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.
Dumbarton
Translating as 'fort of the Britons', Dumbarton is a town in West Dunbartonshire. It is on the north edge of the River Clyde where the River Leven encounters the Clyde estuary in Scotland. Traditionally, Dumbarton was the capital of the ancient Kingdom of Alclud, and afterwards the county town of Dunbartonshire, being a Royal burgh between 1222 and 1975. Dominating the town is Dumbarton Castle, situated on top of Dumbarton Rock, which has a long history, recognised especially for its considerable part in the War of Independence by being the prison of William Wallace after his capture by the English. As a Scheduled Ancient Monument, Dumbarton Rock is officially safeguarded from any sort of work happening on the rock, such as restricting such activities as rock climbing. Dumbarton was bombed on a large scale during the course of the 2nd World War, as the German air force was targeting shipyards, with Clyde and Leven Street being profoundly impacted. Decoy lights were typically put on the Kilpatrick hills above the town and on reservoirs in the attempt to simulate those of the shipyards and to trick the bombers, which had a reasonable amount of success. Whilst Dumbarton was known for its shipbuilding, glassmaking and whisky production, the decline of these markets in the 20th century has actually meant that it is mainly a commuter town for its 20527 residents. The town is home to Dumbarton F.C., playing in the Scottish Professional Football League at Scottish Championship level. The Denny Civic Theatre is used by a range of regional groups, such as the Dumbarton People's Theatre who put on many performances.
