Insulation is used in building homes and commercial spaces to maintain comfort and protect building material integrity. They are key to building structures, but they are susceptible to damage, like from critters and rodents. Insulation is found in the ceiling of your attic, the attic floor, and in the walls of the structure. Additionally, insulation may be used on fixtures, like extra pipe wrap insulation may be used around water pipes and heating ducts. Insulation must resist heat flow, which is measured with an R-value. The higher the R-value, the higher the resistance, making a more effective insulation.
