Abstract: Building cladding systems with changeable appearances are described. The building cladding system may include a plurality of panels, a substrate, and a controller configured to move the plurality of panels relative to the substrate to change the appearance of the building cladding system, while protecting the substrate. Moving the plurality of panels to change the appearance of the building cladding system may include rotation.

Abstract: A deck clip that may be used in the construction of a deck and a method of using the same is provided. The deck clip may include a grip and a spacer. Portions of both the grip and the spacer may be received within the grooves of deck boards used in decks. Thus, the deck clip may be selectively affixed to deck boards. Further, the deck clip may be configured to receive a fastener for anchoring the deck clip to joists. Thus, the deck clip may be used to couple deck boards to joists. Advantageously, the deck clip may be used to construct a deck without exposed fasteners, the geometry of the spacer may assist with creating a consistent gap between adjacent deck boards, and the grip may comprise saw-tooth shaped surfaces for improved retention of the deck boards.

Abstract: Provided herein are rafter vents including a ventilated mat extending along a roof structure, the ventilated mat comprising a plurality of entangled filaments, and a backing adhered to the ventilated mat along a surface of the ventilated mat configured to face opposite the roof structure.

Abstract: A floating modular stair system includes a wall mounting plate that is attachable to a vertical wall, and a base mounting plate that is anchorable to a horizontal floor. A monostringer beam is attachable to the wall mounting plate and to the base mounting plate. The monostringer beam includes an integrated hook attachment for variable angle adjustment and attachment to the wall mounting plate. Stair tread brackets are attachable to the monostringer beam for equal spacing of stair treads after installation of the monostringer beam to the wall mounting plate and to the base mounting plate. Each of the stair tread brackets are also designed for individual variable angle adjustment and leveling after attachment to the monostringer beam, and the stair tread brackets are rotatable through an adjustable anchor point about a fixed pivot anchor point to level the stair treads of the floating modular stair system.

Abstract: Polymer composite materials and methods of preparation are discussed. The composite material may comprise a polyurethane foam and a plurality of inorganic particles dispersed in the polyurethane foam. The composite material may have moisture movement properties, such that (a) a sample of the composite material having a length of 48 inches has a moisture movement of less than 0.15% along the length, and/or (b) a sample having a length of 6 inches has a moisture movement of less than 0.8% along the length, when submerged in 45° C. distilled water for 14 days.

Abstract: A radon gas and/or moisture abatement system (or method) is located under the concrete slab of a building. The system (or method) includes a multilayered mat having a first layer, a second layer, and a third layer sandwiched between the first layer and the second layer. The first layer is non-permeable and faces the concrete slab. The third (or sandwiched) layer is an entangled net. The second layer is permeable layer. The layers are bonded together. Whereby radon gas and/or moisture are inhibited from entering the building by passing through and collecting in the multilayer product.
