About Silverstein Properties

Silverstein Properties, Inc. (SPI) is a privately-held, full-service real estate development, investment and management firm based in New York. Founded in 1957 by President and Chairman Larry Silverstein, SPI has developed, owned, and managed more than 35 million square feet of office, residential, hotel, and retail properties in the United States.

The Problem

Silverstein Properties wanted to insulate the front, rear, and rear circle drum of a boiler in its recently acquired property, 3 Mitchell Place in New York City. The 26 story building previously housed the Beekman Tower Hotel. The boiler was running inefficiently and posed a safety hazard because of the high temperature (267°F) of the three components. The boiler must undergo a yearly inspection by an engineer, so ensuring his or her easy access to the boiler was a high priority as well.

The Solution

Rear Component of Boiler Insulated by Removable Thermaxx JacketsThermaxx Jackets provided a solution that improved the efficiency of the boiler by insulating all three components separately with removable insulation jackets, pictured below and to the right. The jackets also lowered the external temper

ature of the boiler, making it safer for employees or engineers who may be working on or around it.

Ensuring easy access to engineers for the boiler's yearly inspection or maintenance work was a unique feature that only Thermaxx Removable Insulation Jackets could provide. The jackets were secured with velcro and D-rings, making their removal and reinstallation simple for employees and engineers alike.

Added benefits include a reduction of greenhouse gases being produced, making the investment in Removable Thermaxx Insulation Jackets an environmentally conscious one.
