One of the best ways of preserving the elegance of your original windows is with secondary glazing in Ireland and the UK. Property owners, architects and contractors choose secondary glazing as it is warm, secure and quiet.

We offer 3 types of secondary glazing: 

• timber sash,
• timber casement,
• steel casement. 

The best solution will depend on your existing window and it’s internal dimensions.

What is secondary glazing?

Secondary glazing is a new slim-profile, single-glazed window fitted inside the original window frame. It will sit approximately 80-120mm from the original window. In the case of casement secondary glazing, they will open inwards to allow for ventilation and cleaning. Moreover, it is important to note that we will match a sliding sash to the exisitng window so that the rails will be at the same level. Also, the window profiles will be matched exactly in each case.

Secondary Glazing and Protected Structures

This type of glazing is particularly useful with protected structures when the single glazing must be kept intact yet you require a higher level of thermal efficiency, acoustic protection or security. The original windows are conserved in their original designs and the secondary window will provide that extra layer of protection.

Advantages of Secondary Glazing

Warmer – the extra window eliminates any draughts from the original window. Additonally, the trapped air in the gap between the 2 panes of glass acts as an extra layer of insulation.

Quieter – noise levels are dramatically reduced with secondary glazing offering one of the most effective solutions on the market today.

More secure – the additional glazng provides an extra layer of defence against intruders.

Will secondary glazing stop condensation?

Secondary glazing will not stop condensation completely. However, it will reduce it as the extra pane of glass will provide another barrier against heat loss and cold bridging.
