They removed all the old insulation and rodent waste thoroughly, then installed spray foam insulation that has completely transformed the space. Afterward, I sealed the attic, which will help lower our energy bills and keep the temperature stable. What impressed me most was how clean and non-toxic the process was, they left the air fresh and the entire area spotless.

Mastering the Thermal Envelope in Central Texas
Effective insulation goes far beyond simply rolling out material in an attic; it is about building science and establishing a complete thermal barrier. In the New Braunfels area, where humidity and heat interact with your home’s structure, gaps in your insulation can lead to moisture intrusion, allergen buildup, and significant energy loss. By treating the “whole house” as a system, we implement solutions that seal air leaks and stabilize indoor temperatures.

Mini Case Study: The River Chase Retrofit
Challenge: A family in the River Chase community of New Braunfels reported that their upstairs bedrooms were 10 degrees hotter than the ground floor, forcing their AC unit to run continuously without reaching the set temperature.
Solution: Stellrr conducted a thermal audit and found that the existing fiberglass batting had settled, leaving significant air gaps. We performed a complete extraction of the old material and installed 6 inches of open-cell spray foam to the roof deck, sealing the attic completely.
Result: The attic temperature dropped by over 30 degrees immediately. The homeowners reported a balanced temperature across all floors and a 25% reduction in their energy bill during the first month of summer operation.

Common Questions About Insulation & Efficiency
What is the difference between open-cell and closed-cell spray foam?
Open-cell foam is lighter, less expensive, and excellent for soundproofing and interior insulation, as it allows for some moisture permeability. Closed-cell foam is much denser, acts as a complete vapor barrier, provides structural rigidity, and offers a higher R-value per inch, making it ideal for exterior walls and humid areas.
Will spray foam insulation really lower my utility bills in New Braunfels?
Yes, significantly. Traditional insulation often leaves gaps that allow air leakage, forcing your HVAC system to work harder. Spray foam creates an air-tight seal that prevents conditioned air from escaping and hot Texas air from entering, typically reducing energy consumption by 20% to 50%.
Is spray foam insulation safe for my family and pets?
When installed by certified professionals like the Stellrr team, spray foam is perfectly safe. Once the foam has cured (usually within 24 to 48 hours), it becomes inert and no longer off-gases. We ensure proper ventilation during the installation process to maintain safety standards.
Can you remove old, damaged insulation before installing new foam?
Absolutely. In fact, removing old insulation is often necessary, especially if rodents, water damage, or mold have compromised it. We provide full-service removal and disposal to ensure the substrate is clean and ready for a high-performance application.
How does insulation help with humidity control in Central Texas?
In humid climates, moisture enters homes through air leaks. By creating an air barrier with spray foam, we stop the infiltration of humid outdoor air. This allows your AC unit to dehumidify the indoor air more efficiently, reducing the risk of mold growth and increasing personal comfort.
