Generated explanation

The illustration shows a divided-light window and the sequence of installing glass, securing it with metal glazing points, and applying glazing putty. The putty forms a beveled exterior seal between the glass and the window muntin. Section A-A compares intact putty with deteriorated putty at the glass-to-muntin joint. In the deteriorated condition, the glass is loose and arrows indicate warm air escaping and water entering through the failed joint.
