What Is Double Glazing and Do You Need it


A person who works with glass is called a glazier and the act of working with glass is called glazing. Therefore, double glazing is the process of working with two pieces of glass. In most contexts, it refers to a window that has two panes of glass instead of just one. Double glazing has become common for all types of windows recently but it is not ubiquitous. There are still many older windows that have only one pane of glass. Why is this important?

Why it Is Important

Double glazing is important because it offers you greater protection against heat transfer. In the context of a building, any part of the building that allows more heat transfer than surrounding materials is called a thermal bridge. In your home or office, windows are one of the most common thermal bridges. Heat transfers more readily through your windows than through your walls.

Doncaster double glazing serves to reduce heat transfer by creating two panes of glass that are separated by a cushion of air. The cushion of air works as insulation.

Air as Insulation

You might not think it, but air is actually a very good insulator. Heat transfers more readily through materials that are solid. So, a cushion of air can actually be very effective at reducing the amount of heat that comes through your windows. A double-glazed window is so effective that it can have a noticeable effect on your heating and cooling costs.

Some recent research has suggested that controlling the amount of heat coming through your windows can reduce your heating and cooling costs by as much as 40%. So, if you do not have double glazed windows, you could be spending hundreds of pounds more than you need to every year.

Good windows with quality window frames will help insulate your home against rising energy costs.
