New York Luxury Condos with Isokorb®

from Matt Capone

Installation of Isokorb® continues at 199 Mott Street, by Alfa Development.

The 199 Mott St. condo building is being labeled, “The Green Collection” due to the energy efficient initiatives which are being installed in the structure.


Located in the Nolita area of New York, between Kenmare and Spring Street, construction continues to progress on the “steampunk aesthetic” development. Kutnicki Bernstein Architects designed the boutique, eight story building, which will include a ground-level retail area, 11 residential units and a rooftop terrace.

The owners, Alfa Development, are raising the bar on luxury condo construction by implementing design knowledge and well-known strategies to maximize energy efficiency, thermal comfort and indoor air quality.

Alfa began with Chelsea Green by taking responsibility to build to higher energy efficient standards in their luxury condo suites, which sold 90% of their units off the floor plan.

The norm of past developers was to provide sub-standard building quality, with only the faucets, countertops and fixtures upgraded to portray the image of added luxury. Yet the market is demanding more, “Comfort is In,” and upgraded paint, countertops and shiny faucets are no longer enough. To meet today’s demands from the condo market, developers like Alfa are starting with the structure, providing a solid, well build building envelope to provide higher quality, and greater comfort for residents.

199 Mott is quickly following suite with completion of the structural concrete, including Isokorb structural thermal breaks. Here are a few images from our site visits:

Isokorb® structural thermal breaks were installed at the balcony connection, as you can see the placement of the thermal breaks, exposed at the concrete balcony connection point.


The Isokorb® thermal breaks were installed at the continuous insulation (CI) layer to close the gap in the building envelope, and for the building’s insulation to be effective-reducing air leakage. As you can see in the images, the concrete connection, from floor of the concrete balcony/interior slab to the ceiling, and unit above balcony/interior ceiling slab, a continuous layer of insulation has been created (minus the entry doorway to be installed).

This simple step of including Isokorb® structural thermal breaks in the concrete slabs provides energy savings, achieving 90% reduction in thermal conductivity for the connection area.

During our recent site visit, work was progressing on the opaque building envelope.

The opaque envelope from exterior to interior includes brickwork, cavity, continuous exterior insulation (CI) 1″, CMU, steel studs with batt insulation.
