A building sub-floor construction comprising a plurality of elongated beams formed of rigid polymer foam material, wherein the elongated beams comprise similar cross-sectional shapes, and wherein the elongated beams are configured to snuggly engage one another along their lengths to produce a continuous slab.

A moisture barrier system, comprising a barrier sheet adapted to be installed on a building having an interior wall structure and an exterior wall structure spaced apart from the interior wall structure to define a cavity there between.

There is provided a ventilating sill plate for elevating a wall portion from a receiving surface. The ventilating sill plate comprises at least one longitudinal base having a first and a second face opposite the first face extending along a longitudinal axis, the first and the second face extending laterally perpendicular to the longitudinal axis between a first and a second lateral side. A plurality of longitudinally spaced support legs extend away from the second face and define at least one ventilating channel extending from the first to the second lateral side of the at least one longitudinal base. A plurality of support pads project from the first face and collaborate for supporting the wall portion. A plurality of longitudinally spaced arms are shaped and sized to receive the wall portion therebetween.

Aspects of the disclosure relate to a drain assembly that incudes first and second plates, moisture inlet and outlet, a flexible sheet disposed between the first and second plates and extending between the moisture inlet and outlet. The flexible sheet is configured to wick moisture. The drain assembly is configured to position in an opening in a building envelope assembly, seal between the moisture inlet and the moisture outlet adjacent the flexible sheet, and transport moisture from the moisture inlet to the moisture outlet to transport moisture from an interior side of an envelope penetrating component positioned within the opening to an exterior side of a water separation plane.

A through-wall flashing support system for supporting a through-wall flashing membrane installed in a cavity wall. The system includes multiple support parts, multiple spline parts and a through-wall flashing membrane. Each support part has a flange, configured to abut and be attached to an inner wall of the cavity wall, and a base, extending with a downward slope from the lower portion of the flange such that the outer portion of the base penetrates an outer wall of cavity wall. Spline parts are configured to connect adjacent support parts. The through-wall flashing membrane extends across the cavity and covers the bases of the support parts and the spline parts. Weep holes are installed to enable water to flow through the outer wall along through-wall flashing membrane. Methods for installing this system in a new cavity wall and retrofitting an existing cavity wall are also provided.

An elongate connector for connecting a first building panel and second building panel, the connector comprising: a hollow and elongate recess defined by two spaced apart side walls separated by a top wall, the recess being arranged to receive a load bearing member positioned above the first building panel and wherein the top wall and side walls are arranged to be received into a channel of the second building panel thereby positioning and inter-connecting the second building panel above the first building panel; a flashing portion extending along the length of one of the side walls, said flashing portion depending downwardly from one of said side walls to lap over an edge portion of said one of the building panels.

There is provided a ventilating sill plate for elevating a wall portion from a receiving surface. The ventilating sill plate comprises at least one longitudinal base having a first and a second face opposite the first face extending along a longitudinal axis, the first and the second face extending laterally perpendicular to the longitudinal axis between a first and a second lateral side. A plurality of longitudinally spaced support legs extend away from the second face and define at least one ventilating channel extending from the first to the second lateral side of the at least one longitudinal base. A plurality of support pads project from the first face and collaborate for supporting the wall portion. A plurality of longitudinally spaced arms are shaped and sized to receive the wall portion therebetween.

An end cap for preventing ingress of moisture to the end face of a structural beam, wherein said structural beam comprises metal, stone, concrete, reinforced concrete, or a mixture thereof; said end cap comprising: (i) an end plate having a shape matching the transverse cross-section of said structural beam; and (ii) a skirt for holding said end plate in position; wherein said end plate and said skirt comprise or consist of a material for preventing transmission of moisture.

There is disclosed a system and method for wall panel trim installation. In an embodiment, the system comprises a plurality of horizontal and vertical trim profiles having a back plate adapted to receive a top cap within a bracket, the bracket including a mounting base and walls extending up from either side of the base; and at least one flange formed on the walls and extending outwardly, the at least one flange including a shallow channel; wherein, upon receiving the top cap within the bracket, the at least one flange forming the shallow channel and a portion of the top cap secure an edge of a wall panel therebetween. In an embodiment, the shallow channel formed within the at least one flange is adapted to receive an adhesive or sealant. The top cap is partially received within the bracket such that a clearance is formed between a bottom of the mounting base and a bottom of the top cap. Back plate and top cap pairs allow installation of wall panels placed into position without fasteners.

A wall panel is provided that can be prefabricated and pre-assembled, and can be easily and quickly installed in the field. The wall panel includes an exterior infill component, an interior structural component, and a frame. The frame includes a first jamb member, a second jamb member, a head member, and a sill member. A wall system is provided comprising a plurality of wall panels. A method of installing the wall panel system and a method of assembling the wall panel are also provided.
