Disclosed herein is a fenestration assembly. The assembly includes a movable sash assembly, a first lock counterpart connected to the movable sash assembly, a fixed sash assembly, a second lock counterpart connected to the fixed sash assembly, and a sill configuration. While the fixed sash assembly is mounted to the sill configuration, and while the movable sash assembly is mounted to the sill configuration at a first height, the movable sash assembly is lockable to the fixed sash assembly. While the fixed sash assembly is mounted to the sill configuration, and while the movable sash assembly is mounted to the sill configuration at a second height, the movable sash assembly is lockable to the fixed sash assembly. While there is an absence of locking between the movable and fixed sash assemblies, the movable sash assembly is movable relative to the sill configuration.

Disclosed herein is a sill configuration of a framework assembly. The sill configuration includes a shoulder, defining a plug supporting surface. The sill configuration is configured for co-operation with the movable sash configuration and the fixed sash configuration so that while a movable sash configuration and a fixed sash configuration are mounted to the sill configuration: (i) the movable sash configuration is slidable, relative to the sill configuration, and (ii) the movable sash configuration, the fixed sash configuration, and the sill configuration are co-operatively disposed so that a space is defined between the movable sash configuration, the fixed sash configuration, and the sill configuration, and (iii) the plug supporting surface of the shoulder is configured for supporting a plug for disposition within the space. While the framework assembly is mounted within the opening of the building construction, the plug-supporting surface is elevated relative to the base.

Various aspects of the disclosure relate to modular sill systems for sliding panel doors and windows, collectively “sliding fenestration units.” In various examples, modular sill systems include multiple separate and distinct base components that provide tracks on which one or more panels are able to slide.

A flashing includes a first edge, a second edge opposite from the first edge, a first surface, and a second surface on an opposite side of the flashing from the first surface. The first surface and the second surface extend between the first edge and the second edge. The first surface includes a hydrophobic region and a hydrophilic region.

An engineered slope sill structure that include a first lateral edge next to the interior side of a building. The structure including a second lateral edge next to the exterior side of a building. The structure also includes a support surface extending from a first portion of the first lateral edge to a second portion of the second lateral edge where the support surface is designed to support a flow control device located in an opening formed by the building. The structure further includes a sloped surface located adjacent to the support surface and extending from a third portion of the first lateral edge to a fourth portion of the second lateral edge where the sloped surface has a first curved slope from the third portion of the first lateral edge to the fourth portion of the second lateral edge to direct moisture to the exterior of the building.

A unified building opening extension system is pre-built offsite. In one embodiment, the extension system is a single sheet of metal cut, bent, and fixed in a predetermined size. The extension system provides an airtight, watertight assembly that is compatible with waterproofing and air barrier systems integrated with the assembly when the opening assembly (e.g. door or window), exterior insulation, and veneer are installed on the building wall. Water intrusion or leaks are resisted even under positive and negative air pressure events (i.e., winds and storms). A sill plate supports an opening assembly in a rough opening of the building and prevents water ingress into the rough opening.

A cladded wall system for constructing cladded cast-in-place concrete walls that are each integrated with lost forms comprising a self-supporting structure made of a plurality of prefabricated cladded panels (PCPs) constituting an exterior lost form, at least one architectural element constituting an interior lost form, and a plurality of concrete integratable connecting units by which each of said PCPs is connected to said interior lost form.

Angled shim stacks and methods of using the same, which can be used to support to a fenestration unit at those locations where the support is needed by providing a load bearing surface that matches the angle of the fenestration unit sill bottom regardless of the angle of the upper surface of the sill on which the fenestration unit is supported.

The present invention is directed towards a window sill flashing comprising a base having a substantially rectangular shape. A front flange projects perpendicularly downward from a front edge of the base and at least one side flange extends vertically from a side edge of the base. The side flange includes a front surface. The window sill flashing is made from a rigid homopolymer vinyl film.

A drip cover for a fenestration unit. The fenestration unit includes a frame and a slideable panel supported for sliding movement within the frame. A gap is defined between the slideable panel and the frame. The drip cover includes a mounting member configured to attach to the slideable panel. The drip cover also includes an overhang that projects from the mounting member and that is configured to cover over the gap when the mounting member is attached to the slideable panel. The overhang is supported for resilient flexure relative to the mounting member between a neutral position and a flexed position. The overhang is resiliently biased toward the neutral position. The overhang, when the mounting member is attached to the slideable panel, is configured to contact a surface, thereby resiliently flexing the overhang between the neutral position and the flexed position, as the slideable panel slides relative to the surface.
