Double glazed windows are made out of two glass panes that have a space between them. The design is meant to reduce heat loss in the building. To achieve that, the space between both glass panes — which is often narrower than a finger — is left as a vacuum or filled with an inert gas like argon.
In either case, double glazing can reduce noise and heat loss by up to 70%. And as you can imagine, you don’t need to stop at “double.” Triple and quadruple glazing solutions are also available in the market. Whether or not going for more than two panels is worth the cost depends on the context of the application.
For a typical household, double glazing can be sold as an investment. The money you spend on double glazing now will be saved later in reduced heating costs. If you want a sense of how much this will cost you, this company offers double glazing Forest Hill. Try reaching out to them.
