Abstract: This application relates to I-joists which are configured to resist fire damage. Specifically, the present application relates to reinforcing I-joists with reinforcing members configured to provide structural support and/or to provide a physical barrier to fire. This may help the I-joists to maintain structural integrity during a fire and so help improve safety during evacuation of a building and during fire-fighting operations.

Abstract: This application relates to compositions and methods for coating timber and the like to increase the fire resistant properties of the timber. Specifically, the compositions include water, acrylic resin, aluminum trihydrate and ammonium polyphosphate that can be used to effectively coat lumber products and impart fire-resistant properties to the lumber products. In addition, the compositions can include an anti-microbial agent to increase the anti-microbial properties of the coated timber products. The compositions can also include a coloring agent in order that coated lumber products have a recognizable tint indicating to users that the lumber products have been treated with the compositions to increase the fire-resistance and anti-microbial properties of the lumber.

Abstract: An exterior building cladding system and methods of applying the building cladding system are described. The system is a weather resistive barrier and decorative system that is particularly effective as a covering system for buildings having an exterior wood substrate. The system includes a flexible waterproof base layer of acrylic and rubber that is adhered directly to a wood substrate, a mesh embedded in the flexible waterproof base layer and an acrylic stucco outer layer adhering directly to the flexible waterproof base layer. The system eliminates the need for building wrap while providing a moisture resistant and vapour permeable layer.

Abstract: An insulated wall assembly which combines strength with good insulating qualities includes spaced apart, elongated wooden posts, which are I-shaped in cross section; and elongated rigid foam plastic panels extending between adjacent posts, the panels being generally cruciform in cross section so that projections on the lateral edges thereof extend into the recesses of the posts while the front and rear or outer and inner surfaces of the panels are in the same planes as the outer and inner surfaces of the posts. Alternatively, the panels are parallelepipedic blocks with longitudinally extending, rectangular grooves in the sides thereof for receiving splines, which connect the blocks to rectangular, grooved insulating inserts in the posts.
