- 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.
Selkirk
Selkirk is a town and also historical royal burgh in the Scottish Borders Council district of southeastern Scotland. It lies on the Ettrick Water, a tributary of the River Tweed. Individuals of the town are referred to as Souters, which suggests cobblers (footwear manufacturers and healers). At the time of the 2011 census, Selkirk's population was 5,784. Selkirk was formerly the county town of Selkirkshire. Selkirk is just one of the earliest Royal Burghs in Scotland and is the site of the earliest settlements in what is currently the Scottish Borders. The community's name indicates "church by the hall" from the Old English sele ("hall" or "chateau") and cirice ("church").
