mid-century homes are a well-documented entry point for squirrels and opossums — both thriving in North Central Austin’s dense urban tree canopy. We routinely remove shredded, soiled, compacted batt material before a single inch of Demilec Heatlok or Sealection 500 goes in, because applying over contaminated substrate undermines both adhesion and air-sealing performance.
• Empty or near-zero-R wall cavities in postwar 2×4 framing: Homes built across North Central Austin between 1945 and 1970 were constructed well before Texas adopted meaningful energy codes, leaving wall cavities either completely empty or holding flattened original batts with negligible R-value. Demilec’s open-cell Sealection 500 is ideal for dense-pack retrofit into these 2×4 bays through minimally invasive drill-and-fill access, restoring thermal resistance without requiring exterior cladding removal.
• Exposed pier-and-beam crawl spaces losing conditioned air through the floor system: Unlike the slab-on-grade construction common in newer Austin suburbs, the pier-and-beam foundations prevalent throughout North Central Austin leave the entire floor assembly exposed to untempered outside air. During Austin’s 90-plus consecutive days above 90°F, unconditioned crawl spaces push heat directly into the living space through an uninsulated subfloor — Demilec closed-cell foam applied to the underside of the floor deck stops that heat transfer at the source.
• Settled, degraded fiberglass batts in 1970s–80s apartment stock along Rundberg and 78753: The garden-style apartment complexes that run through Rundberg and parts of the 78753 corridor were built with fiberglass batt insulation that has, in many cases, settled and compressed over 40-plus years into a fraction of its original thickness. Austin’s periodic blue norther cold fronts — capable of dropping temperatures 40°F in hours — cycle vapor pressure across these aging envelopes in ways they were never engineered to handle, and Demilec blown-in products restore the R-value lost to decades of gravity and moisture cycling.
