New York City code requires new additions to meet current fire codes, even if the existing structure does not. For this Brooklyn brownstone renovation, that meant the addition to the rear of the building had to be made of noncombustible reinforced masonry block. But insulating the new block structure to Passive House EnerPHit levels was a challenge. The solution was to wrap the masonry in an exterior insulated finish system (EIFS) — including the rooftop parapet. Watch as Jose Maldonado's crew attaches the foam insulation to the concrete cap of the block parapet wall.
