Spray Foam Insulation in Prince's Bay, NY

Spray foam insulation in Prince's Bay often goes into houses near Raritan Bay. Wikipedia describes the area as first a fishing village famous for its oysters, then a popular location for summer homes, many owned by residents of other boroughs, until the surrounding waters became polluted in the mid-20th century. In recent decades the waterfront has been redeveloped with many upscale single-family homes.

Older houses

Some very old houses remain. Wikipedia notes that the Abraham Manee House, with beams dating to 1670, is among the oldest in the five boroughs, and parts of the Seguine Mansion date to the same era. Most older houses here are far younger but still predate modern insulation. They need walls filled, attics sealed and lower levels checked for moisture.

Newer waterfront houses

Larger new homes near the water usually have better wall insulation but often have complex roofs, vaulted ceilings and big attics. Closed-cell foam under the roof deck handles vaulted ceilings well. Air sealing matters on exposed lots facing the bay, where wind is stronger.

Damp air from the bay

Humid air comes off the water all summer. Central Park's normals show July and August dew points near 62F, and conditions near the bay are at least as humid. Crawl spaces and basements here benefit from closed-cell foam and vapor control. Near the shore, we also check flood maps: below the base flood elevation in a mapped flood zone, FEMA allows only Class 4 and 5 flood damage-resistant materials.

Mostly owner-occupied

Wikipedia's census summary for the Annadale-Huguenot-Prince's Bay-Woodrow tabulation area shows 26.3% of occupied units are rented.
