N.C.F.R. Homasote®
N.C.F.R. Homasote® is a structural building board and substrate for interior or exterior application, offering constant insulation against air, moisture and noise penetration. It is a UL fire-rated structural building board and UL recognized component in floor protectors and wall shields. Fire Rated N.C.F.R. Homasote is made with 55% recycled, all cellulose fiber material completely impregnated with fire retardant chemical ingredients, treated for protection against termites, rot, fungus, and moisture absorption, and compressed into high-density, structural exterior building board. Made with FSC® certified material.
N.C.F.R. Homasote qualifies for use in educational, institutional, museum, or any publicly-attended facilities. It is ideal as a tackable wall and ceiling paneling, decorative or functional display wall and tack board, or tackable substrate for other fire-rated wall coverings. It can be used as a structural component (such as wall sheathing), or as noise-deadening, resilient carpeting underlayment. It is used anywhere flame rating is a factor:
- In residential, mobile and commercial buildings
- In fire rated garage interiors
- In marina interiors and exteriors
- As interior or exterior siding for horse barns and other animal shelters
- As a floor surface protector in commercial renovations
