The reason for double glazing was to save homeowners on energy costs by insulating their homes better. Insulated glass is made up of two panes of glass connected with spacers and filled with inert gasses such as the xenon or argon, to decrease heat transfer. If the window seal fails the insulating gases are released, making windows less efficient at preserving energy.

It is essential to replace seals as soon they become damaged to avoid these problems. Glaziers can replace the seals quickly, effectively and efficiently, to ensure that your double glazing is in good condition.
Certain glazed windows come with a warranty which covers the cost of replacing the window seals in the event that they break. Ask your glazier what their policy on this is and how long they guarantee the warranty for. If you have a guarantee, it is recommended to notify them immediately if you spot any indication that your window seal is failing.
