Boon Edam Inc., a global leader in security entrances and architectural revolving doors, announced that Mt. Sinai Hospital in Toronto has achieved success in reducing wind tunnel issues within its high-volume, three entrance public corridor into the hospital?s main entrance. Dor-Control Craftsmen, Ltd. installed the entrances and oversees on-going maintenance needs. Toronto is known for its cold and blustery winter months. Prior to February 2016, Mt. Sinai Hospital employees, patients, and visitors often had to endure freezing wind tunnel conditions within a street level entrance corridor linking University and Murray Streets. Wind conditions could be so severe that employees using a smaller, employee-designated swinging entrance at times could not manually open that door.
