Exactly what is a Misted Glass Unit?

To comprehend the issue, it assists to comprehend how double glazing works. A basic double-glazed window-- technically called an Insulated Glass Unit (IGU)-- includes two panes of glass separated by a spacer bar. The space between the panes is normally filled with an inert gas like argon and sealed firmly around the edges with a primary and secondary sealant. Inside the spacer bar lies a desiccant (a drying representative) created to soak up any recurring moisture trapped during production.

Gradually, due to age, weathering, or bad installation, these boundary seals can break down. When the seal fails:

1. Outside air and wetness leak into the cavity in between the panes.
2. The desiccant ultimately ends up being saturated and can no longer take in the incoming moisture.
