OSU William Hall

Aeroseal Helps Ohio State Dormitory Make the Grade

Aeroseal has been featured in the press recently for a project it handled at The Ohio State University (OSU). Construction was complete on the brand new, high-tech, energy-efficient William Hall dormitory, and preparations were underway for it’s grand opening in just a few weeks. Unfortunately, much to their surprise, school administrators were shocked to hear that the new building’s ventilation system FAILED to pass crucial pressure tests needed to meet fire code regulations and targeted LEED requirements.

In Brief

  • Property Owners: Ohio State University
  • Project Contractors: Smoot Construction
  • Property Name: William Hall Complex Expansion
  • Type: 6-story dormitory. 80+ living suites
  • Goal: Eliminate leaks in 19 ventilation shafts; pass fire code specifications; receive LEED Silver certification
  • Results: All shafts sealed in less than two weeks

The building’s ventilation system consisted of 19 individual exhaust shafts, each made up of three layers of fire-rated drywall. Pressure testing revealed that EVERY one of those shafts was leaking.

Traditional sealing methods would have required accessing the entire length of each of the shafts…and that would mean tearing down most, if not all, of the building’s newly constructed walls in order to manually locate and seal each leak. Once sealing was accomplished – the walls would then need to be rebuilt. This was not a tiny problem! It would put the project several weeks behind schedule and add hundreds of thousands of dollars to the budget. Now what?

Enter Aeroseal…luckily an engineer on the project remembered hearing about a new duct sealing technology developed at Lawrence Berkeley National Laboratory that used an aerosol-based approach to seal ductwork from the inside, thereby eliminating demolition to the existing structures.

Articles in the January issue of Green HVACR Magazine and the January 9 online edition of CodeWatcher detail the rest of story about how Aeroseal duct sealing from the inside was able to get this building opened on time and on budget!

About Aeroseal Technology

Before/After Aeroseal
  • Developed at Lawrence Berkeley National Laboratory in 1994.
  • Research for aeroseal technology was partially funded by the U.S. Department of Energy.
  • Aeroseal is the only duct sealant technology that is applied from the inside of the duct system. It is delivered as a non-toxic aerosol mist that seeks out and plugs leaks.
  • Aeroseal has proven to be 95% effective at sealing air duct leaks.
