- Climate - If your window faces south, it will be subject to direct sunlight for a lot of the day. This tends to cause the sealed unit to fail more quickly – a south-facing window may last between 10-25 years. This is because the spacer bars will twist as the temperature rises and causes the adhesive holding them together to eventually fail.
- Moisture - Windows in kitchens and bathrooms tend to fail more quickly because they come into contact with moisture more often. For example, if water gets on your windowsill when you shower, the seal around the glass will come loose more quickly if it’s constantly wet.
Brecon
Brecon, archaically called Brecknock, is a market community as well as neighborhood in Powys, mid-Wales. In 1841, it had a population of 5,701. The population in 2001 was 7,901, raising to 8,250 at the 2011 census. Historically it was the county town of Brecknockshire (Breconshire); although its role thus was overshadowed with the development of the County of Powys, it stays an essential regional centre. Brecon is the third-largest community in Powys, after Newtown and also Ystradgynlais. It exists north of the Brecon Beacons chain of mountains, but is just within the Brecon Beacons National Park.
