Rain screen siding system

摘要

A rain-screen siding system for buildings, including clips to support siding boards parallel with a flat surface of a building wall structure but spaced apart from the building wall to allow air to circulate between the building wall structure and the siding boards. The clips include paired, opposed channels and the siding boards have tongues that fit into the channels. Drainage grooves are defined in the clips. Bottom support members may extend horizontally to support the siding boards at the bottom of the rain screen siding. Corner closing members are provided to protect end faces of siding boards at an exterior corner of a building wall.

主权项

1. A rain screen siding system, comprising:
(a) a plurality of mounting clips of unitary construction; (b) a plurality of siding boards supported on the mounting clips, wherein each siding board has a width and includes:
(i) an inner face;(ii) an outer face;(iii) a first tongue extending along the siding board adjacent a first margin of the board;(iv) a parallel, oppositely directed second tongue extending along the siding board adjacent a second margin of the board, the first and second tongues respectively defining opposite longitudinally extending margins of the inner face;(v) a skirt portion including a marginal portion of the outer face located along the second margin of the siding board and spaced outwardly apart from and extending beyond a margin of the second tongue; (c) and wherein each of the mounting clips includes:
(i) a planar mounting base having an outer face;(ii) a standoff structure attached to the mounting base and extending outwardly therefrom;(iii) a first pair of inner and outer channel wall members defining a first, upwardly-open, channel;(iv) a second pair of inner and outer channel wall members defining a second, oppositely directed, downwardly-open channel; and(v) the standoff structure including an upper support member extending downward obliquely from the outer face of the mounting base and a lower support member extending generally horizontally from a lower margin of the mounting base to the inner channel wall of the second, downwardly-open channel, said standoff support structure interconnecting the channel wall members with the mounting base, and said inner channel wall members being parallel with and spaced apart from the mounting base: and wherein d) a first tongue of a first one of the plurality of siding boards is engaged in the second, downwardly-open channel, and a second tongue of a second one of the plurality of siding boards is engaged in the first, upwardly-open, channel, with the skirt portion of the second one of the plurality of siding boards extending alongside and being spaced outwardly apart from the first tongue of the siding board engaged in the second, downwardly-open, channel, and the tongues of the first and second ones of the plurality of siding boards thus engaged in the mounting clip being spaced apart from one another and defining an open passageway between the adjacent first and second ones of the plurality of siding boards, through which an unobstructed flow of air is possible to ventilate an air space adjacent said inner face of each of said plurality of siding boards.
