Evergreen Insulation · Westchester County
Spray foam is the most-searched insulation type in our region — and the most misunderstood. It is genuinely the best tool for some assemblies (rim joists, cathedral ceilings, crawl spaces) and the wrong, expensive tool for others.
Evergreen Insulation installs both closed-cell and open-cell foam where it belongs, and will tell you plainly when cheaper blown-in or batt insulation does the same job for a third of the price.
R-6.5+ per inch, vapor-impermeable, adds structural rigidity — the right call for rim joists, crawl spaces, and moisture-prone assemblies.
Economical air-sealing for larger cavities and sound damping where vapor drive is not a concern.
Foam everywhere is a sales strategy, not building science. We spec it only where it outperforms.

Prep, masking, and professional application with proper ventilation
Cure inspection and trimming
In rim joists, crawl spaces, and cathedral ceilings — usually yes, because nothing else air-seals and insulates those assemblies as well. For open attic floors, blown-in insulation typically delivers the same performance for far less.
Once cured (24 hours), yes. Application requires the space vacated and ventilated — our crews follow the full manufacturer safety protocol.
