Misty Double Glazing Repair
Misty double glazing happens when the air-tight seal which holds the two panes of glass in a double-glazed window fails. This allows moisture into the window, which reduces its insulation properties.
Getting your windows professionally repaired is more affordable than replacing the entire window. This will save you from any further damage or condensation issues.
Seals
A window seal, otherwise called a uPVC window seal, is the primary element that helps keep your double glazing mist free and in optimal condition. If your window seals become damaged or worn out, they'll no longer provide an airtight insulation, which can cause drafts, energy loss and even a misty glass between the panes of your double glazing.
A damaged window seal could also decrease the efficiency of the thermal system of your home and increase your energy costs. In general, 20% of the heat that is lost in your home is lost through doors and windows and this is more apparent when window seals fail. It's important to repair windows immediately you notice it to minimize the impact.

Sealant
If the seal between the frame and glass has broken down then moisture may enter the frame and cause mist. This is most commonly caused by wear and tear or simply ageing. As temperatures change, the gasses in the double-glazed unit expand and contract which creates pressure on the seal, which causes it to break down over time. This could also be due to inadequate installation or damage that occurs during construction.

A crack or break in the black sealant that holds the glass panes and the silver spacer bars together is the primary reason for a double-glazed unit's failure. This sealant is known as hot melt and is a pretty tough material. If it gets damaged, it can cause air to enter the double glazed unit, causing condensation and a misty window.
To fix a glass that has been misted, you must first remove any sealant that is old. It is possible to use a knife, but it's better to use sealant remover. This will make the job simpler and faster. When using a knife on any kind or pane of glass be cautious not to apply excessive pressure.
Once the sealant has been removed, take the glass's top layer and place it on a flat surface safe where it won't be damaged. Mark the glass's glazed side of the glass using an indestructible marker after the pane is removed. This will assist you to place it back into the correct position.

Glass
Windows are an essential part of any house, providing airflow, light and connection to the outside. However, they can be an important source of energy losses. The gas contained in double-glazed windows can deplete over time, resulting in fogged glass and lower insulation. Regular maintenance and a quality installation can easily prevent this.
Many people believe that a misty double-glazing window means the frame has failed, however this isn't the case. It is typically the seal that is failing, allowing the gas that insulates between the panes to escape. The most effective way to fix this is replacing the sealed unit, instead of replacing the entire window. This is a cheaper option that will save you money over time. It is also a good opportunity to upgrade your windows to energy efficient A-rated glass, which can further boost the savings you make.
Double-glazed windows that fail are referred to as steamed-up windows. This happens when the hot melt sealant which creates a seal between two panes of glass fails. This causes moisture to build up within the window over time. This moisture will then cool and condense into liquid. It can be seen as steam-like streaks on the inside of the double glazed window, and it will appear worse on warmer days.
Initially, the problem may seem to be solved by inserting warm air into the window. Although this can help, it is not an all-time solution. Avoid extreme temperature fluctuations as they can cause condensation. Maintain the temperature as steady as is possible.
