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 98% recycled,
all wood 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
