The Big Problem Dealing With Secondary Glazing And Condensation Build-Up

July 31st, 2010 No comments

Secondary – and double-glazing are both tried and true methods of making a building more energy efficient. Both will reduce heating and cooling costs and also lessen carbon-dioxide emissions. Both work well but are certainly not equal in their efficiency or functionality. For one thing, there is an on-going problem with secondary glazing and condensation. This is not such a problem with double-panes.

Those who elect to install double glazing can expect to save about one-half of their current energy consumption. Good quality double-glazed windows are extremely efficient at blocking not only heat loss but also air and noise pollution. They will make your home quieter, cleaner, warmer (or cooler in summer) and more comfortable. They’re very good at their job.

What makes double-glazing work so well is the sealed space left between the two panes of glass. This void, which may either contain a vacuum or be filled with air or another gas (usually argon), makes for a very good insulation barrier between you and the outside world. This insulating space must be completely sealed (air-tight) in order to function properly.

Sometimes ‘Low Emissivity’ (Low-E) glass is used, which significantly increases the window’s efficiency. This Low-E coating, applied to one side of the glass pane, is able to keep the heat in your house by bouncing it back when it’s trying to escape through the window. At the same time, Low-E allows the sun’s solar rays through, making good use of the sun’s warmth. It’s a great technological innovation.

Because proper double-glazing will employ an air-tight seal, chances of condensation appearing are minimal. The same cannot be said about secondary glazing, which is one of its shortcomings. Because secondary windows are placed on the inside of existing single-paned windows they just don’t work as well as when the primary window is replaced with a double-glazed unit. Unfortunately, adding double-paned models isn’t always possible.

Prior planning consent is not required in order to install secondary windows. For homes that are listed (or in Conservation areas) this may be the best option. It may, in fact, be your ONLY option.

Secondary glazing and condensation problems associated with this method of upgrading your windows is something to consider. They will also cut your energy bill and reduce your emissions but only about half as much as the double-glazed units. Half, of course, is better than none and, in some cases may be the only alternative. Consider the options.

A Look At Problems With Secondary Glazing And Condensation

July 12th, 2010 No comments

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.

If you wonder why many people prefer double glazed windows in any new installations you may not know that they offer a lot of insulation against both temperature changes and sound. They are particularly useful in a room where there is a lot of glass exposed to the outside air. This can include a glassed in porch or a conservatory. Even a room with a lot of large windows can benefit from double glazed windows.

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.

You can opt to have your windows treated with secondary glazing. They usually involve the addition of a glass insert that fits inside the window. They look like the original window and tend to be very unobtrusive. They can also be applied to a number of different window styles from sliders to tilt style windows. The problem is that when there is a space between the two panes and there is not a glass filler, condensation can become a problem.

Condensation occurs any time when there is water vapor present. It is usually invisible when the air is hot enough. However, should it meet up with a cooler surface such as an external pane of glass, the water can reform into water droplets and end up rotting through a wooden frame.

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.

Managing To Accurately Find The Environmental Benefits Of Secondary Glazing

July 12th, 2010 No comments

If your property still has only single glazed windows, you might be keen to enhance your understanding of what the environmental benefits of secondary glazing actually are.

Prior to looking at why this form of glazing might be considered, it firstly is necessary to define exactly what it comprises. In nature it is very similar to double glazing, but costs less and requires no extra planning permission because no structural alterations are made. This makes it a very neat alternative for the less affluent or those bound by building regulations.

Installation of secondary glazed windows should be carried out by a qualified fitter for best results, but the process is fairly simplistic and anyone with sound DIY experience should be able to do the same job at a fraction of the cost. The two main forms of this glazing are the basic version which is simply a plastic sheet fitted over the existing window, and the more advanced option which is an additional glass pane fitted in a frame added to the existing window.

There are numerous benefits to be gained from upgrading your windows, and an improved thermal performance is one of the main ones. The effectiveness of a window can be enhanced by up to 60% with a well fitted upgrade, and light breezes can be eradicated completely. Most heat lost from the home escapes through the windows and from an environmental viewpoint, an improved thermal insulation system considerably lowers carbon emissions.

With population levels higher than ever before it is not surprising that the noise made from society is also at a peak. It is therefore fortuitous that improved acoustic insulation is another worthy benefit of this glazing. It may seem a minor plus, but doctors report that the stress caused by noise pollution can become so severe that it can lead to a complete mental breakdown, and anything that prevents the erosion of mental health has to be valued.

Security is obviously important to everybody, and the increased protection afforded by just one extra window layer is surprising. A secondary layer can make forced entry from burglars much more difficult, and can also protect against bomb blasts, fire, or gunshots.

For all the practical and environmental benefits, the financial gain cannot be overlooked either. It is estimated that secondary insulation can reduce heating bills by a third, and these savings must be considered when weighing up the cost of installation.

It should also be recognized that there is one potential disadvantage to these windows that can be extremely dangerous if not corrected immediately. A lack of ventilation caused by a poorly fitted window can result in a build up of condensation, which in turn can cause the windows to decay internally. Although this can be fairly common, it is also easily prevented if due care is taken.

Now the environmental benefits of secondary glazing should appear more obvious, and are hopefully a useful guide in helping decide how best to insulate your home or office.

The environmental benefits of secondary glazing are just plain endless. Get the low down on the best sash window company now in our exclusive online secondary glazing London overview.
