Johns Manville Insulation in South Austin, TX | Super Green Insulation Austin
South Austin’s housing stock throws curveballs that most insulation crews aren’t prepared for — and that’s exactly why Tom Hopkins built Super Green Insulation Austin around deep local knowledge and proven materials.

Why South Austin Residents Choose Us for Johns Manville Service
South Austin is not a one-size-fits-all insulation market, and we’ve never treated it that way. Tom Hopkins and our crew have spent 16-plus years working in the pier-and-beam bungalows of Bouldin Creek, the ranch homes of 78745, and every housing type in between. We stock Johns Manville batts, rolls, and board products locally so we’re not waiting on a distributor when your project is ready to move. Our 784 verified reviews averaging 4.9 out of 5 stars aren’t from some far-flung suburb — the overwhelming majority come from South Austin service area homeowners who had specific, complicated problems and needed them solved right the first time. As an independent Johns Manville service provider, we’re not manufacturer-affiliated, which means our loyalty is to your project outcome, not to a sales quota.
Common Johns Manville Insulation Problems We Solve in South Austin
- Settled or absent attic insulation in 1940s–1960s bungalows: In the 78704 corridor — Travis Heights, Zilker, and surrounding blocks — we regularly pull back attic hatches and find either nothing at all or a thin, compressed layer of original rock wool that measures R-4 at best. A Johns Manville Climate Pro blown fiberglass install to current R-38 code can cut summer cooling loads dramatically in these homes, where attic temps routinely push past 140°F.
- Uninsulated underfloor crawl spaces letting cold and heat transfer through hardwood floors: The pier-and-beam crawl spaces in Bouldin Creek typically sit just 18 to 24 inches off grade with exposed dirt and no ground vapor barrier — in summer, radiant heat bakes up through the floor; in a hard freeze like February 2021’s Winter Storm Uri, pipes drop to outdoor ambient temperature within hours. We keep both Johns Manville open-cell spray foam and rigid foam board on the truck specifically for these underfloor envelopes.
- Hollow wall cavities in wood-frame homes mid-renovation: Contractors flipping bungalows in the SoCo and Bouldin Creek neighborhoods frequently discover that original wall framing was never filled — or was filled with newspaper and sawdust. Johns Manville Spider blown-in wall insulation lets us retrofit to R-15 in a 2×4 wall without opening up finished drywall on both sides, which matters enormously on historic or recently updated interiors.
- Degraded fiberglass batts in 1970s–1990s ranch homes farther south: In 78745 and 78748, the slab-on-grade ranches from this era commonly have original fiberglass batts that have absorbed moisture, settled, and lost significant R-value. South Austin’s position just east of the Balcones Escarpment places it in a more humid coastal-plain air mass than the drier Hill Country to the west, which accelerates batt degradation when vapor retarders were originally installed incorrectly — a mistake we diagnose and correct every week.
Johns Manville Models & Products We Service in South Austin
We work with the full Johns Manville residential product lineup. For attic installs, that means Climate Pro blown fiberglass and Formaldehyde-free batt insulation in R-19 through R-60 configurations. For underfloor and crawl space work — which is a significant part of our South Austin volume — we use Johns Manville rigid foam board and coordinate with spray foam applications, and our team also handles Attic & Crawl Space Restoration in South Austin when existing materials need to be removed or remediated before new insulation goes in. Wall retrofit projects in older bungalows call for Spider blown-in insulation, which we stock and install regularly across the 78704, 78741, and 78745 ZIP codes.

Frequently Asked Questions About Johns Manville Insulation in South Austin
Yes — a pier-and-beam home in South Austin requires insulation work across three separate building envelopes: the attic, the wall cavities, and the underfloor crawl space. A slab-on-grade home eliminates the underfloor problem entirely. In practical terms, a full retrofit of a 1950s bungalow in Travis Heights or Zilker typically involves two to three times the scope of a comparable-square-footage slab ranch in 78748, and the materials chosen for the crawl space have to account for South Austin’s elevated humidity to avoid vapor-drive condensation issues down the line.
In South Austin’s current market, attic-only blown fiberglass installs in a 1,400–1,800 sq ft home generally run between $1,200 and $2,400 depending on current R-value, accessibility, and depth required to reach R-38. Adding an underfloor crawl space component — common in 78704 pier-and-beam homes — typically adds $800 to $1,800 to the project. Wall blown-in insulation for a full bungalow exterior ranges from $1,500 to $3,200 depending on the number of wall cavities and access method. These are South Austin market figures as of early 2026; we provide firm written quotes after every free assessment.
The clearest sign is a heating bill that spiked far above your neighbors’ during extreme cold — but the more telling diagnostic is a thermal scan during our free assessment. In the older bungalows we inspect in Bouldin Creek and Travis Heights, it’s common to find floor cavities that are effectively open to outdoor air, attic bypasses around plumbing chases, and wall sections where original insulation has pulled away from framing. If your home was built before 1975 and you haven’t had an insulation audit, there’s a very good chance it’s performing well below modern code.
