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.
Bude
Bude is a tiny seaside resort town in north east Cornwall, England, in the civil church of Bude-Stratton and at the mouth of the River Neet (also understood locally as the River Strat). It was occasionally previously called Bude Haven. It exists southwest of Stratton, south of Flexbury and Poughill, and also north of Widemouth Bay as well as is located along the A3073 roadway off the A39. Bude is twinned with Ergué-Gabéric in Brittany, France. Bude's coast faces Bude Bay in the Celtic Sea, part of the Atlantic Sea. The population of the civil parish can be discovered under Bude-Stratton. Its earlier value was as a harbour, and then a source of sea sand valuable for boosting the moorland dirt. The Victorians favoured it as a watering place, and also it was a popular seaside destination in the 20th century. In the 1951 Cornwall volume of The Buildings of England, Nikolaus Pevsner described Bude as "Not an appealing harbour-town compared with others in Cornwall and also Devon", as well as remains to state that the church is "useless".
