Condensation in Double Glazed Windows

It makes a plenty of sense for you to have double glazed windows for your home. Not only do double glazed windows make your home secure, but also provide you with a much better insulation. This helps to reduce the energy consumption by a considerable extent, which not only has beneficial effects for the environment, but also reduces your monthly electricity bill considerably. But one of the common problems that you may have to deal with is the condensation in double glazed windows. You may want to know how to clean up the windows when this happens, or whether you should get the windows replaced. We discuss all the questions that you may have on dealing with condensation in double glazed windows. Read on for more information.

What causes condensation in double glazed windows?

Usually, the condensation is not caused by the PVC windows themselves, but happens because of faulty sealing in the double glazed unit. Typically the double glazed units are sealed together with the help of a bitumen product. The problem arises when the bitumen used for the sealing breaks down, and the seal gets broken. When this happens, moist air and water vapor penetrates the double glazed unit over a period of time. And suddenly, you will find moisture between the two panes of glass that form your window. This is what causes condensation in double glazed windows.

How do you deal with condensation in double glazed windows?

The very first thing that you shall need to do when faced with this problem is to check the guarantee given to you by the manufacturer of your double glazed windows. Does the guarantee cover the issue of condensation in double glazed windows adequately? If the manufacturer's guaranty covers the issue explicitly, you are in luck and you may contact the supplier of the double glazed windows and have them replaced with new ones. Otherwise, you may have to look around for a few free estimates to get the issue resolved.

But unfortunately, when there is a condensation in double glazed windows, there is just one way to solve the problem – which is to get the entire double glazed unit completely replaced. But it would help you a great deal to understand what caused this problem in the first place, so that it does not occur again in the future.

One of the main reasons that condensation in double glazed windows happens is because of the presence of water within the PVC window – which causes damage to the sealant which is made of bitumen. So the best way to make prevent condensation in double glazed windows is to make sure that windows that are ordered by you have an adequate number of drain holes in them, which allows the water to drained out automatically. Get a technician to check whether your double glazed windows have enough water drains in them before you make the order.

Another reason for the condensation in double glazed windows is the faulty packing of the double glazed windows when they are brought from the store. The problem arises when the double glazed window glass is not laid down perfectly flat on the PVC frame that it comes with. Also, the double glazed windows are fabricated so that there is an easy flow of water through the windows – the water should move out just as easily as it moves in. The way to do this is to place the glass on tiny plastic glass packers as they are installed, so that the glasses are completely unaffected and untouched by the water – the water flows in and flows out, without ever coming in touch with the glasses of the double glazed window.

The same methodology may be used even if the windows are built on aluminum or timber. In fact, these days all windows are designed keeping the above principles in mind, and come with adequate facilities for the drainage of water and are also dotted with air flow holes.

Conclusion

While the only way to solve the problem of condensation in double glazed windows is to have the entire unit replaced, we hope that you have learned enough from this article to get your double glazed windows installed the right way, so that the condensation never occurs in the future. It also helps to buy from manufacturers that provide an explicit guarantee of replacing the double glazed windows if any condensation is seen in them.

Condensation Inside Double Glazing, Repairs of condensation within the cavity of a
hermetically sealed double glazed unit
or Insulating Glass Unit (IGU) denotes
a failure of the seal.
Where the double glazing is achieved
by the installation of secondary glazing,
condensation on the cavity surface of the
outer glass generally (but not invariably)
indicates leakage from moist air from the
room into the cavity. However, the reader
should note that it is not possible to
hermetically seal secondary windows;
therefore some migration of air from the
room into the cavity is to be expected.

Condensation can occur occasionally on
the cavity surface of the inner glass when
the sun is shining on the window. This means
that something in the air space itself, such
as an unsealed wooden separator or
desiccant, contains moisture. It should
be noted, however, that this source can
also be responsible for condensation on
the cavity surface of the outer glass.
