We’ve worked the Converse market long enough to know the difference between a home on Gibbs Sprawl Road near the newer builds and the original 1980s slabs off FM 1518. That local knowledge matters because the insulation failures we find in those two places are completely different animals. Our Spray Foam Insulation team treats every Converse job as its own building-science problem, not a product installation.

Why Topside Attic Insulation New Braunfels Is Converse’s Preferred Spray Foam Insulation Company

Converse homeowners don’t hire contractors who need a GPS to find their neighborhood. We’ve insulated homes from the older sections near Converse City Park to the newer construction around Woodlake and the corridors feeding into Universal City. Our reviews from Converse customers consistently mention two things: we show up when we said we would, and we leave documentation behind that proves what changed.

Response time to Converse averages under an hour from dispatch. That’s not a marketing claim; it’s a function of running crews out of the San Antonio office with Converse as a primary service zone, not an afterthought. When a homeowner calls (830) 243-6352, a live person answers, 24/7. No callback windows measured in business days.

Our local knowledge runs deeper than driving routes. We know which Converse subdivisions were built during the 1989-2005 boom that preceded JBSA-Randolph’s expansion, and which ones went up after 2010 when energy codes finally started tightening. That construction-era difference determines whether we’re dealing with original R-19 batts over unsealed drywall or something slightly better that still fails because the air sealing was never done right.

Our Spray Foam Insulation Services in Converse

Closed-Cell Spray Foam

Closed-cell spray foam is the denser of the two main products, running about 2.0 pounds per cubic foot and delivering R-6.5 to R-7 per inch. In Converse, we specify closed-cell for roof deck applications and any situation where the foam needs to act as both insulation and an air barrier in one pass. The 150°F attic temperatures common on Converse’s east side during July and August will degrade any foam that was shot over a dirty, unsealed deck, so our crews vacuum and seal first. That’s non-negotiable under The Haven Standard.

On military-rental properties near the Randolph corridor, closed-cell on the roof deck solves a specific problem: it creates a conditioned attic that HVAC techs can service without displacing loose insulation every time they climb up. The foam stays put. The R-value stays put. The tenant’s bill stops spiking every August.

Open-Cell Spray Foam

Open-cell runs lighter, about 0.5 pounds per cubic foot, with R-3.5 to R-3.7 per inch. It’s vapor-permeable, which means it allows moisture to pass through rather than trapping it. In Converse’s climate, we use open-cell primarily for above-grade wall cavities in homes where the exterior sheathing is in good condition and the homeowner wants sound dampening along with thermal performance. The product costs less per board foot than closed-cell, but it requires careful application in our Gulf-moisture environment.

Rim Joist Spray Foam

Converse’s slab-on-grade construction from the 1980s through the 2000s left a critical gap at the rim joist, the perimeter band where the exterior walls meet the foundation. These rim joists were typically insulated with a thin piece of fiberglass batt tucked loosely into the cavity, or nothing at all. The result is a thermal bridge that bleeds conditioned air directly to the exterior, plus a moisture collection point where Gulf humidity condenses on the cool concrete.

We spray 2-3 inches of closed-cell foam into Converse rim joist cavities after sealing all penetrations. The foam adheres to the concrete, the sill plate, and the subfloor simultaneously, creating a monolithic air barrier. On homes near Kitty Hawk Road and the older sections off Seguin Road, this single upgrade often produces the most noticeable comfort improvement per dollar spent.

Garage Ceiling Spray Foam

Converse’s tract-home builders frequently positioned bedrooms directly above unconditioned garages, separated by a garage ceiling with minimal or no insulation. In summer, that ceiling becomes a radiant heat source that bakes the room above it. We’ve sprayed garage ceilings in neighborhoods from Live Oak Springs to the areas near Converse North Park, typically applying 5-6 inches of open-cell foam to achieve R-19+ and a complete air seal. The bedroom above stops being the hottest room in the house.

Spray Foam Roof Deck

The spray foam roof deck application is our most specified upgrade for Converse’s 1980s-2000s stock. Instead of insulating the attic floor, we insulate the underside of the roof deck itself, converting the attic from a vented, unconditioned space to an unvented, conditioned space. This eliminates the 150°F temperature differential that makes Converse attics so punishing on HVAC systems and ductwork.

On a recent job near the Randolph corridor, our crew shot 2 inches of closed-cell against the roof deck and gable ends of a 1989 slab home. The before-and-after blower-door test dropped from 3,800 CFM50 to 2,100 CFM50. The homeowner received the written scope, the photo record, and the blower-door documentation before anyone packed up.

Trusted Brands We Service in Converse

We source spray foam materials from Demilec, Johns Manville, and Owens Corning, among others. No proprietary lock-in means we specify the right product for the Converse job rather than pushing whatever our supplier needs to move. Demilec’s heat-resistant formulations perform well in our 150°F attic conditions. Johns Manville’s open-cell products offer consistent expansion ratios for wall cavities. Owens Corning’s closed-cell line provides the density and adhesion we want for rim joist and roof deck work. We stock local inventory for Converse jobs to avoid supply-chain delays that push schedules into the next billing cycle.

Common Spray Foam Insulation Problems We See in Converse Homes

• HVAC-displaced batts over bare drywall. On the military-rental streets east of JBSA-Randolph, we regularly pull attic hatches to find original R-19 batts shoved flat against the sides of flex-duct runs, with bare drywall in the center of the field. Four years of rotating HVAC crews wrestling ductwork across the attic will do that. The homeowner sees intact insulation from the hatch; the infrared camera sees 140°F surface temperatures on the ceiling below.
• Gulf-moisture vapor drive degrading fiberglass. Converse’s proximity to Gulf moisture creates vapor drive conditions that push humid attic air through unsealed top plates. Fiberglass batts absorb that moisture, collapse against the drywall, and read far below even their thin original R-value. The batts look fine from the hatch. They’re not.
• Spray foam applied over unsealed, dirty decks. We’ve been called to fix other contractors’ work where open-cell foam was shot directly over years of dust, rodent debris, and compressed old insulation. The foam bonds to the contamination layer instead of the substrate. Air leaks straight through. In Converse’s 150°F attics, that failure mode accelerates.
• Original slab-home rim joists left open. The 1980s and 1990s tract homes from Woodlake to the areas near Converse City Park were built with uninsulated rim joists as standard practice. Conditioned air leaks continuously through these perimeter bands, and the cold concrete surface collects condensation that supports mold growth in the crawl-adjacent wall cavities.
