HUBER TT7 Doors: NYC’s Guardian Against Rising Waters
In a city that never sleeps, resilience is non-negotiable. With the growing threat of storms and rising tides, some of New York City’s most iconic and vital institutions have turned to a single solution: HUBER’s TT7 pressure-rated stainless-steel doors. Designed as a pressure-tight access door, the TT7 is the optimal solution for flood protection, safeguarding lives, infrastructure, and history from nature’s fury.
A Fortress for History on Governors Island
In 2018, one of Governors Island’s historic buildings became an early adopter of the TT7. This 172-acre island, just 800 yards (about 731.52 m) from Manhattan, is home to over 50 historic landmarks and lush parkland. With its proximity to the water, flood protection is not just a precaution - it is a necessity. The HUBER TT7 now ensures that this cherished piece of New York’s history remains safe for generations to come.
Over the years HUBER sold more than ten rectangular Pressure-Tight Doors TT7.1, completely made from high quality AISI 316L stainless steel. The door is statically certified and pressure-tight up to a water gauge of 10 m and opening to the pressure side.
HUBER Technology Inc. is building project specific high resistant flood protection doors that are pressure tight up to a water gauge of 30 m for all types of buildings required protection even considering a guarantee for leakage and tightness between the frame and concrete.
Technically the frames and doors are shielded arc-welded and acid bath cleaned before washing, drying and surface passivation.
Shielding the Hudson’s Architectural Marvels
By 2019, HUBER’s TT7 had earned the trust of real estate giant Tishman Speyer. A TT7 was installed in one of their premier Hudson River properties , reinforcing the flood resilience of their extensive portfolio. With properties spanning NYC, Chicago, and Boston, Tishman Speyer understands the importance of future proofing against extreme weather events
Safeguarding the Future at Barnard College
Fast forward to January 2025, and HUBER delivered yet another TT7, this time to Barnard College – part of the prestigious Columbia University. As an institution dedicated to shaping the minds of tomorrow, Barnard recognizes the importance of proactive infrastructure investments. The TT7 ensures that education and innovation continue uninterrupted, even in the face of climate challenges.
HUBER Technology Inc. equipped the college with different types of four (4x) round pressure-tight doors TT7.R. These doors are even so completely made from AISI 316L, round-shaped instead of typically rectangular. HUBER is building these doors on project with individual diameters and a water tightness up to a water gauge of 10 m.
Expanding Protection to the Heart of NYC’s Future
Most recently, a TT7 was installed in a newly constructed multi-use residential and commercial development. As NYC evolves, so does its need for resilient infrastructure.
From historic landmarks to cutting-edge developments, HUBER’s different types of flood-protecting equipment like the TT7 doors besides other solutions like manhole covers and flood screenings rakes we are proving to be an indispensable safeguard against an uncertain climate future.
