Fiberglass Batt Insulation
The most widely used product for wall insulation in North America is Fiberglass Batt Insulation. This is due to the inexpensive nature of the product. Fiberglass or Roxul Batts provides basic insulation by trapping air molecules in the fibers. The plastic (poly) vapor barrier is used to prevent that cold air from entering your home.
