Laminated glass retention system

A method of forming a window or door having a glass subassembly with edges surrounded and supported by a frame, the frame and the glass subassembly having an inside surface that faces the inside of a structure when the window or door is installed and an outside surface that faces the outside of a structure when the window or door is installed, the edges of the glass subassembly being seated in a generally L-shaped inside facing channel of the frame with the channel being defined by a peripheral wall and an inside facing attachment surface, the method comprising the steps of:

• applying a retention member to the edges of the glass subassembly, the retention member having a first portion that extends along and engages at least part of the edges of the glass subassembly and a second portion that extends along and engages the inside facing surface of the glass subassembly adjacent the edges of the glass subassembly, the retention member having no portion that engages the outside facing surface of the glass subassembly;
• inserting the glass subassembly with the retention member applied to its edges into the inside facing channel of a window or door frame member so that the first portion of the retention member is disposed along the inside facing wall of the channel;
• seating the edges of the glass subassembly and the first portion of the retention member within a bed of a glazing material applied along the receiving channel;
• and
• covering the second portion of the retention member and a portion of the inside facing surface of the glass subassembly with a stop;
• whereby the retention member holds the glass subassembly within the channel and improves the resistance of the glass subassembly to being dislodged from the channel.
