What is Blow-In Insulation?

Blow-in insulation, also known as loose-fill insulation, consists of small particles of fiber, foam, or other materials that are blown into wall cavities, attics, and crawlspaces. This method ensures thorough coverage, filling even the smallest gaps and providing superior thermal performance.
