Each material that is used to make up your house has an insulating value, the effectiveness of these materials varies widely. For example, a one inch thick blanket of fiberglass insulation, has the same insulation value as approximately a 22-inch thick wall of common brick, or a 4½ feet layer of stone. The types of insulation used in modern homes that are the most popular are blankets and batts of fiberglass, and rock-wool, fiberglass board, rigid foam boards etc.
Fiberglass and rock-wool blankets and batts
Approximately 90% of all home insulation is fiberglass and rock-wool blankets and batts. They are made of fibers that are compressed in a roll form like a blanket or in short rolls (batts). Blankets and batts come in many thicknesses and widths, and with or without vapor barrier material on one side. Another form fiberglass and rock wool have is shredded, or blown by machine to its place. When these materials come into direct contact with your skin they can cause irritation. Even though loose insulation (blown by machine) is cheaper to purchase and install, it will lose some of its insulating value. Fiberglass and rock wool insulation have excellent insulation values and are among the most economical types to purchase.
Rigid boards
Rigid foam is used for basement walls, exterior walls, concrete slabs etc. rigid boards are manufactured in a variety of materials such as, polystyrene rigid boards, fiberglass boards, and rigid foam boards.
Loose insulation can be blown into walls and other areas, the most popular efficient and inexpensive loose insulation is the fiberglass and rock wool.
