If you are one of those people who still have single glazed windows, you may be interested in discovering some of 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.

Secondary glazed windows can be achieved either by adding an additional pane of glass to an existing window, or by fixing a plastic sheet to the existing window. It is best to have an expert install any additional panes to get the most out of the improvements, but the plastic sheeting can easily be installed by any amateur DIY enthusiast.

Of the many benefits associated with this form of glazing, an improved thermal performance is probably the most significant. A window’s performance can be improved by up to 60% with effective secondary glazing and household draughts can be all but eliminated. With regard to energy saving, windows are the main area of the home from which heat can escape, and better thermal insulation greatly reduces carbon emissions.

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.

In order to avoid bias, it should also be noted that there is one common complaint about secondary glazed windows. If the installation is not carried out to a sufficiently high standard there is a real risk of condensation. It is essential that if condensation builds up, you try to allow enough air circulation to prevent the problem worsening as this can cause the windows to rot from the inside.

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.
