Abstract
A building composite panel including at least one longitudinal edge is made of a core of hydraulic cement and a multi-ply edge facing material covering and attached to at least one of the longitudinal edges. The facing material includes at least a first ply configured for attachment to the core as it sets and at least a second, water-impermeable ply.
Claims17
A building composite panel including at least one longitudinal edge face, comprising:
- a core of hydraulic material having a top major face and a bottom major face, each major face adjoining the longitudinal edge face;
- a slurry-permeable reinforcing material attached to one or more of said major faces;
- and,
- a multi-ply edge facing material, that is different from said reinforcing material, covering and attached without adhesives to said at least one longitudinal edge face and attached to only a portion of each of said major faces, said edge facing material overlapping said reinforcing material and said top major face and said bottom major face, and comprising at least a slurry-permeable first ply embedded in said longitudinal edge face and a second, slurry-impermeable ply bonded to said first ply, wherein between about 10% and about 50% of the width of the edge facing overlaps with the first reinforcing material.
