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.
Kirriemuir
Kirriemuir, occasionally called Kirrie, is a burgh in Angus, Scotland. Its history reaches back to earliest recorded times, when it is thought to have been a major ecclesiastical centre. Later it was identified with witchcraft, as well as some older residences still feature a "witches stane" to ward off bad. In the 19th century, it was an essential centre of the hemp profession. The dramatist J. M. Barrie was born and also buried below, and a statuary of Peter Pan stands in the community square. Though its significance as a market town has reduced, its former hemp manufacturing facilities (now manufacturing synthetics) echo its importance in the 19th century as the centre of a home-based weaving industry. Historical attributes near Kirriemuir include a sculpted Pictish stone known as the Eassie Stone, located in the bed of a melt near the village of Eassie. Kirriemuir asserts the narrowest public footpath in Western Europe; Cat's Close, situated between Grant's Pend as well as Kirkwynd. It is a mere 40 centimetres (15.75 inches) vast. The family members estate of Sir Hugh Munro, who developed Munro's Tables of Scottish mountains over 3,000 ft in altitude (which are currently called "munros"), is likewise located near the town, as is Kinnordy House, the seat of the Lyells.
