Chicago, Ill.
The new 35-story, 807,000-sq.-ft. office building at 151 North Franklin—also known as CNA Center—features two pairs of narrow stile custom balanced doors.
“The project originally called for standard swing doors, but we made the switch to balanced doors because of their functionality,” says Adam Pellar, Vice President, Crown Corr, the glazing contractor responsible for the installation.
SOLUTION:The entrance vestibule consists of revolving doors at each side of the balanced doors creating a cohesive and elegant design. The narrow stile and tempered glass balanced doors have 4.75-in. high top rails, 10-in. high bottom rails, and 1 5⁄32-in. wide stiles, and were factory glazed with 0.75-in. thick low-iron, heat-soaked, tempered glass.
Designed with precision, the Ellison balanced doors and frames are formed and welded using sheet material giving the doors a rigid, unitized structure that withstands the test of time.
151 North Franklin is LEED Gold certified and WiredScore Platinum pre-certified. The building utilizes the latest technology to support connectivity through dependable cellular and Wi-Fi coverage from the basement to the 35th floor.
The Ellison PowerNow-equipped entrances feature Stanley Magic-Force low-energy concealed overhead power operators—complying with the latest ADA Standards and enabling access for all users. PowerNow doors feature an actuating arm for on-demand opening.
