Fire protection in One World Trade Center comes from Wabash

Statement issued by Thermafiber:

WABASH, Indiana – Thermafiber’s mineral wool insulation and patented Impasse curtain wall hanger system are being installed in the exterior curtain wall panels of the new One World Trade Center tower in New York City.

Reflecting back on the 10 years since the tragedy of 9/11, Thermafiber employees take solace in knowing that their products will protect and insulate the new One World Trade Center tower. “The events of 9/11 are something that we will never forget. When we were asked to develop a customized perimeter fire containment system for the building’s exterior skin, we were extremely honored,” says Jim Shriver, Director of Technical Services. “Very early in the design phase of the tower, we worked with the building’s curtain wall supplier to develop a system to fit the building’s unique design while providing the necessary thermal insulation and fire rating.”

For decades, Thermafiber has been an industry leader in creating passive fire containment systems for high rise buildings. The One World Trade Center tower will have 104 stories with an overall height of 1776 feet. Currently the steel framework for the tower is constructed up to the 80th floor. When completed in 2013 it will be the tallest building in North America. Thermafiber has been actively involved in multiple projects on the World Trade Center site. Thermafiber also provided insulation and customized fire containment designs for the new World Trade Center Tower 4 and Tower 7.

Thermafiber mineral wool insulation offers products with recycled content up to 90%, in addition to contributing to 33 LEED credits across four categories. Mineral wool insulation is made by melting blast furnace slag, a byproduct of the steel industry, and a blend of natural rocks. The slag and rocks are melted in a furnace at temperatures exceeding 2600° F and then spun into fibers used to form insulation batts and boards. Mineral wool is commonly used in commercial buildings because of its fire resistance and insulating properties. Mineral wool insulation can withstand temperatures over 2000° F for over 5 hours. Thermafiber’s insulation will contribute to the energy efficiency of the building envelope and the anticipated LEED Gold certification of the One World Trade Center tower.
