Abstract: A profiled insulating underboard for insulating and aligning metal or plastic siding panels is disclosed. The underboard is formed from a suitable insulating material into a sheet having one substantially flat planar surface and an opposed surface with a configuration or profile which corresponds to the inner contour or profile of the siding panel so that it will fit snugly against the inner surface of the siding when installed. Each sheet of underboard, which is received against the exterior wall surface of a building, has a series of integral projections spaced along one longitudinal edge surface so that adjacent sheets are automatically spaced from each other to permit ventilation and help prevent moisture build up once the underboard and the siding have been fixed to the exterior surface of the building.

Abstract: A simulated cedar shake panel for walls or roofs having at least two courses of simulated shakes in relief therein, the shakes being in overlapped and underlapped relation with a varied butt line, and recessed underlaps between side-by-side shakes. Part of each underlap is recessed enough to contact the roof or wall surface and provide a multiplicity of support surfaces for the panel. A step provided in each underlap near the bottom thereof forms part of the shake simulation and also adds to the structural rigidity of the panel.Tongue and groove side-to-side and top-to-bottom panel interlocks form part of the shake array simulation, so that the interlock structure is concealed and the desired non-uniform shake appearance enhanced.A stackable corner member one shake high is provided, the corner member having a skirt element which interfits with the butt edges of overlapped panel shakes to take up gaps due to the random butt line.An angled cap member is provided to finish off hips and ridges.

Abstract: An angled cap member is provided to finish off hips and ridges for use with a simulated cedar shake panel for walls or roofs having at least two courses of simulated shakes in relief therein, the shakes being in overlapped and underlapped relation with a varied butt line, and recessed underlaps between side-by-side shakes.
