The London Borough of Lewisham is a London borough in south-east London, England and forms a part of Inner London. The borough wasestablished in 1965, by the London Government Act 1963, as an amalgamation of the former location of the Metropolitan Borough of Lewisham as well as the Metropolitan Borough of Deptford, which had been established in 1900 as divisions of the County of London. However, minor boundary modifications have occurred since its creation. One of the most significant amendments were made in 1996, when the previous part of the Royal Docks in Deptford was transferred from the London Borough of Greenwich.
The local authority is Lewisham London Borough Council and it's based in Catford. The borough covers an overall area of about 13.57 square miles. It is surrounded by the Royal Borough of Greenwich to the east, the London Borough of Bromley towards the south and also the London Borough of Southwark towards the west. The River Thames forms a short section of northern boundary with the Isle of Dogs within the London Borough of Tower Hamlets. Deptford Creek, Pool River, River Quaggy and River Ravensbourne pass by means of the borough.
As outlined by population estimates made during 2014, Lewisham is a borough with approximately 291933 permanent residents. Around 43 per cent of households are owner-occupiers. The Prime Meridian passes through Lewisham. Blackheath, Goldsmiths, University of London and Millwall F.C. are positioned within the borough.

The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.
As well as keeping your home warmer and reducing noise, you’ll notice a saving on your energy bills from installing double glazing. If you install A++ rated windows in your home after having single glazing, you could save up to £120 year on your energy bills. The Energy Saving Trust has more information.
Some properties are unable to have double glazing, especially those in conservation areas or listed buildings. To counter this problem and still benefit from a warmer home and cheaper bills, secondary glazing is an option. Secondary glazing is a second pane fitted inside your original window. Secondary glazing will still save you around £105 yearly.
Just like every other thing in your house, your double glazed windows have an expected lifespan attached to it as it gradually becomes less functional and less efficient over time. Although there are actually top quality windows which are able to last a very long time, but the fact still remains that nothing can stand the test of time or last forever. Even the best quality double glazed windows will eventually need to be replaced at some point. So exactly how long do double glazing windows last before need a replacement?
To make it brief, most double glazing window units are typically expected to last an average of 20 years. This number of years can, however, vary within the range of 10 to 35 years based on the several factors such as the type, quality of materials as well as installation and where the windows are located.
The reason for the depreciation in double glazing windows is, over time, the windows may be subjected to some wear, tear as well as all kinds of minor damages which includes gas filled insulated glazing unit slowly and gradually leaking. According to the Centre for Sustainable Energy, the evaporation of 25 percent of gas will ultimately minimize the windows’ thermal performance. And when this occurs, fitting a secondary glazing measure or replacing the windows should be put into consideration.
Another factor leading to the gradual depreciation in double glazing windows over time has to do with condensation. When the window collects between the layers of glass due to the failure of the seal of the perimeter and the saturation of the desiccant, can only be solved by IGU replacement.
And finally, the ravages of time also has a way of taking its toll on double glazing windows. This can happen in so many ways such that the window becomes a lot less efficient and later needing to be replaced.
