Appeal No. 95-3935
Application 08/162,995
THE INVENTION
Appellants claim a premanufactured, flexible composite sheathing material
comprised of a layer of flexible reinforcing material having a coating thereon, wherein the
coating includes a flexible matrix comprised of recited amounts of an aggregate, filler and
binder, and wherein the binder is sufficiently flexible that the matrix will not crack or crumble
when the sheathing material is rolled or folded. Appellants state that the sheathing
material can be premanufactured to provide a broad range of aesthetic finishes such as
simulated stucco, stone or brick-like finishes (specification, page 2, lines 19-21). Claim 1
is illustrative and reads as follows:
1. A pre-manufactured, flexible, composite sheathing material comprising:
a layer of flexible reinforcing material, said reinforcing layer having an inner surface
and a support surface, and
a performance coating applied to the support surface of the reinforcing layer, said
performance coating defining an exposed surface and including a flexible matrix
comprising a mixture of from about 10% to about 70% of an aggregate, from about 5% to
about 80% of a filler and from about 5% to about 30% of a binder, said binder being
sufficiently flexible to allow rolling and folding of the sheathing material without cracking or
crumbling of the matrix.
