Pure Eco installs spray foam (SPF) insulation throughout North Hollywood. We use closed-cell and open-cell formulations depending on the application, and we are clear about where spray foam makes sense and where blown-in or batts are the better choice.
Spray foam 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 permanently to surfaces, and delivers both insulation and air sealing in a single application. For specific applications in North Hollywood homes, particularly in raised-foundation properties and homes with HVAC equipment in the attic, nothing else performs as well.
Call Pure Eco today at (877) 870-7998 to schedule your SPF insulation installation.
Crawl space rim joists. North Hollywood has a meaningful number of raised-foundation homes, particularly in the older residential streets south of Magnolia and in the historic areas near Lankershim. The rim joist at the perimeter of the foundation wall is one of the most significant air leakage points in these homes. Closed-cell spray foam applied here seals the gap completely and adds R-value in a location where batts are difficult to fit and retain properly.
Attic roofline applications. In North Hollywood homes where HVAC equipment is located in the attic, the attic temperature on a 100-degree Valley day creates a significant efficiency penalty. An air conditioning system working inside an attic that reaches 150 degrees is losing performance before it even starts. Bringing the attic into the conditioned envelope by spraying the underside of the roof deck with open-cell foam dramatically improves system efficiency and reduces cooling costs in the hottest months.
Attic knee walls. Homes with partially finished attic spaces or bonus rooms above the main floor have knee walls between conditioned and unconditioned spaces. Spray foam applied to the knee wall sheathing creates a continuous air and thermal barrier that batts cannot reliably maintain, particularly in attics that experience the extreme temperature swings of a Valley location.
Around penetrations. Pipe penetrations, electrical runs, HVAC chases, and attic hatch perimeters are all candidates for targeted spray foam as an air sealing measure. In North Hollywood homes with the complex penetration patterns common in properties that have been modified over decades, this targeted approach is often the most efficient path to meaningful air-sealing improvements.

North Hollywood is in California Title 24 Climate Zone 9. Spray foam is not typically used to insulate an entire standard attic floor because the cost per R-value is higher than blown-in insulation for that application. It is specified for targeted locations where its air barrier properties deliver performance that no other product can match.
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 North Hollywood are designed to meet current code requirements. North Hollywood falls under the City of LA building department jurisdiction, and spray foam applications that are part of a larger renovation may require permits.
Closed-cell spray foam 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 foam has an R-value of approximately R-3.6 to 3.8 per inch but installs at greater depth for the same cost, making it practical for roofline applications in North Hollywood homes where attic conditioning is the goal.

Project duration varies with scope. A targeted rim joist application in a North Hollywood crawl space typically takes a few 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. We will give you a specific re-entry time based on your project.

For homes with HVAC equipment in the attic, yes. Moving the attic into the conditioned envelope eliminates the penalty of running a cooling system inside an unconditioned space that reaches 150 degrees. The efficiency improvement is most dramatic in extreme Valley heat.
The home should be vacated during application and for the off-gassing period. We give you a specific re-entry time based on your project scope.
Yes, in most applications. California code requires that spray foam exposed in occupied spaces be covered with a thermal or ignition barrier. Every Pure Eco installation meets this requirement.
Open-cell spray foam has a lifespan of 30 to 50 years, while closed-cell spray foam can last up to 100 years.
Yes. Targeted spray foam at the rim joist, knee walls, and penetrations is a common approach, while blown-in handles the primary attic floor.
