Insulation
Insulation retards heat that moves from warm to cooler surfaces or spaces. In the winter, when warm room air exits through walls, rises up through the attic and roof,

and flows down through the floor, insulation blocks--or at least slows--its departure. And in the summer, when warm outdoor temperatures try to force their way into your air-conditioned rooms, insulation holds the heat at bay.

By slowing heat movement, insulation saves energy and also reduces drafts, making a house more comfortable. Several types of insulation or manufactured, including DIY-friendly batts and rolled “blankets” of fiberglass and rock wool; loose-fill granules, fibers, and cellulose that are poured or blown-in to attics and walls; and various forms of plastic foam.

The effectiveness of every insulation product is measured and rated by an R-value. The higher this value, the better the insulation. For more about R-values, types of insulation, and installation methods, visit the various articles listed below.
