UOHI turned to new duct sealing technology to solve one problem and wound up solving two. Hospital monitors detected that an isotope created in one of the institute’s laboratories had somehow migrated to an adjacent wing of the building. By using Aeroseal technology to seal possible leaks in one of the ventilation shafts, the hospital could ensure that the isotope wasn’t spreading from one shaft to the other. Once the shaft was Aerosealed, the hospital immediately noticed another significant benefit – dramatically improved ventilation efficiency and lower energy costs.
