What is insulation?

Insulation is a special type of filling material used in homes and buildings to prevent heat transfer with outside air. Insulation keeps your home warm in the winter and cool in the summer – all while minimizing the workload on your HVAC system. There are several types of insulation available, including:

  • Batts. Pre-cut pieces of insulation that are generally installed between wall studs.
  • Rolls. Pre-cut in width, but come in long lengths to cover areas such as floors and crawl spaces.
  • Blow-in insulation. Loose insulation that can be sprayed into hard-to-reach areas with a specialized air blower.
