CertainTeed Corp.’s Insulation Group, Valley Forge, Pa., introduces OPTIMA, a fiberglass insulation designed for the Blow-In-Blanket System for use in new construction closed-cavity applications, such as sidewalls, cathedral ceilings and floors. OPTIMA is blown-in without any additives and can be installed using nearly any blowing machine designed for blowing fiberglass insulation. It is permanently noncombustible and contains no chemicals that can cause irritation, corrode pipes and wiring, or create noxious odors. Also, it is not a source of food or nesting support for insects or animals.
