There are many different types of windows including single glazed and double glazed windows. Many times, people will install single glazed windows in their home but then want the additional benefits that a second layer of glazing can give them. There can be problems with secondary glazing and condensation that you need to be aware of. Here is information about windows in general and what you need to look for if you do decide to add secondary glazing to your wooden windows.
Double glazing can offer a lot of benefits. They can add insulation against sound and can help you save on energy bills. If you have a room such as a conservatory or sun room and you want to add extra insulation, double glazing may be an option that you want to look into.
The good news is that the same issues that surround secondary glazing are not usually present in double glazed windows with intact seals. This is because a window that is double glazed is actually filled with insulating glass that keeps moisture out rather than secondary glazing where there is no gas layer present.
Secondary glazing is created in a slightly different way. Working with an existing window, a second thin layer of glass is added, usually in a separate frame. It is often created in such a way that it is identical to the outside window. The problem is that unlike double glazing, there is no gas layer other than a layer of air. Since air can hold moisture, this can be a problem where condensation is concerned.
Condensation is a natural process that happens when water vapor in the air and in our breath meets a cooler surface. It is not usually a problem if there is a way for the water to evaporate again. However, if it sits on a wooden surface such as a wooden window frame, over time the wood will rot and the window will be destroyed. If this happens in your windows, they can be extremely expensive to replace.
You may not even notice this interior rot until it is quite advanced. Therefore the best option is to simply provide a space where water vapor can escape. This means either drilling a small ventilation hole or ensuring that the window has a small space where the vapor can get out.
By taking care of your windows and ensuring that moisture does not have a chance to build up you will ensure that they will stay in top condition for as long as possible. Then, over time you can choose to convert to double glazed windows if you so choose.
