Cantilever Slabs at Stairways and Shafts

from Matt Capone

Normally cantilevered slabs and edges are considered extensions of the floor or roof levels of a structure. Often times however, conditions require a connection along vertical walls or areas where interiors floors are omitted because of stairways or mechanical shafts. These areas have the same potential problems with thermal bridging since there is an interruption in the continuous insulation layer.

For this Design Break, we explore details of a project in which Isokorb® thermal breaks were used in just such conditions, 15 Leonard Street located in the Tribeca neighborhood of New York City.
