Abstract: A molded plastic panel for covering an exterior building wall includes a laterally directed lead fin, a laterally extending groove below the lead fin, and a rearwardly directed middle wall between rows of simulated shingles, all for joining laterally adjacent panels. A side flange extending outwardly of the panel may also be included. The molded plastic panel preferably also includes at least one row of simulated shingles separated by a plurality of gaps each having a randomly varying width in order to camouflage spacings between adjacent panels that change because of thermal contraction and expansion. In a particularly preferred embodiment, the panel body includes a locking tab and a folding flange. The folding flange includes a locking lip for engaging a locking tab on an adjacent panel and a flexible hinge connecting the locking lip to the panel body. The flexible hinge allows the folding flange to be disconnected from the locking tab when replacing a single panel.
Abstract translation: 用于覆盖外部建筑物墙壁的模制塑料面板包括横向定向的引线鳍片，在引线鳍片下方的横向延伸的凹槽以及在各排模拟板条之间的向后指向的中间壁，全部用于连接横向相邻的板材。 还可以包括从面板向外延伸的侧凸缘。 模制塑料板优选地还包括由多个间隙分开的至少一排模拟木瓦，每个间隙具有随机变化的宽度，以便伪装由于热收缩和膨胀而改变的相邻板之间的间隔。 在特别优选的实施例中，面板主体包括锁定凸片和折叠凸缘。 折叠凸缘包括用于接合相邻面板上的锁定突舌的锁定唇缘和将锁定唇缘连接到面板主体的柔性铰链。 柔性铰链允许在更换单个面板时将折叠法兰与锁定片断开。

Abstract: An improved shim for use in a siding application includes an elongated sheet of shim stock having a number of elongated indicators thereon to enable the sheet of shim stock to be cut into any of a variety of predetermined sizes for use with a variety of different accessories. In an exemplary depicted embodiment, the sheet of shim stock also includes an elongated V-groove disposed generally centrally thereon. The V-groove enables the sheet of shim stock to be deflected between a substantially planar configuration and an angled configuration. The indicators provide detectable guides along which the sheet of shim stock can be disunited to remove desired excess portions of the sheet of shim stock in order to provide a resultant shim having a transverse size that is suited for use in conjunction with a particularly accessory.

Abstract: An improved siding panel has a fastening hem that includes an engagement member structured to extend outwardly from a building when the siding panel is mounted to the building. The engagement member is generally trapezoid-shaped in cross section and includes a first leg, a second leg, and an apex portion disposed therebetween, with spaced elongated openings being formed in the apex portion. The siding panel is cooperable with a fastener having an elongated shank and a head to mount the siding panel to the building. The siding panel is mounted to the building by receiving the shank through one of the openings. During certain wind loading, the apex portion is engageable with the head, which thereby deflects the first and second legs from a relaxed position to a deflected position where the edges of the opening can engage the shank of the fastener to provide a greater resistance to wind loading.
