Air moves naturally from warm to cool places. In winter, air will flow from heated places to lower temperature zones in your house, like the attic, basement and eventually escaping to the outdoors. In summer, air moves from warm outdoor spaces to cooled spaces in your home. Chimneys, attics, crawlspaces, floors, walls, and other openings are some of the ways heat can escape or enter your house. A professional Benson Insulation Company will properly insulate your building envelope to help contain heat within your home in winter and keep out heat in summer.
