How long your aluminium windows will last depends on their quality. They should last 20 -30 years at least, but have been known to stay in good condition for up to 45 years. This is considerably longer than uPVC and wooden double glazing.
March
March is a Fenland market town and civil parish in the Isle of Ely area of Cambridgeshire, England. March was the county town of the Isle of Ely, which was a separate administrative county in between 1889 and 1965. It is now the administrative centre of Fenland District Council. Similar to lots of Fenland towns, March was once an island surrounded by marshes. It occupied the 2nd largest 'island' in the Great Level. As the land drained, the town established and thrived as a trading and religious centre. It was also a small port before coming to be, in more recent times, a market town and an administrative and train centre. March is situated on the banks of the old course of the navigable River Nene, and today largely used by pleasure boats. The town's development happened most swiftly when it transformed into an essential railway centre. It had a major junction between the Great Eastern Railway and Great Northern Railway at March train station, enabling for ease of access to and from London, Cambridge and Ely. In particular, March Royal Mail sorting office, previously a full post office dates from 1936, is unusual because it is one of a few post offices that display the royal cypher from the brief reign of Edward VIII. There are plenty of shopping opportunities for the 19042 residents of March. March Town Centre is home to a vast array of independent and commercial chain stores. A retail park opened in 2008, extending the capacity to shop in superstores and grocery stores. Distributed across the town are also multiple restaurants, bars and public houses.
