Home Energy Efficiency and Insulation in Canada
Reference material on heat loss prevention, insulation standards, window sealing, and practical approaches to reducing heating costs across Canadian climate zones.
Recent Topics
How climate zones determine minimum insulation depth, what distinguishes cellulose from fibreglass and spray foam, and where most installations fall short of the rated R-value.
Three mechanisms through which windows lose heat, practical low-tech methods for locating infiltration points, and a comparison of sealing products for Canadian winter conditions.
Why the order of energy upgrades matters, which improvements deliver the highest return per dollar in cold Canadian climates, and what federal and provincial programs currently apply.
About This Archive
Daily Oakridge documents home energy performance topics relevant to Canadian residential buildings. Content covers insulation materials and R-value requirements across the eight climate zones, window and door sealing methods, heat loss diagnostics, and the sequence in which upgrades tend to produce the best measurable results.
Material draws from publicly available standards, Natural Resources Canada guidance, provincial building codes, and building science literature. Articles are updated when referenced standards or programs change.
