At Southern Window Company, we offer all aspects of specialist glazing options.


Secondary glazing involves adding an extra slim-line window in addition to your existing windows. It is a effective & cost efficient method of insulating / sound proofing your windows. If you’re worried about the ever increasing energy costs, then you could save around 10% on your heating bills. The Energy Saving Trust states that it is an ‘ideal solution if you are unable to fit double glazing’.

Secondary glazing is perfect for use in Listed Buildings and conservation areas. Made from strong lightweight aluminium, it can be made to be very slim and discreet. Considered a reversible change, secondary glazing is recommended by English Heritage and the Listed Property Owners Club.


A modern window today is build up by three layers of glass, hence the name triple glazing. Triple glazing is a system of sealed glazing units using 3 sheets of glass. It is the next step up from double glazing.

The aim of triple glazing is to provide better thermal and sound insulation than other forms of windows.



Long described as an impossible dream, self-cleaning glass is now a reality. After years of research and development leading glass manufacturer Pilkington has introduced the Pilkington Activ™ range of products.

The range has products which combine both self-cleaning and solar control properties, making them highly desirable amongst homeowners looking for the ultimate in glass solutions.

Self-cleaning Glass uses the forces of nature to maintain a cleaner and clearer appearance. In a dual-action process organic dirt is broken down by daylight and is then washed away by rain, thus making it environmentally friendly and very easy to maintain.
