Pure Eco installs blown-in insulation throughout Burbank using professional-grade equipment and materials rated for California Climate Zone 9 requirements. We work with blown-in cellulose and fiberglass materials.
Blown-in insulation is the most practical and effective solution for most Burbank attics. It is installed faster than batts, fills irregular framing and tight spaces better, settles to a more uniform coverage, and is the standard method for topping up existing insulation without a full removal project. For Burbank homes built across four decades of different construction eras, blown-in handles the variety of attic geometries better than any other product. Maximize your attic’s potential with a team that values your time and your budget.
Pure Eco is a licensed insulation specialist (Lic #993589) providing expert blown-in services throughout Burbank. We offer immediate phone responses, free consultations, and a 100% satisfaction guarantee to ensure your project is completed correctly. Our experienced team focuses on your comfort with an honest, no-pressure approach tailored to your home’s specific needs.

Burbank attics are not uniform. The postwar ranch homes in the Rancho area have relatively open truss-framed attics with standard joist spacing, but they also have HVAC equipment, ductwork, and electrical runs that create obstructions where batts cannot be fitted properly. The older Craftsman and Spanish Revival homes near downtown Burbank and Magnolia Park have low-slope roof sections and tight eave runs where batt installation is difficult or impossible to do correctly. The hillside homes near the Verdugo Mountains have attic geometries shaped by the lot grade rather than a standard grid.
Blown-in insulation handles all of these conditions. The loose-fill material is conveyed through a hose and deposited in place, flowing around obstructions and filling irregular cavities to a uniform depth. It is also the standard method for adding insulation over existing material when a full removal is not needed.

Burbank falls in California Title 24 Climate Zone 9, which requires a minimum attic insulation R-value of R-38 for existing homes and strongly recommends R-49 as the performance target. Most Burbank homes built before 1980 fall well below that range. Blown-in insulation is the most efficient method for closing that gap, whether installed over existing material or as a full replacement after removal.
Burbank Water and Power offers energy efficiency rebates for qualifying insulation upgrades. Because BWP is an independent municipal utility separate from LADWP and SCE, its rebate programs, eligibility criteria, and amounts are unique to Burbank.
The construction era of your Burbank home affects the blown-in approach. Homes built in the 1940s and 1950s often have non-standard joist depths and spacing, making blown-in insulation the only practical choice. Homes from the 1960s and 1970s typically have more standardized framing but may have existing insulation that needs evaluation before adding material on top. In all cases, the blown-in installation is calibrated to the specific depth required to achieve the target R-value for this climate zone.
Blown-in cellulose is our most commonly installed product in Burbank attics. Made from recycled paper fiber treated with borate compounds for fire resistance and pest deterrence, it installs at a higher density than fiberglass and is more resistant to air movement through the insulation layer.
Blown-in fiberglass is specified where moisture resistance is a priority, such as attics with a history of humidity issues or homes near the hillside areas where temperature differentials create condensation risk.
A blown-in insulation installation in a standard Burbank home takes a few hours. The blower unit stays outside or in the truck, with only the hose and installer entering the attic. Living areas are not affected. When installation is complete we remove all equipment, clean up any material near the access point, and walk you through documentation of the completed installation.

California Title 24 sets R-38 as the minimum for existing homes in Climate Zone 9 and R-49 as the recommended performance target. For a city as hot as Burbank in summer, R-49 is worth targeting.
Yes, provided the existing batts are in acceptable condition. No pest contamination, no moisture damage, no significant mold. Blown-in cellulose or fiberglass can be installed directly over intact existing batts.
All blown-in products settle somewhat in the first few months after installation. We account for this by installing to a depth above the target R-value. The final settled depth delivers the rated performance.
Blown-in is a loose-fill product installed in open attic cavities. Spray foam is a liquid that expands and adheres to surfaces, creating an air barrier as well as insulation. We use each product where it performs best.
No. We install baffles at eave vents to maintain the ventilation channel and verify that all attic ventilation pathways are unobstructed after installation.
