People today are choosing more and more to opt for double glazed sash windows as they combine the traditional beauty and charm of sash windows with the energy efficiency and security desired in a modern home.
Double glazed sash windows work by combining two layers of glass which are separated by a tight air pocket. The first piece of glass in these double-glazed sash windows serves the same purpose as the glass in a normal, single glazed window. However, when you combine this with a second pane of glass, this provides twice the noise barrier. There is a gas in the air pocket between the two pieces of glass called argon which is a poor heat conductor, this is because the trapped air has no room to circulate in order to conduct and transfer heat. The inside glass layer has a low-E coating which reflects heat back into the room. All these features in double-glazing work together to ensure that the warm air from your house is kept in, making them more cost-effective and energy efficient than single glazing. Thus, adding value to your property.
As well as the energy efficiency gained by double-glazing, the second layer of glass added to make a double glazed unit combined with modern toughened glass makes smashing through a double glazed sash window very difficult. This significantly increases safety and security in your home.
