Although the technology keeps evolving, the concept of insulation is nothing new. For centuries, people have been using specific materials to help achieve a safe, comfortable living space. While today’s homes are wrapped with modern substances like aluminum, fiberglass, and cellulose, older buildings used very different means of regulating temperature. Historical Insulation MaterialsIt may surprise you to learn how people of various periods and cultures have insulated their homes:
- The ancient Egyptians built thick brick homes to keep out cold and heat.
- Many civilizations, such as the Greeks and Romans, have used cavity walls to seal in the hot or cold air and keep it from getting inside. In Alaska, the Eskimos live in thick igloos to provide insulation from the extreme cold.
- Europeans in the Middle Ages built stone structures and covered them with fabric tapestries to keep cold air out and absorb moisture.
- Many cultures, such as Pueblo Indians and Africans, have used mud or clay walls to regulate indoor temperatures.
- Additional insulation materials throughout history have included cotton, straw, wood, sawdust, glass, wool, animal hides, and asbestos.
