- 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.
Isle Of Scalpay
Scalpay is an island in the Outer Hebrides of Scotland. Scalpay is around 4 kilometres (2.5 miles) long and rises to an elevation of 104 metres (341 feet) at Beinn Scorabhaig. The location of Scalpay is 653 hectares (2.52 sq mi). The primary settlement on the island goes to the north, near the bridge, clustered around An Acairseid a Tuath (North Harbour). The island is peppered with tiny lochans. The largest of these is Loch an Duin (Loch of the Fort) which has a little island in it, with the remains of the fort still noticeable. Eilean Glas, a little peninsula on Scalpay's eastern shore, is residence to the very first lighthouse to be built in the Outer Hebrides. Scalpay's local neighbor, Harris, is just 300 metres (980 feet) away across the tightens of Caolas Scalpaigh. In 1997, a bridge from Harris to Scalpay was built, changing a ferry solution. In 2001, the island had 322 people, whose primary employment was fish farming and also prawn angling. By 2011 the population had actually declined by 9% to 291 whilst during the same duration Scottish island populations in its entirety grew by 4% to 103,702.
