Delta MRO Hangar Receives Thermohall® Upgrade

Designed and constructed by Rubb USA in 2000 for United Airlines, the 255ft-span MRO hangar was taken over by Delta Airlines in 2008. The structure remains a key feature of Boston’s Logan International Airport to this day, where it used to maintain Delta’s widebody fleet.

Now it’s received an energy-saving upgrade.

After almost 25 years, Rubb USA has returned to Logan International Airport to recover the MRO hangar with its industry-leading insulated fabric system, Thermohall®. The 2” thick glass wool cladding will keep Delta’s maintenance team warm in the winter and cool in the summer, providing a huge boost to the hangar’s climate control efficiency.

Rubb’s hot-dip galvanized steel framework remained untouched in the process, still standing strong after decades of bitter winters and constant use.

The structure measures 255ft wide x 270ft long with 30ft eaves, providing 68,850sqft of clear-span space for its maintenance, repair, and overhaul operations. With a working environment this large, effective climate control is key—especially in Boston winters, which can drop well below 0°F.

The structure is complete with a main hangar door, featuring an electrically operated Norco system that measures 240ft wide x 50ft high. This not only allows easy access for the aircraft, but works to save energy with its efficient seals.

An iconic fixture at Boston Logan, the hangar has hosted some notable events over the years, including being the drop off location for the New England Patriots’ aircraft after Super Bowl victories and its transformation into a distribution hub for medical supplies during the COVID crisis in 2020.

With nearly 25 years of daily use this hangar still looks and performs as if it was made yesterday. With our modular design and expert engineering, Rubb’s projects stand the test of time.
