Abstract: A laminated single is provided, having lighter and darker granule portions visible from the front, at different planes; the front-most or anterior plane generally having granules of lighter shading and the more rearward or posterior plane generally having darker granules. The darker granules in the more posterior plane are visible from the front of the shingle to provide visually sharp, precise delineation between zones of lighter and darker shading. The shingles may be of multi-layer construction with suitable adhesives securing the layers together. The darker granules may be visible from beneath the lower edge(s) of the anterior shingle, to provide a shadow line effect. Alternatively, or in addition thereto, the darker shingle zones from the more posterior plane may be visible through tab-separating slots of the lighter shaded anterior shingle portion.

Abstract: Exterior finishing panels are provided which contain an elongated, thermoplastic sheet which is supported by a rigid support member disposed along a portion of the length of the sheet. The rigid support member has a flexural modulus which is significantly greater than the modulus of the thermoplastic sheet, so as to support the panel during handling and installation. The panels of this invention will be more kink-resistant, and will ride uneven walls better to present a flatter-looking finished wall surface. These panels are also capable of being worked with ordinary hand tools, such as a standard wood saw made of steel or carbide.
