Trying To Best Explore The Environmental Benefits Of Secondary Glazing

By Glen Middleston


The likelihood is that if you have single glazed windows in your home, you will benefit from looking at the environmental benefits of secondary glazing.

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.

There are two main ways in which to install secondary glazed windows. The best way is to add an extra pane of glass to your existing window, but the fitting of a plastic sheet can also form an effective barrier. If you are handy at DIY you may even install the glazing yourself, although professional expertise is recommended.

Greater thermal performance is generally considered to be the main advantage of these windows as an increase in efficiency of up to 60% is obtainable and troublesome draughts can quickly be remedied. As most energy conscious environmentalists know, the majority of heat lost in the home is through the windows, and carbon emissions can be significantly reduced by fitting a secondary window.

As well as thermal insulation, acoustic insulation can also be substantially improved. In the hectic society we live in, noise can be a major source of annoyance and whether it comes from traffic, music, or general hustle and bustle it can lead to increased amounts of stress. In reality noise pollution can actually have a seriously detrimental impact on health, and the benefits of reducing this should not be underestimated.

Greater protection is also provided as the stronger barrier can prevent unwelcome guests from breaking in via the window. Gunshots, explosions and fires are also less likely to penetrate a strengthened window, and those more concerned with security will find peace of mind an unexpected advantage.

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.
