Glass Talk Episode #59: No Gain, No Pain – Geoff Shellard, Guardian Glass

It’s happened – a Canadian jurisdiction has mandated a maximum allowable temperature inside a dwelling space. The Vancouver rule is related to health and safety rather than energy efficiency, but it seems likely that requirements for cooling homes will soon put pressure on fenestration designers to restrict solar heat gain in addition to insulating against heat loss. Is the market reacting? How will this change our designs? Guardian’s Pacific Northwest ADM, Geoff Shellard, returns to Glass Talk to shed some light on the topic.
