High-profile wildfires doing substantial property damage to urban areas in B.C. and Alberta have spurred NRCan to look at creating Canadian building standards for wildfire resistance. The consultation process has just begun, but it seems likely that some day soon we may see new codes requiring resistant windows, doors and other components in wildfire-prone areas. What might these rules look like? How do we determine if a product is sufficiently resistant to external fires? And what is the science behind making frames and glass that resists fire and prevents heat transfer to the home interior? Robin Urquhart has worked on rebuilding communities destroyed by wildfires and joins the Conversation to share his deep knowledge of this topic.
