Pure Eco installs spray foam insulation throughout Burbank. We use closed-cell and open-cell formulations depending on the application, and we approach every project with a clear understanding of where spray foam makes sense and where other products are the better choice.
Spray polyurethane foam (SPF) insulation occupies a different category than other insulation products. Where blown-in cellulose or fiberglass batts add thermal resistance to an existing air barrier, spray foam creates the air barrier itself. It expands on contact to fill every gap, crack, and penetration it touches, bonds to surfaces, and delivers both insulation and air sealing in a single application. For specific applications in Burbank homes, nothing else performs as well. Because spray foam is a highly specialized application, you need a contractor who prioritizes technical precision and professional accountability.
As a licensed contractor (Lic #993589), Pure Eco backs every spray foam project with a 100% satisfaction guarantee. We provide free consultations and clear estimates before any work begins. You receive honest advice with no pushy sales tactics. Our experienced local technicians deliver fast, professional results that focus on your air quality and long-term energy savings.

Burbank is in California Title 24 Climate Zone 9, where the R-value targets for attic insulation are R-38 minimum and R-49 recommended. Spray foam is not typically used to insulate an entire standard attic floor because its cost per R-value is higher than that of blown-in insulation for that application. Instead, it is specified for targeted locations where its air-barrier properties deliver performance unmatched by any other product.
Burbank Water and Power may offer rebates for spray foam installations when they are part of a broader energy-efficiency upgrade. BWP is an independent municipal utility with its own rebate programs.
California building code requires that spray foam exposed in occupied spaces be covered with a thermal or ignition barrier. All Pure Eco spray foam installations in Burbank are designed to meet current code requirements.
Closed-cell spray polyurethane foam (ccSPF) has an R-value of approximately R-6 to R-7 per inch and creates a vapor retarder in addition to an air barrier. It is the appropriate choice for crawl space rim joists and exterior-facing applications.
Open-cell Spray polyurethane foam (ocSPF) has an R-value of approximately R-3.6 to R-3.8 per inch but installs at greater depth for the same cost, making it practical for roofline applications. It is vapor-permeable, which makes it appropriate for assemblies where drying potential needs to be maintained.
Spray foam projects vary in duration depending on the scope. A targeted rim joist application in a Burbank crawl space typically takes two to four hours. A full roofline application in an attic can take a full day or longer. Occupants should be out of the sprayed areas during application and for two to eight hours after, depending on the product and volume applied. We will give you a specific re-entry time based on your project scope.

For the right applications, yes. Closed-cell spray foam at a crawl space rim joist or open-cell at a roofline delivers performance that no other product can match in those locations. For a standard open attic floor, blown-in is typically the better value.
The home should be vacated during application and for the off-gassing period afterward. We give you a specific re-entry time based on your project.
Yes, in most applications. California building code requires that spray foam exposed in occupied spaces be covered with a thermal barrier. Every Pure Eco installation is designed to be code-compliant.
Open-cell typically lasts 30–50 years, while closed-cell spray foam lasts 80–100 years.
Yes. Spray foam is frequently used in targeted applications, such as the rim joist and knee walls, while blown-in handles the primary attic floor.
