A mitre joint for a metallic frame of a fenestration unit includes first and second frame members; a connector configured to locate the first and second frame members in relation to one another; and first and second fasteners configured to secure the first and second frame members to the connector. The connector has a first arm configured to extend within a hollow profile defined by the first frame member, and a second arm configured to extend within a hollow profile defined by the second frame member. A longitudinal axis of each of the first and second fasteners is configured to be parallel to a longitudinal axis of the respective connector arm. Each of the first and second fasteners is configured to engage the respective frame member when the respective connector arm extends within said frame member.

Perimeter frame for sliding glass doors of the type including extruded metal profiles that are combined together circumferentially surrounding the glass sheet having two lateral profiles (1) arranged vertically and that fit on the sides of the glass sheet (4), a set of lower profiles (2) arranged horizontally on each side of the glass sheet (4) at its lower part and a set of upper profiles (3) arranged vertically in the upper area of the sheet glass (4), between which there is provided an opening (5) through which protrudes the upper portion of the glass (6), in which the clamps (7) that hold the sheet are applied.

Embodiments herein relate to fenestrations exhibiting coastal impact performance. In an embodiment, a fenestration unit includes a frame assembly forming a first lower corner and a second lower corner. A first sill corner bracket can fit on a top of a sill and extend from the first lower corner partway along the top of the sill and partway along one side jamb of the frame assembly. A second sill corner bracket can be configured to fit on the top of the sill and extend from the second lower corner partway along the top of the sill and partway along the other side jamb. A bottom sash can include a bottom rail defining a channel to receive at least a portion of the first corner bracket and the second corner bracket therein when the bottom sash is in the closed position. Other embodiments are also included herein.

A corner key for a window assembly may be composed of a first body portion having an inner edge, and a second body portion having an inner edge in which a gap is formed between the inner edges of the first and second body portions. The key may include a channel disposed within the gap and a port in fluid communication with the channel. The first body portion may have a first adhesive bonding area in fluid communication with the channel and the second body portion may have a second adhesive bonding area in fluid communication with the channel. The corner key may be inserted into a first and a second window element. An adhesive material may be inserted through the port to spread through the channel to the first and second adhesive bonding areas inserted into the window elements, thereby forming an adhesive bond therewith.

A frame assembly supporting an overhead door has a horizontal header connected to upright columns or posts with splice assemblies. Fasteners mounted on the columns cooperate with retainers on the splice assemblies to position and connect the columns to the header. Hinge assemblies pivotally mount the door on the header for movement between open and closed positions.

Systems and methods for providing a universal window frame assembly. A window frame assembly can include a plurality of frame members, wherein at least one of the frame members comprises a first profile frame member and at least one of the other frame members comprises a second profile frame member. The at least one first profile frame member and the at least one second profile frame member seat together to form the frame assembly. Head and side jamb members of a window frame can have a common first profile, and a sill jamb member can have a second profile. The frame members can be connected with corner keys configured to engage one or more openings in the first and second profiles. The sill jamb member can provide a sill slope angle.
