Abstract: A laminated building sheathing comprises a rigid foam board and a facer. The rigid foam board comprises a drainage pattern formed on a major surface of the foam board. The drainage pattern comprises a drainage channel. The facer is configured to cover the major surface of the rigid form board and to essentially conform to the drainage pattern. The facer is semi-permanently bonded to the drainage channel but permanently bonded to non-channel planar portions of the major surface.

Abstract: A laminated building sheathing (20) comprising a rigid foam board (22) and a vapor-permeable film facer (24). The vapor-permeable film facer (24) is adhered to the rigid foam board (22) by an adhesive (26) at non-continuous adhesive locations. The film facer (24) is vapor-permeable, and an extent of non-continuity of the adhesive with respect to area of the rigid foam board is controlled to provide a desired balance between (1) sufficient vapor permeability to conduct vapor to the exterior of the sheathing and (2) a minimum surface area required to effect sufficient adhesion of the film facer to the rigid foam board. In another of its example aspects, a laminated building sheathing comprises a rigid foam board, the rigid foam board comprising a first major surface and a second major surface parallel to the first major surface. The first major surface is configured for being covered by cladding; the second major surface is configured for contact with a building.
