Underwriters Laboratories (UL) Canada opened the doors of its new building envelope test lab in Toronto, to members of the construction industry with a ribbon-cutting ceremony and open house. The new lab has been operational since November 2018.

Accurate assessment of the watertightness of new and existing roofs can potentially save building owners hundreds of millions of dollars annually. The challenge for roofing specifiers is choosing the most effective exterior-to-interior watertightness evaluation techniques because there is no single, straightforward method to accurately assess water ingress. It is, however, possible to obtain reliable information on the watertightness resistance and condition of an existing roof system by combining water-detection methods.

As one of the world’s most versatile building materials, with a wide range of esthetic options and outstanding energy characteristics, glass provides numerous opportunities to enhance buildings’ visual appeal and performance.

What could be more fundamental than the air we breathe? As it is invisible and a part of everyday life, people can sometimes take the quality of air for granted. Indoor air in Canadian buildings may contain hundreds of volatile organic compounds (VOCs)—a diverse group of chemicals emitted as a gas at room temperature that often reach higher concentrations than outdoors.

Design/construction professionals can minimize their difficulties with onsite, or ‘in-situ,’ testing of fenestration components by adhering to certain well-established quality control (QC) principles that can reduce the chances of costly failures. However, there is little doubt onsite testing can be a complex undertaking.

The use of natural stone on buildings and paving can be traced back to the beginning of civilization. There are countless buildings, monuments, and structures dating back thousands of years that have stood the test of time and left generations in awe.

Useful standards for testing the physical performance of windows have been developed over many years, culminating in the North American Fenestration Standard (NAFS). This standard was first published in 2005, with new editions available in 2008 and 2011.

Adoption of the North American Fenestration Standard (NAFS) has resulted in big changes in the fenestration industry. However, does this signal changes for exterior wall materials, as well? Extruded aluminum—aluminum alloy which has been pressed through a die to create building components with unique cross-sectional shapes—is commonly used in curtain wall framing and other fenestration elements.
