- 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.
Deal
Deal is definitely a town in Kent, England, UK. It lies on the English Channel 8 miles north-east of Dover plus eight miles south of Ramsgate. It's a former fishing, mining and also garrison town. Strongly connected with Deal are the communities of Kingsdown, Sholden and Walmer, the second being exactly where Julius Caesar first of all arrived in Britain (based on the very best guess by researchers).
