Insulation Company in Selma, CA
Thistledown Attic Insulation is the insulation company Selma homeowners call when attic temperatures hit 150°F in July and Tule fog settles in for weeks come December. Selma sits in CEC Climate Zone 13, one of California’s most thermally extreme zones, and its housing stock, much of it built between the 1940s and 1970s for agricultural families, predates Title 24 energy standards entirely. That combination makes insulation work here different from anywhere else in the Central Valley, and it’s why we approach every Selma job with the specific conditions of this city in mind. Call (909) 768-6501 any time, day or night, and a live person answers.
Why Selma Homes Are Different
Selma’s housing stock tells the story of the San Joaquin Valley’s agricultural boom. The city’s core is dominated by modest single-family homes built from the 1940s through the 1970s, most constructed with little to no wall insulation and only minimal attic coverage. Builders at the time were working for farming families on tight budgets, and California had no energy code to hold them to. The result is a retrofit market where the performance stakes are unusually high for a city this size.
The climate compounds the problem. Summer highs above 105°F push attic temperatures past 150°F, baking whatever insulation exists. Then from November through February, Tule fog rolls in and holds the valley in cool, moisture-saturated air for days or weeks at a stretch. In Selma’s 1950s and 1960s homes especially, older fiberglass batts absorb that moisture, then compress each summer as they bake. That repeated wet-dry cycle destroys batt loft and R-value faster than in drier markets, which is why so many Selma homeowners notice their heating bills climbing even before they see visible signs of insulation failure. A secondary wave of 1980s and 1990s tract homes on the city’s edges fares better, but even those attics are typically under-insulated by today’s standards. Selma demands both a high-R thermal barrier and careful moisture management, and a single-climate approach simply does not hold up here.
Our Main Selma Services
Selma homeowners call us most often about two services, each with its own detailed page linked below.
Attic Insulation in Selma
Most Selma attics we enter have the original insulation from the home’s construction, compressed, dusty, and well below the R-value today’s climate demands. We remove or top up what’s there and install blown-in or batt insulation matched to the attic’s specific conditions. In Selma’s older agricultural-worker core, that often means addressing moisture damage from decades of Tule fog exposure before new insulation goes in. We lay drop cloths across your hallway, wear shoe covers from the front door to the attic hatch, and leave a photo of the clean-up before we pull away. Attic Insulation in Selma covers pricing, product options, and what to expect on install day.
Spray Foam Insulation in Selma
Spray foam solves two Selma problems at once: it seals the attic against the fog-season moisture that compresses fiberglass batts, and it delivers a higher R-value per inch than traditional materials in the same rafter space. For Selma homes with ductwork running through the attic, spray foam keeps that ductwork inside the conditioned envelope, which matters when summer attic temperatures exceed 150°F. We match the foam, open-cell or closed-cell, to the attic’s ventilation and the family’s needs, and we always provide a written price before any work begins. Spray Foam Insulation in Selma walks through the differences and the typical timeline.
