The main seal, generally made from silicone or polyurethane, bonds the glass system to the frame and avoids wetness from going into the area in between panes. When this seal stops working, the insulating gas (typically argon or krypton in energy-efficient windows) leaves, and outside air infiltrates the cavity.
