  • Patent number: 11505951
    Abstract: A deck system including hold-down devices for attaching deck boards to deck support structures and a siding system including attachment devices for mounting siding boards to wall structures. Hold-down devices are attached to deck support structures by horizontally-extending fasteners and attach the deck boards to the deck support structures without fasteners providing paths for water to pass through the deck boards into the support structures. Deck board engagement members of the hold-down device extend into slots in deck boards. Siding board attachment devices are mounted on upright surfaces of wall structures using horizontally extending fasteners. Siding boards are mounted with a standoff distance providing ventilation space behind and between siding boards.

  • Patent number: 9109368
    Abstract: 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.
