Why do double glazing windows get condensation

Once you get to the point where you are wondering, 'why is there condensation on my double glazed windows on the inside of the unit? The solution lies in preventing that from ever happening in the first place. This is why Thermawood developed a drainage system that sits underneath the double glazing on a degree slope.

Eliminating the square rebate and adding a system to drain away any moisture is key to preventing condensation from ever becoming a problem in the first place.

What about moisture on the exterior pane of glass — what causes condensation on the outside of double glazed windows? You may see fog form on the exterior surface when you have a temperature change.

For example, in the morning when the temperature outside starts to increase after a cool night. Then, you could see condensation on the glass outside of your home as the water vapour from the outside air forms on the glass.

What about inside your home — what causes condensation on the inside of double glazed windows? You may also get fog on the glass inside your home when you have a temperature change, such as when you turn on the heat or turn on the air conditioning. The interior pane of glass is probably about the same temperature as your indoor air temperature before you put on the heat or cooling, so again, the water vapour in the air is going to stick to the glass.

Nor can it come into contact with the seal because of the special design. Condensation is visible on windows because glass is a non-absorbent surface, and while this may seem like an everyday and harmless problem nothing could be further from the truth.

While condensation on windows is obvious, you are unlikely to notice condensation form on other surfaces such as walls and furniture where it is absorbed. It is on these absorbent surfaces that black mould is likely to grow. Contact our condensation experts today. If you are currently experiencing persistent problems with condensation on windows, here are a few simple solutions to help prevent condensation.

The above DIY solutions are often enough to combat condensation problems on windows, but you may notice condensation becoming exacerbated if your windows are double glazed. If your condensation problems become more severe it may be worth considering professional condensation treatment.

Condensation within double glazing typically suggests that there is a problem with the sealed unit of the windows. This means that a point in the edge seal of the window has failed and is allowing moisture enter in the form of condensation. You often see condensation in double glazed windows because the surface temperature of the window is cooler than the air inside the room.

Where the frames are made of aluminium that is not thermally enhanced it is likely that there will continue to be a level of condensation occurring on the frames. This level will be influenced by management of inside humidity levels and more noticeable in very cold temperatures.

Double Glazing Explained. Does double glazing eliminate condensation? When it cannot retain any more, the moisture then begins to appear as condensation. In reality, the issue could have been there for quite some time but has only become apparent because the desiccant is no longer doing its job. Solution: The appearance of condensation in double glazing is both annoying and undesirable.

If you are experiencing condensation, moisture or large amounts of water between the two panes of glass it is likely the seal has completely failed.

The likelihood is that the units have deteriorated past the point where they are no longer doing their job properly. In terms of fixing this issue, the cause will determine the solution — and the expense involved — but the two main fixes are If the uPVC units are in good condition, you may just be able to replace the sealed units. There are now a number of specialist companies which can repair or recondition each faulty unit.

A special drying agent or desiccant is then pumped or injected in to dry out the air or expel the condensation within the unit. An anti-fogging agent is sometimes used to prevent the build-up of any further moisture before the unit is completely sealed again. Resealing will solve the problem, but may not actually address the core issue. Before undertaking a repair, think about whether the benefits and their expected life cycle will fully justify the expense involved.

Whilst this is obviously the most expensive route to take, it is the best solution if you can afford it and it may provide better value for money in the long term. If you are experiencing condensation in double glazing that you have had for less than 10 years, check to see if your windows are under guarantee. Should you be lucky enough to have one, get in touch with the company who installed the windows and report the problem. If the seal or unit is found to be defective, they should replace it for free.

Do not be tempted to tamper with the units or attempt a repair yourself because this will invalidate your guarantee. Most reputable windows companies now manufacture new units to very high standards and newly-installed windows will have at least a ten-year life span sometimes 15 or 20 years.

Fitting A-rated windows is now standard practice at EYG because we know they help to reduce the likelihood of condensation by reducing heat loss from your home.
