Just what is a Misted Glass Unit?
To comprehend the issue, it assists to understand how double glazing works. A standard double-glazed window-- technically understood as an Insulated Glass Unit (IGU)-- consists of 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 agent) designed to take in any recurring wetness caught throughout production.
Gradually, due to age, weathering, or poor installation, these border seals can break down. When the seal fails:
- Outside air and wetness permeate into the cavity between the panes.
- The desiccant eventually becomes saturated and can no longer take in the inbound moisture.
- When temperature level variations happen, this caught moisture condenses on the interior surfaces of the glass.
Since this wetness is trapped inside the sealed unit, no amount of cleaning the inside or beyond the window will make it go away.

This consistent expansion and contraction places tremendous pressure on the window seals. Furthermore, properties exposed to high winds-- typical across open Hertfordshire fields and raised parts of the city-- might experience sped up wear on window frames and seals.
