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.
Appleby-in-westmorland
Appleby-in-Westmorland is a market town and also civil parish in the Eden district, in the management area of Cumbria, in North West England. The church had a population of 3,048 in 2011. It lies in a loop of the River Eden in the historical area of Westmorland, of which it was the county town. Its name was merely Appleby up until the city government adjustments of 1974. When a successor parish was developed from the previous borough, the council altered its name to tape that of the historical region. Appleby is 13.7 mi (22 kilometres) south east of Penrith, 32.2 mi (52 km) south eastern of Carlisle, 27.2 mi (44 kilometres) north east of Kendal, 45.2 mi (73 kilometres) west of Darlington, as well as 61.2 mi (98 km) west of Middlesbrough. Appleby is overlooked by the privately owned Appleby Castle, a largely Norman framework that acted as house for Girl Anne Clifford in the 17th century. Appleby's primary industry is tourism, as a result of its history, remote location, surroundings and distance to the Lake Area, the North Pennines, Swaledale and Howgill Fells. From 1973, Appleby Castle was the head office of Ferguson Industrial Holdings Plc. WA Advancement Limited, currently Stobart Rail Limited, was long based in Appleby as a civil design firm established by Andrew Tinkler and William Stobart and specialising in train maintenance.
