If there is condensation inside the glass of your double glazing or it appears misty and foggy, this means that the sealed unit has failed.

This happens when the gas inside the glazing unit has depleted. The good news is that Locksmith Rotherham SheffLOCK can replace misted double glazed units. Even when the unit is decorated with a leaded window pattern, they can still be repaired to match the existing design.

Double glazed windows are made up of 2 panes of glass, separated by a spacer bar to create a gap. As you would expect, triple glazing is made up of three layers of glass with greater heating and sound insulation properties.

The internal gap needs to be measured, as well as your window panel size, in order to get the right fit panel for your needs. The gap between the window panes can be filled with an inert gas, usually argon which has better insulationg properties than just air. Each double glazed unit is sealed with a hard wearing sealant tape.

If the inside of the glass unit is misty and has condensation inside the window it is known as a blown or misted unit. It is possible to replace a sealed unit, and advise a professional window fitter to carry out work as home insurance policies will not cover any injuries associated with repairing or replacing double glazing units.

What causes misted windows?

Over time small changes in temperature can cause the glazed unit to expand and contract, which can result in gas escaping from the sealed unit.

Double glazing is made up of two glass panels with an airtight seal, filled with an inert gas. Argon gas is used widely as it has good thermal and sound insulationg proeprties. A damaged seal can cause the gas to escape through chipped or cracked glass. Poorly maintained double glazed units can cause sgnificant heat loss in the room.

If you have a lead pattern on your double glazing panels, these can be reproduced onto new panels. We can replace leaded windows with clear glass sealed units or we can replace clear panels with new lead patterned glass panels.

Misted windows present themselves when one side of the glass is warm and the other side of the glass is cold with water condensing onto the colder surface. Desiccant within spacer bars become saturated and can no longer dry the moisture between the double glazed window panels. To prevent the problem from occuring you can keep these tips in mind.

Air Flow

Keep a constant air flow and consistent temperature to avoid any internal surface condensation problems.

Curtains and Nets

Maintain a gap between the curtains and the glass surface. Curtains that are too close without adequate air flow can cause dampness and condensation on the window panels.

Bathroom doors

Keep your bathroom and dedroom doors closed after taking a bath or shower, as the steam can travel throughout the house to bedroom windows and cause condensation.

Drying Clothes Inside

Try to avoid hanging clothes to dry inside, especially on radiators with the windows closed. The clothes dry quickly, but the water vapour increases moisture in the atmosphere and cools on the double glazed panels into liquid droplets.


Good ventilation in a kitchen is important. A cooker hood fan should be put on the same time heat in applied. It take a few minutes for the cooker hood fan to build up a vacuum to suck the steam out. In the coldest part of winter you want to close all your windows but if you dont have a cooker hood fan try to keep a window open when using open top pots and pans, as the steam will cool down on windows to become water droplets. These will eventually appear on the inside of your double glazing panels.

De-humidifier Solution

De-humidifiers are a solution for keeping moisture under control. These can help prevent serious health issues caused by mould and dampness. Consider a de-humidifier in any room when you get condensation on double glazed windows.
