Inside the spacer bar lies a desiccant (a drying representative) designed to soak up any recurring moisture trapped throughout production.

Over time, due to age, weathering, or bad installation, these perimeter seals can break down. When the seal stops working:

1. Outside air and wetness seep into the cavity between the panes.
2. The desiccant eventually ends up being saturated and can no longer soak up the inbound moisture.
