A home’s structure is a large component of energy efficiency. Air flows in and out of a building through every crack, crevice and hole. Roughly 33% of the energy used in a residential or commercial space is lost to air infiltration. Spray foam insulation NYC seals the building envelope to prevent conditioned indoor air from escaping and unconditioned outdoor air from entering. This helps reduce extreme temperature variations and minimizes the strain on mechanical systems to heat and cool buildings.

Unlike fiberglass or cellulose-quality Insulation, spray foam is a liquid that’s applied on-site. When mixed with catalysts, it expands to fill voids in between studs and joists for a tight, custom fit. It’s also easy to apply in tricky spaces, such as overhangs, knee walls, and bonus rooms.

Enhancing Comfort and Savings: The Impact of Spray Foam Insulation

There are two main types of spray foam: open and closed cells. Open-cell foam is softer and more flexible because it’s made with cells that are deliberately left open rather than fully encapsulated. It’s typically used during the rough-in stage to fill voids and gaps around plumbing and electrical wiring.

Closed-cell foam is more durable and provides better insulating performance because it’s physically stronger and creates an effective vapor barrier. However, it’s more expensive than open-cell foam. When deciding whether to DIY or hire a professional installer, homeowners should consider their skill level and the size of the project. A qualified professional is best equipped to ensure consistent coverage and expansion as well as provide a HERS Inspection (HERS Verifier or HERS Rating). A HERS inspection is conducted by a third-party technician who ensures that the insulated framing meets a standard set by the California Energy Commission. This allows a single-family residence to receive its full energy modeling credit.
