The Inuits of Canada were onto something when they first got into insulating their homes. Icy domes, also known as igloos, enabled the comfort and warmth of up to 16 degrees Celsius - doesn’t sound too warm but putting it perspective, outside temperatures got as cold as -45 degrees Celsius! Tracing back through history, we can see these homes as one of the first shelters that considered insulation. Constructed from whalebone and hides these homes paved the way for modern technology to catapult homes in both colder and warmer regions to provide optimal conditions to live in. Insulation keeps the heat outside during summer, and helps to trap valuable warmth indoors when it’s freezing outside, this lessens the need for any additional heating or cooling.
