Insulation
Question: How does Insulation work?
Answer: Insulation acts much like a jacket. Just as a jacket serves to keep heat in your body heat and provide a thermal barrier against the outside, insulation does the same with a home’s building envelope. Heat naturally flows from warmer to cooler temperatures. During the winter months, warm indoor air flows toward cooler unheated spaces (such as a garage or attic). In the summer months, the unheated outdoor air flows toward a home’s cooled interior. Whenever there is a temperature difference you will find heat flow. Insulation works by decreasing the heat flow and creating a barrier between or resistance to the heat flow.
