ABOUT ATTIC INSULATION

The most common type of attic insulation is glass fiber. This may be supplied in rolls, or in flat panels known as batts. For ease of handling, and to provide a neater finish, the attic insulation may be supplied with a kraft paper facing. Loose fill fiber glass insulation is also available. This takes the form of small pieces of fiber glass, which can be blown into position. Loos fill insulation is most appropriate for filling in awkwardly shaped and hard to reach spaces, around the corners and edges of the attic. Mineral wool and hemp may also be used as attic insulation.
