Building Envelope Solutions
Spray foam in the Bronx
The Bronx has every kind of building we spray: one- to three-family houses in Throgs Neck and Pelham Bay, row houses in Morris Park, pre-war apartment buildings along the Grand Concourse, and warehouses in the South Bronx.
Where we spray
- Houses: under the roof deck, on rim joists and in basements.
- Apartment buildings: roof decks and bulkheads, where most of the heat leaves a pre-war building.
- Warehouses and industrial space: closed-cell foam on roofs and walls, which also stops condensation. See commercial insulation.
- Houses near the water: in Throgs Neck, City Island and Edgewater Park, closed-cell foam where damp air is a concern.
Open cell or closed cell?
- Closed cell: for roofs, rim joists, basements, masonry and anywhere moisture matters.
- Open cell: lighter, for pitched roofs and framed walls, and it helps with noise.
Incentives
The Bronx has Con Edison gas and electric. Buildings with 5 or more units may qualify for the Con Edison multifamily program, and one- to four-family homes may qualify for NYSERDA programs. We check what is open before we price the job.
Common questions
Is spray foam or blown-in better for brick buildings? For closed brick walls, blown-in is usually simpler. For roofs and basements, foam seals and insulates in one step.
Can you work in an occupied building? Yes. We isolate and ventilate the work area and plan the job with the building.
