Double glazing is made up of two layers of glass, with a layer of argon gas in between. This type of glass can be used in Aluminium windows. The gas is a poor insulator, helping heat to stay in your home and making your windows more efficient. As well as trapping the argon gas, the second layer of glass reduces the amount of noise that enters your property, and helps to make your windows stronger and more secure.
Aberdeen
Aberdeen is Scotland's third most populated city with an official estimate of 228,990 people. The city and the surrounding area has had inhabitants for at least 8,000 years. It is often nicknamed the Silver City because the granite buildings sparkle after it has rained. This is because of the high mica content in the local granite.
Aberdeen started as two separate burghs. There was Old Aberdeen at the mouth of the River Don, and New Aberdeen which was a fishing and trading village. The two areas of the city joined together in 1891. Old Aberdeen still has its ancient charter from 1179 but is not officially independent any more.
The city has won the Britain in Bloom competition a record 11 times. It also presents the Aberdeen International Youth Festival, which is a principal event where young performing arts companies come to show their capability.
In 2012, the consulting firm Mercer dubbed Aberdeen as the 56th most liveable city in the world and the fourth most liveable city in Britain.
