For property owners in the historic and attractive city of St Albans, keeping a home is a labour of love. From period cottages near the cathedral to modern builds on the outskirts, every home needs care and attention. Nevertheless, one typical family problem typically captures homeowners off guard: misted-up double glazing.

If you have looked out through your living space or cooking area window recently only to discover a stubborn haze, condensation caught between the glass panes, or a milky film that refuses to wipe away, you are dealing with a stopped working double-glazed unit.

Just what is a Misted Glass Unit?

To comprehend the issue, it helps 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 tightly around the edges with a main and secondary sealant. Inside the spacer bar lies a desiccant (a drying agent) created to absorb any recurring moisture trapped during manufacturing.

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

1. Outside air and moisture leak into the cavity between the panes.
2. The desiccant ultimately ends up being saturated and can no longer soak up the inbound wetness.
3. When temperature level variations take place, this trapped moisture condenses on the interior surfaces of the glass.

Because this moisture is trapped inside the sealed unit, no quantity of cleaning up the inside or outside of the window will make it disappear.

This continuous growth and contraction locations enormous pressure on the window seals. In addition, properties exposed to high winds-- common throughout open Hertfordshire fields and elevated parts of the city-- might experience accelerated wear on window frames and seals.
