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.
Moreton-in-marsh
Moreton-in-Marsh (population 3,493) is a small market town in the Evenlode Valley, within the Cotswolds Area of Outstanding Natural Beauty in Gloucestershire, England. The community stands at the crossroads of the Fosse Way Roman road (currently the A429) and the A44. It is served by Moreton-in-Marsh railway station on the Cotswold Line. It is reasonably flat as well as low-lying compared with the surrounding Cotswold Hills. The River Evenlode increases near Batsford, runs around the side of Moreton as well as meanders in the direction of Oxford, where it streams into the Thames just east of Eynsham. Simply over 1.5 miles (2.4 km) east of Moreton, the Four shire stone marked the border of the historical areas of Gloucestershire, Warwickshire, Worcestershire as well as Oxfordshire, till the re-organisation of the region borders in 1931. Since then it notes the gathering place of Gloucestershire, Warwickshire and also Oxfordshire. Moreton is derived from Old English which means "Farmstead on the Moor" and "in Marsh" is from henne as well as mersh suggesting a marsh used by birds such as moorhens. An alternative idea is that 'Marsh' is a corruption of 'March', early English for limit.
