Reflective insulation is the most effective when airspace exists between the insulation and the adjacent material. The R value of the system will vary dependent on the airspace size and the direction of the heat flow, and the conductive and convective properties of surrounding materials.

When installed in commercial structures such as metal buildings Foil-Fiberglass-Vinyl (FfgV) Commercial Insulation can increase comfort and reduce energy costs. In the southern states where typically 3" or 4" faced fiberglass is used to insulate, FfgV Commercial Insulation is an ideal choice. The compact, lightweight rolls are easy to handle during installation and the finished appearance is excellent. Because the core of FfgV Commercial Insulation is 1/4" high-performance fiberglass and is bonded to a durable reinforced facing, you get a smoother, cleaner interior appearance.

FfgV Commercial Insulation will keep the building space comfortable during the warm summer months and provides a clean interior appearance.

FfgV Commercial Insulation is easy to work with in both new construction and in retrofit applications. Because FfgV Commercial Insulation is so thin, it is easy to handle. Splices are quickly and easily made, so you can buy FfgV Commercial Insulation in standard (4 ft. wide) roll sizes, eliminating the aggravation of ordering your insulation in custom cut roll lengths and the necessity of sorting your rolls at the jobsite to determine which rolls fit where. For retrofit applications FfgV Commercial Insulation compact roll size make it simple to install from below.

Residential Applications

Our commercial grade Foil-Fiberglass-Vinyl Commercial Insulation is an ideal product for use in a multitude of residential applications. It is ideally suited to be used in attic applications below the roof deck in both new construction and retrofit. FfgV Commercial Insulation will reduce heat gain in the attic area on a hot summer day thereby reducing the temperature differential between the attic area and the occupied space below. The lower temperature differential will reduce the cooling load and will help keep the occupied space more comfortable. 

FfgV Commercial Insulation can also be used in sidewalls, crawl spaces, cathedral ceilings, below floors, metal buildings, pole barns and more.
