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.

One secret behind the effectiveness of a double-glazed window is the space between the two panes. This acts as an insulating barrier and, if properly sealed, will be very efficient in insulating that huge hole in your wall called a ‘window’. This space may be filled with air or an inert gas (such as argon). It can also sometimes be void with a slight vacuum maintained in the space.

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.

Besides the problems associated with secondary glazing and condensation there is also the inconvenience of this type of arrangement to be taken into account. You may want to remove these secondary windows during the summer months, which means finding a storage area for them. Also be aware that these types of windows will normally make escape from the house in an emergency more difficult.
