Toronto’s CN Tower Goes Thermochromic

New floor-to-ceiling windows incorporating thermochromic dynamic glass were recently installed on the CN Tower in Toronto.

The building observation deck implemented Canadian fabricator Prelco’s Prel-Shade glass, which uses Pleotint’s Suntuitive interlayer.

Thermochromic glass is sun-responsive and gradually darkens as it becomes heated by direct sunlight. According to Pleotint, the glass will heat up and darken in proportion to the sun’s intensity, resulting in a reduction of heat and glare inside the building during a period of intense sunlight. As the strength of heat from the sun diminishes, the glass transitions back to a clear state.

“We are flattered that the CN Tower incorporated the Suntuitive technology on this iconic landmark,” says Chuck Kuchinick, vice president of North American sales for Pleotint. “This is another fantastic example of how high-performance self-tinting dynamic glazing can be a positive disruption to the building product world, and truly provide a better overall experience for those behind the glass.”
