Spray Foam Insulation in Westerleigh, NY

Spray foam insulation in Westerleigh deals with a neighborhood that sits on high ground. Wikipedia notes that while it is not as high as Todt Hill, some vantage points in Westerleigh look out to Newark and beyond, and its streets are lined with tall trees, some 75 feet or more. Houses on exposed high ground take more wind in winter, which pushes cold air into every gap in the walls and attic.

Where the island's weather is measured

Westerleigh's history began with Prohibition Park, a 25-acre property bought by a temperance group in 1877. Wikipedia notes that the official climate records for Staten Island are compiled at that site today. Those records reflect what we see in houses: humid summers that overheat top floors and cold winters that find every leak. Central Park's 1991-2020 normals show a January mean of 33.7F and a July mean of 77.5F, with average summer dew points near 62F.

Older houses

Many Westerleigh streets still carry names from the Prohibition movement, such as Neal Dow and Clinton B. Fisk. In the older houses we see here, we commonly find have attics with only a thin layer of insulation, open framing bays, and walls with little or nothing in them. Shade from large trees helps in summer, but leaves and debris also mean we check gutters and roof edges for moisture before insulating the attic.

The usual plan

We start in the attic, sealing top plates, chases and the hatch and then adding cellulose to depth. Below, we foam the rim joist with closed-cell. Where walls are empty, we dense-pack them. For finished attic rooms with sloped ceilings, closed-cell foam under the roof deck usually fits better than batts.

Who lives here
