A method for repairing or upgrading of existing insulated glass units already installed into a window framing or curtain wall system is provided. The method includes removing an inside glass stop from a window framing housing the insulated glass unit to provide access to an inner glass panel and detaching the inner glass panel from an outer glass panel via a breaking or altering of the separator, with the outer glass panel being retained in place within the window framing. The method also includes applying a new separator to the inner glass panel and/or the outer glass panel, reaffixing the inner glass panel to the outer glass panel while maintaining a space between the inner glass panel and the outer glass panel to form a hermetically sealed cavity therebetween, and reinstalling the inside glass stop back onto the window framing, to secure the inner glass panel in place.

A door includes a door frame, first and second door skins having rectangular outer peripheries and inner openings, and a frameless glazed unit received at the openings. The door skins include exterior surfaces facing away from the door frame and opposite interior surfaces facing and secured to opposite sides of the door frame. The exterior and interior surfaces of the first and second door skins establish integral lips and grooves of the first and second door skins Opposite sides of the frameless glazed unit directly contact and are sealed by the integral lips and sealant and/or adhesive contained in the grooves of the first and second door skins.

A window frame insert for an existing window frame can comprise: a window pane comprising a thermoplastic polymer, wherein a length of the window pane is divided into a first portion and a second portion by a living hinge mechanism formed into the window pane that extends across a width of the window pane from one edge to an opposite edge such that the first portion can bend at the living hinge mechanism toward the second portion, and wherein an outer edge of the window pane removably attaches to the existing window frame, and preferably wherein the first portion and the second portion have a haze value of less than or equal to 5% as determined in accordance with ASTM D1003-13, preferably less than or equal to 2%.

A glazing shield system for retrofitting glazing systems of buildings is disclosed. The glazing shield system includes a support frame and a unitized panel. In certain embodiments, the glazing shield system may be mounted on an existing glazing system in a non-intrusive and non-destructive method. In one embodiment, the support frame may be attached to an infill panel of an existing glazing system using structural adhesives, and the unitized panel may be mounted on the support frame, creating an insulating glazing shield.

A wall panel arrangement is designed for use in retrofitting a wall panel system provided with at least one pair of frame members having inwardly facing flat walls for retaining at least one existing glass panel therebetween. The wall panel arrangement includes an add-on glass wall panel and panel mounting structure configured with at least one receiving strip constructed with a planar body having an outer surface secured to one of the inwardly facing flat walls of the frame members in spaced relationship to the existing glass panel. The body also has an inner surface provided at opposite edges thereof with a pair of flexible resilient wall panel retaining elements extending therefrom and converging towards each other to define spaced apart retainer ends which are frictionally engageable with the opposed faces of the glass wall panel adjacent one of the opposed sidewalls thereof.
