Blown-in insulation is a cost effective way to improve the energy efficiency, heating or cooling, and air quality of the attic in your home. It involves using a special machine to blow loose insulation material, such as fiberglass, into the attic space or walls.
At Superior Attic, we use Knauf Jet Stream Ultra Blowing Wool—a high-performance, non-combustible fiberglass insulation. This premium product is BIBS-approved, dense-packed without settling, and delivers excellent thermal efficiency while using a high percentage of recycled content. It’s the trusted choice for homeowners who want long-lasting comfort, energy savings, and sustainability.
Blown-in insulation helps to keep a home cool in the summer and warm in the winter by preventing heat from escaping or entering through the roof. In addition to its energy-saving benefits, blown-in attic insulation also helps to reduce noise pollution. For homeowners in the Dallas-Fort Worth area, blown-in insulation is an excellent investment in their home’s comfort and value, as well as a way to save money on energy bills and expand the lifetime of your HVAC components.
We use Jet Stream Ultra Blowing Wool by Knauf—non-combustible fiberglass, BIBS-approved, dense-packs without settling, and delivers excellent thermal efficiency. Made with high recycled content.

Most blown-in insulation projects can be completed in just 1–2 days.
While savings vary by home size, climate, and your current insulation levels, most homeowners see energy bill reductions of 15–30% after installing blown-in attic insulation.
R-value is a measure of insulation’s ability to resist heat flow. The higher the R-value, the better the insulation keeps heat from escaping in winter and entering in summer. Attics with higher R-values are more energy-efficient, more comfortable year-round, and reduce the workload on your HVAC system.
In Texas, building energy codes require R-38 attic insulation in most regions of the state. This is the standard for code compliance and ensures your home meets basic energy efficiency requirements.
At Superior Attic, we often recommend going beyond code (R-49 to R-60) for improved comfort, energy savings, and long-term protection against rising utility costs.
It really depends on your home. Spray foam generally offers higher performance because it air seals and insulates in one step, but that doesn’t mean it’s always the right choice.
The best solution depends on factors like the current state of your attic system, existing components (ductwork, ventilation, wiring), and the specific comfort or energy issues your home is facing.
The best way to know what will work for you is to schedule a free inspection and estimate with our team. We’ll evaluate your attic and recommend the insulation option that will give you the greatest comfort and efficiency for your home.
The difference comes down to installation method and application:
Both are fiberglass products and help improve energy efficiency, but blown-in insulation usually provides better coverage in attics, while batts are better suited for walls and angled ceiling spaces.
Yes. The fiberglass blown-in insulation we install, Jet Stream Ultra, is naturally non-combustible and fire-resistant. That means it won’t burn or contribute fuel if a fire occurs. While it adds an extra layer of safety compared to some other materials, it’s important to remember that insulation alone does not make a home fireproof. Safe installation and proper clearances around heat sources are always essential.
At Superior Attic, we don’t just add insulation—we prepare your attic the right way to make sure it performs at its best. Before installing blown-in insulation, we:
This process ensures your attic is clean, sealed, and insulated to maximize comfort and energy savings.
We used Superior Attic to install new insulation. Blake was our advisor, he was professional; he communicated everything that was to be done and it got done on time. They did a fantastic job! I would recommend them to anyone based on our experience.
Very professional and convenient. Did a great job installing radiant barrier, insulation and solar fan. Highly recommend.
Probably one of the most professional companies I’ve worked with yet. Quick to deliver a quote and they finished the job in a matter of days. 10/10 recommend.
Superior Attic removed old insulation and installed new blown-in insulation. They arrived on time and stayed within schedule. Work appears to be high quality, and the PM stopped by to check the finished project. Overall I am pleased with their service.
