Attic Insulation Contractor BloomingtonInsulation is one of the most important components in your home, but one that you cannot see and do not often have the occasion to think much about. The function of insulation is to keep the temperature in your home regulated — keeping the cold air out in the winter and the hot air out in the summer months. So, what exactly is insulation? Well, it’s a term that refers to a substance that slows down the transfer of heat or sound. It can be used in clothing, outdoor gear to keep you warm and in music studios to keep exterior sound out so that recording can capture the best possible sound. Insulation has also been used in homes all over the country for thousands of years.

Earliest Forms of Insulation

In Ancient times, homes would be built with extra thick walls, which would keep the inside of the home cooler and more comfortable, especially in desert climates like Central America and the Sahara Desert. The Ancient Greeks discovered that if they built a cavity wall in their homes, which has a gap between two walls that can capture the hot air, it would keep the interior rooms cooler. The Romans expanded on this theory and used cork and other fabrics to insulate pipes and even curtains. These ancient societies also used asbestos for many years as a form of insulation — it was not until modern times that the negative health impacts of asbestos were really understood. It was not until very recently (mid 1970s) that fiberglass batting began being used. This is what is most commonly used in homes and buildings today.
