Demilec Insulation in Downtown & Central Austin, TX | Super Green Insulation Austin
Stand on the porch of a 1928 craftsman bungalow on Avenue B in Hyde Park on a July afternoon and you’ll feel exactly what we’re talking about. The attic above is pushing 155°F. The open crawl space below is radiating stored ground heat upward through an uninsulated floor assembly. The window AC unit is running flat out — and losing. That sandwich effect, unique to the pier-and-beam housing stock concentrated across Hyde Park and West Campus, is precisely why Demilec’s closed-cell and open-cell spray foam systems were engineered the way they are: to seal and insulate simultaneously, in tight or irregular assemblies that blown fiberglass simply cannot address. At Super Green Insulation Austin, Tom Hopkins and our crew have been solving exactly this kind of problem in serving Downtown & Central Austin, TX for over 16 years. Call us today at (866) 434-2901 to schedule your Demilec assessment.

Why Downtown & Central Austin Residents Choose Us for Demilec Service
Tom Hopkins has led our team for 16-plus years, and a significant portion of that work has been inside the older housing fabric that defines Downtown & Central Austin — pier-and-beam bungalows in Hyde Park, converted brick lofts in the Warehouse District, and dense rental duplexes along West Campus corridors. Our technicians are trained specifically on Demilec product lines, including proper two-component mixing ratios, yield rates, and application temperatures — details that directly affect whether a spray foam job performs at rated R-value or degrades within two seasons.
We carry Demilec-compatible equipment and materials locally, which means we’re not waiting on a regional distributor when you need a re-spray or a repair on an existing foam assembly — learn more about our full Demilec sales & service offerings. With 784 verified reviews averaging 4.9 out of 5 stars, our reputation in Downtown & Central Austin isn’t something we borrowed from a national franchise — it was built job by job, ZIP code by ZIP code, from 78701 through 78712.
Common Demilec Insulation Problems We Solve in Downtown & Central Austin
- Pier-and-beam floor assembly heat gain: Homes in Hyde Park and West Campus suffer a thermal attack from two directions simultaneously — radiant heat from superheated attic assemblies above and ground-conducted heat rising through an open, uninsulated crawl space below. Demilec closed-cell spray foam applied to the underside of the floor decking stops this “sandwich” heat transfer that no HVAC upgrade alone can resolve.
- Vapor drive and moisture infiltration in aging wall cavities: Austin’s IECC Climate Zone 2A designation means aggressive humidity pressure drives moisture inward through balloon-frame and early platform-frame walls that were never designed with a vapor control layer. Demilec’s open-cell Heatlok and closed-cell Agribalance lines create continuous air barriers that address vapor drive at the assembly level, not just at the surface.
- Uninsulated masonry walls in Warehouse District conversions: Converted brick industrial buildings carry significant thermal mass but virtually no R-value in their wall assemblies, and there’s no standard stud cavity to fill with blown insulation. Demilec closed-cell spray foam adheres directly to masonry, adding R-value without requiring furring strips or interior demolition — a critical advantage when working around existing mechanical and electrical runs in loft-style spaces.
- Urban heat island amplification in attic assemblies: The dense urban core of Downtown & Central Austin runs 5–8°F hotter than surrounding suburban areas during peak summer hours, which pushes unshaded attic decking past 150°F — well beyond what standard fiberglass batts were rated to handle when these homes were built. Demilec’s closed-cell roof deck applications create a conditioned or semi-conditioned attic that cuts that radiant load before it reaches living space.
