Owens Corning's breakthrough binder-free fiberglass insulation is now available with a stapling flange for use in 2x4 and 2x6 stud walls. The new wall products were introduced in August 1998 and became available nationally in the fall. Miraflex was introduced in 1995 and originally available only for attic applications.
Pricing varies widely but is generally higher than for standard fiberglass batts.
Miraflex may not be available from all building supply stores. In fact, EBN found it to be in very short supply when calling several outlets. Owens Corning, long famous for its pink fiberglass, has just introduced a new fiberglass. And it's white. It is produced by fusing two different types of glass together, which results in a curving, twisted fiber that is naturally springy.
