Stellrr Insulation & Spray Foam, a residential and commercial insulation contractor based in Leander, TX, has extended its service area to include additional communities across the central Texas region. The expansion allows the company to provide insulation installation and energy efficiency services to a broader customer base in the growing metropolitan corridor.

The property owners in Texas face increasing energy costs and seek methods to reduce heating and cooling expenses. According to the U.S. Energy Information Administration, Texas residential customers paid an average of 14.6 cents per kilowatt-hour in 2024, with cooling costs accounting for a significant portion of household energy consumption in the state's hot climate.

Shawn Mansur, owner of Stellrr Insulation & Spray Foam in Leander, TX, explained the reasoning behind the expansion. "We've seen consistent demand from homeowners and business owners in surrounding areas who need insulation upgrades or new installations," Mansur said. "By extending our coverage, we're able to respond to service requests more efficiently and help property owners address energy loss issues that affect their monthly utility bills."

Data from the Department of Energy indicates that heating and cooling account for approximately 50 to 70 percent of energy use in a typical American home. Air leakage through gaps, cracks, and poorly insulated areas can increase energy consumption by 25 to 40 percent annually. Proper insulation installation reduces the workload on HVAC systems and helps maintain consistent indoor temperatures throughout the year.

The insulation industry has seen steady growth in recent years, driven by building code updates, energy efficiency incentives, and increased awareness of indoor air quality. The North American Insulation Manufacturers Association reported that the proper insulation of residential buildings could reduce carbon emissions by up to 780 million tons over the next decade. In Texas specifically, where summer temperatures regularly exceed 95 degrees Fahrenheit, adequate attic insulation can reduce cooling costs by 10 to 50 percent, depending on existing conditions.

Leander and the surrounding central Texas communities have experienced rapid population growth over the past decade. The U.S. Census Bureau data shows that Williamson County, where Leander is located, grew by more than 50 percent between 2010 and 2020. This expansion has led to increased construction of both residential and commercial properties, creating ongoing demand for insulation contractors who can serve new builds as well as retrofit existing structures.

Beyond energy savings, insulation affects indoor environmental quality. The Environmental Protection Agency notes that proper insulation and air sealing can reduce the infiltration of outdoor pollutants, allergens, and humidity into indoor spaces. In climates with high humidity levels, inadequate insulation can lead to condensation problems, which may contribute to mold growth and structural damage over time.

The Building Performance Institute reports that air sealing and insulation upgrades are among the most cost-effective energy efficiency improvements available to property owners. Return on investment varies by region and existing conditions, but in hot climates like central Texas, improvements to attic insulation typically show measurable reductions in cooling costs within the first year of installation.

Central Texas falls within Climate Zone 2, as defined by the International Energy Conservation Code. This designation influences minimum insulation requirements for new construction and renovation projects. Attic insulation in this zone typically requires an R-value between R-30 and R-49, depending on the specific code year and building type. Walls generally require R-13 to R-15, while floors over unconditioned spaces need R-13 to R-19.

Insulation installation requires specialized equipment, training, and knowledge of building science principles. Spray foam application, in particular, involves chemical mixing, proper ventilation protocols, and surface preparation to ensure adequate adhesion and performance. Industry certifications and manufacturer training programs help ensure that installers follow best practices for safety and quality.

The insulation sector is subject to various building codes, manufacturer specifications, and safety regulations. Contractors must stay current with changes to energy codes, product formulations, and installation techniques. The Spray Polyurethane Foam Alliance and the Insulation Contractors Association of America provide ongoing education and certification programs for industry professionals.

Property owners considering insulation upgrades should evaluate current conditions through an energy assessment or inspection. Thermal imaging cameras can identify areas of heat loss or air infiltration that may not be visible during a standard visual inspection. These assessments help determine which areas would benefit most from insulation improvements and what type of insulation would be most appropriate.

Financing options and utility rebate programs are available in many areas to offset the upfront cost of insulation projects. Some utility companies offer energy audits and rebates for customers who complete qualifying upgrades. Federal tax credits for energy efficiency improvements have also been available in recent years, subject to specific criteria and legislative changes.
