Glass and Glazing

Toronto’s CN Tower improves views with floor-to-ceiling dynamic glass windows

The glass darkens in proportion to the sun’s intensity to produce a reduction of heat and glare inside the building.

Recently installed dynamic windows in the CN Tower observation deck include Prel-Shade Thermochromic Glass, from Suntuitive.

The dynamic glass, which was used in floor-to-ceiling windows, is sun-responsive and gradually darkens as the sun heats it. The glass darkens in proportion to the sun’s intensity to produce a reduction of heat and glare inside the building. As the sun’s intensity wanes, the glass transitions back to a clear state.

The glass allows the CN Tower observation deck to remain comfortable and offer clean views regardless of weather, temperature, or time of day.

For glass openings, how big is too big?

Advances in glazing materials and glass building systems offer a seemingly unlimited horizon for not only glass performance, but also for the size and extent of these light, transparent forms. Both for enclosures and for indoor environments, novel products and assemblies allow for more glass and less opaque structure—often in places that previously limited their use.

Mastering the higher ed campus building envelope

Building envelope choices for campus, cultural, and infrastructure projects are shaped by particular conditions. Today, institutions place greater value on how buildings relate to their ensemble: how historic buildings fit next to new ones, how massing forms fit with their neighbors, and how a building cladding contributes to the campus context. Concurrently, enclosure assemblies and construction methods have undergone changes due to values of sustainability, science, durability, and maintenance. In this context, mastering the building envelope on college and university campuses requires addressing both cultural concerns and technical performance, honoring traditional buildings while exploring the potential of new materials and forms.

True Clarity for Ambitious Design

Clear glass is extremely common and is popular for a variety of architectural design applications, including vision glass, spandrel glass, storefronts, entryways and other exterior uses. It is specified repeatedly due to its versatility and ability to serve as a substrate for solar control, low-emissivity (low-E) coatings. However, when specifying glass to achieve a desired aesthetic, design professionals know that clear glass isn’t completely clear.
