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.
Knebworth
Knebworth is a village and also civil parish in the north of Hertfordshire, England, right away south of Stevenage. The civil parish covers a location in between the towns of Datchworth, Woolmer Green, Codicote, Kimpton, Whitwell, St Paul's Walden as well as Langley, as well as includes the village of Knebworth, the small town of Old Knebworth as well as Knebworth House. There is evidence of people staying in the area as far back as Neolithic times and also it is discussed in the Domesday Book of 1086 where it is described as Chenepeworde (the farm coming from the Dane, Cnebba) with a population of 150. The initial village, now called Old Knebworth, created around Knebworth House. Development of the more recent Knebworth town started in the late 19th century centred a mile to the east of Old Knebworth on the brand-new railway station as well as the Great North Roadway (subsequently the A1, and currently the B197 since the opening of the A1(M) motorway in 1962). At the turn of the century the architect Edwin Lutyens built Homewood, southeast of Old Knebworth, as a dower residence for Edith Bulwer-Lytton. Her little girl, the suffragette Constance Lytton also lived there, up until right before her death in 1923. Knebworth has, given that 1974, been famously related to numerous major open air rock and pop concerts at Knebworth House, including Queen's last real-time performance which happened on 9 August 1986 as well as attracted a presence estimated at 125,000, Lynyrd Skynyrd, Oasis playing to a quarter of a million individuals for 2 nights in 1996 and even more just recently Robbie Williams, that for 3 nights in August 2003 performed to the largest crowds ever before assembled for a single entertainer.
