A press-fit window insert configured to provide secondary protection to an existing window, having a carrier, a fin, and a fastening clip. The carrier includes a substantially rigid framework having channels within the framework configured to securely accept one or more attachments. The fin extends from the carrier and includes a substantially flexible blade extending from a base portion of the fin. The base portion of the fin is configured to interlock the fin to the carrier. The fastening clip includes a substantially rigid brim extending from a base portion of the fastening clip. The base portion of the fastening clip is configured to interlock the fastening clip to the carrier.

A corner key includes a heel and at least one leg extending from the heel defining a longitudinal axis. A nose is disposed along the longitudinal axis. The nose includes a first wedge area and an opposite second wedge area. The corner key further includes a bridge connecting the nose to the at least one leg. Upon insertion into a frame member, the nose substantially rotates to engage both the first wedge area and the second wedge area within the frame member and wedge the nose therein.

Building systems including a frame with a horizontal member from which first and second vertical bars downwardly extend and a panel attached to the frame. The building systems include at least one of an integrated fastener cover that is moveable to a closed position that covers a portion of a fastener, a gusset assembly with a junction cover positioned at a corner junction between two adjacent portions of a panel, and hinge assemblies that reduce the sagging of a panel, such as a door.

A connector is adapted for securing into a fixed position two frame members that are positioned to define a common miter joint and aligned slots to collectively define a single correspondingly-shaped connector opening. The connector includes a peripheral configuration corresponding to a peripheral configuration of the correspondingly-shaped opening. The connector may have a peripheral surface having on predetermined portions thereof a plurality of stepwise ridges adapted to contact with reduced friction only spaced-apart areas of sidewalls of the correspondingly-shaped opening. The connector may have at least one void in the connector to permit deformation sufficient to accommodate variations between the shape of the connector and the shape of the correspondingly-shaped opening. A method of using the connector is also disclosed.

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 pod 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 corner joint for fenestration frames and the like includes first and second frame members having hollow interiors and ends joined in abutment. A corner key insert has legs inserted into the ends of the frame members. End portions of the legs engage the hollow interiors of the frame members forming adhesive cavities within the frame members and along the end portions of the corner key legs. Adhesive is disposed within the cavities to bond the corner key legs to the frame members, thereby creating a structural joint between the frame members. The corner key insert may include multiple injection ports for delivering adhesive to the cavities from a selected side of the frame assembly. Legs of the corner key may have notches formed therein to receive an internal wall of the frame members, and distal ends of the legs may include a flow barrier that contours along the notches.

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.
