Badly insulated window frames and single glazing can account for up to 20% of the heat loss in the home.

Fitting double glazing around your home can typically save you around £135 a year.

This can obviously be quite costly. However, installing 'Secondary glazing' is another method of reducing heat loss through your windows at a lower cost.  This is simply adding a second layer of glazing to your existing single glazing.
