Secondary Timber Glazing

Many properties from the Victorian and Georgian era were built with timber sash windows and are still in existence today due to their beauty and how they enhance and retain the value of a property. Often, timber sash windows are constructed with singular panes of glass within a wooden frame and two are placed vertically away from each other. Whilst this allows ventilation through the small gap, which is great during the summer months, it can also allow noise to enter the room and lose heat during the colder winter months.

Secondary timber glazing has been designed with period properties in mind, so that the original window can remain and the noise pollution problem be solved. This is particularly important for listed buildings where the style of original window cannot be changed.

Secondary timber glazing is where an internal timber glazed unit is made to the exact same frame size and can either be hinged or sliding, and sits inside of the original window. This allows space between the two frames for sound insulation as well as heat preservation.  The frames are usually painted to match the existing window frames so that they blend in easily.

Secondary sash glazing has many advantages. It will reduce heating costs which is not only good for the pocket but also for the environment. The reduction in noise will also enable the whole house to obtain a good night’s sleep.  By having the secondary glazing fitted, there will be a significant reduction in condensation which will minimise damp issues within a property. Another good reason for considering secondary timber glazing is the added security to the property. Furthermore, as the original windows have not been replaced, considerable costs have been saved by not having to have the property redecorated which would have been necessary after the fitment of new windows.
