Why insulation matters in Calgary
In Calgary, the average January low is -12°C, colder than 91% of the 123 cities we track. With winters this cold, the attic is usually the best place to start. Ask the installer to seal air leaks around lights, pipes and the attic hatch before adding insulation, or much of the benefit is lost.
Most rebate programs pay only after an energy assessment, and some need one before the work too. Book it first.
