"THE BC YEARS
Thousands of years ago in the BC age, ancient civilizations had their own unique ways of insulating their homes: both Ancient Egpytians and the Vikings took advantage of the cooling properties of mud. Egyptians built their homes out of mud bricks to keep them cool, while Vikings plastered mud and straw in between the logs that made up their homes."

"Ancient Greeks were the first to use a type of insulation that’s still popular today – asbestos. This material was thought to have mystical qualities because it was resistant to flames, so the Greeks named it “asbestos,” which means “inextinguishable.”
