Large-scale structural glazing facades characterise the Manhattan district of New York, where commercial properties are increasingly being used for residential purposes. Now a special project has been realised there: In Hudson Square, a glazed tower directly above a historic building creates new living space. In the insulating glass, the highly efficient Warm Edge from the manufacturer H.B. Fuller | Kömmerling ensures low energy costs and a pleasant living climate.
At 102 Charlton Street, in Hudson Square on the south side of the block between Greenwich and Hudson Streets, the New York real estate company Lalezarian Properties completed a new project in the winter of 2021/22. A modern residential building with 22 floors was placed over a five-storey existing building. Thanks to its special construction, the new building cleverly closes a narrow gap between buildings, blends in visually with the surrounding high-rise buildings and at the same time leaves the historic substance of the old building untouched, including the ornate facade.
Historical and modern architecture combined
Ismael Leyva Architects, New York, are responsible for the design. Among other things, the medium-sized architectural firm realises numerous projects in residential construction as well as in the renovation and redesign of historic and listed buildings.
With the exception of the western facade, the 64-metre-high building on Hudson Square is glazed throughout. Similar to a stacked storey, the upper third of the tower jumps back over a bevelled line and opens up a characteristic silhouette when seen from the street. The new building has a total of 61 residential units. The large glazed areas allow plenty of natural daylight into the rooms and offer an unobstructed view of lively Manhattan.

Elastic edge seal for high energy efficiency
In order to achieve maximum energy efficiency in the building and to make optimum use of the air-conditioning in the flats, the glazing of the facade is fitted with the Ködispace 4SG warm-edge system from the adhesives and sealants manufacturer H.B. Fuller | Kömmerling. The reactive thermoplastic spacer for insulating glass offers the highest energy efficiency and maximum service life, combined with a unique appearance.
Insulating glass with Ködispace 4SG has proven to be exceptionally robust, resilient and durable, because the chemical and at the same time elastic bond between sealant and glass creates a tight and at the same time extremely flexible edge seal.

In this way, the thermoplastic spacer not only compensates for the temperature differences between summer and winter that are common on the American East Coast, but also reliably keeps out moisture and wind.
The functionality of the glass remains permanently intact. This not only creates a feel-good atmosphere in the new flats, but also saves the residents heating and air-conditioning costs in the long term.
For the new building, the glass elements were manufactured by Oldcastle BuildingEnvelope at its plant in Perrysburg, Ohio. Together with the Warm Edge from H.B. Fuller | Kömmerling, they make a decisive contribution to a pleasant indoor climate, high-quality design and economical energy consumption in the new New York residential building at 102 Charlton Street.
