Spray polyurethane foam (SPF) insulation is the gold standard for airtight building envelopes. Unlike batt or blown-in products, spray foam expands on contact to fill every void, crack, and irregular cavity, forming a rigid seal that simultaneously insulates and blocks air movement. Robert & Sons El Segundo Insulation installs both open-cell and closed-cell spray foam depending on your application, budget, and performance goals.
Closed-cell spray foam provides the highest R-value per inch (approximately R-6 to R-7) and acts as a vapor retarder, making it ideal for crawl spaces, rim joists, rooflines, and exterior wall cavities where moisture management is critical. Open-cell foam offers a softer, more flexible install at a lower cost per square foot and excels in interior walls and attic applications where sound dampening is also desired. We evaluate each area of your El Segundo property individually to recommend the right foam type and thickness.
During installation our technicians wear full protective gear and temporarily vacate the space to allow proper off-gassing and cure time before re-entry. The result is a long-lasting, seamless insulation layer that won't sag, settle, or absorb moisture over time—a significant upgrade over traditional fiberglass batts that can degrade and lose performance within a decade.

Common Questions
What is the difference between open-cell and closed-cell spray foam?
Closed-cell spray foam is denser, provides a higher R-value per inch (around R-6.5), and acts as a vapor barrier—ideal for crawl spaces and exterior walls. Open-cell foam is lighter, less expensive, provides around R-3.7 per inch, and is better suited for interior applications where sound reduction is also a goal. We recommend the right type based on your specific area and climate needs.
How long does spray foam insulation last?
Properly installed spray polyurethane foam insulation can last the lifetime of the building—often 80 years or more. It does not absorb water, won't sag or settle, and maintains its R-value without degradation, making it one of the longest-lasting insulation solutions available.
