A four-storey structurally glazed cube dominates a landmark intersection, creating a stunning atrium space to welcome visitors to the Yonge Eglinton Centre near Midtown in Toronto, Canada.
The cube sits at the foot of a 40-storey-skyscraper and projects above the roof of the centre, providing access to a rooftop. This patio is surrounded by glass walls to provide a safety barrier for visitors without interrupting the views of the city.
At ground level, a glass canopy projects over the entrance doors, supported by a custom designed stainless steel rod structure, giving the impression of an almost free-floating glass ceiling.
Above the roof patio, a second canopy has been installed featuring vertical glazed fins to achieve almost complete transparency.
The towering atrium walls are constructed from individual sections made up of six four metre double-glazed units. Pilkington Optiwhite true low-iron glass was used, and the inside of the outer pane in each features a high performance low-e coating to deliver better thermal insulation by reducing outward radiation of heat.
An argon-filled cavity in the units further increases the thermal insulating properties of the glass, which will help reduce the amount of heating required during Toronto’s cold winters. The units used for the roof of the cube are also extra-clear low-iron glass with a low-e coating and argon cavity, but feature a laminated inner pane to provide greater structural integrity and security to remain in place in the event of any breakage.
The units that make up the cube are supported by a steel beam structure to which they are point-fixed with Pilkington Planar 905 low-profile stainless steel fittings. Additional strength is provided by full-height vertical laminated glass fins.
Phil Savage, commercial contracts sales manager at Pilkington, said: “Pilkington Planar has allowed the architect and wider team to create the defining feature of this project, the large cube made of high-span extra-clear glass units.”
Howard Haber, managing partner at glazing system supplier W&W Glass LLC, added: “The daylight allowed into the building through the energy efficient Pilkington Planar façade is a natural conduit to the new retail, restaurant and public spaces and invites one to enter and explore.”
“The goal with this project was to create a sense of destination and open space for visitors to the centre, and the towering, virtually uninterrupted wall of glass that we, along with our partners at Tagg Industries, built achieves this in a spectacular way.”
The $100m refurbishment of the Yonge Eglinton Centre has created an almost 95,000 sq m mixed-use development, including a high profile retail and dining destination, that will be home to up to 70 retail and hospitality brands.
