What is the difference between closed cell and open cell spray foam?

Closed cell spray foam (2-lb density) achieves R-6.5 per inch, acts as a vapor retarder, and adds structural strength -- it is the best choice for crawl spaces, basements, rim joists, and exterior walls in Charlotte's climate. Open cell spray foam (0.5-lb density) achieves R-3.7 per inch, is more flexible and better at sound control, and is commonly used in attics and interior walls. Our estimators will recommend the right type for each application in your home.

How long does spray foam insulation last?

Properly installed spray polyurethane foam (SPF) insulation can last the lifetime of your home -- typically 30 to 80 years. It does not sag, settle, or absorb moisture like fiberglass batt insulation. This permanence is one reason spray foam delivers a strong return on investment over time. Charlotte Expert backs all installations with a workmanship warranty.

Will spray foam insulation lower my energy bills?

Yes. Spray foam is the most effective insulation type for reducing energy bills because it both insulates and air seals in a single application. Charlotte homeowners typically see 30 to 50 percent reductions in heating and cooling costs after a full thermal envelope spray foam application. The tight air barrier prevents the conditioned air loss that wastes energy in traditionally insulated homes.

Is spray foam insulation safe for my family?

Once cured -- typically 24 hours after application -- spray foam insulation is inert, non-toxic, and completely safe. During application, our crews use full PPE including supplied-air respirators, and we ask homeowners to vacate the area during application and for 24 hours afterward. We follow all SPFA (Spray Polyurethane Foam Alliance) safety protocols on every job.
