Why Double Glazed Windows Affect Energy Efficiency

Windows were once simply holes in the wall of many ancient houses.  During those times, the weather and general climate of the world was probably friendlier as compared to what we have today.  Windows were now dressed with glass and can be opened and closed at a person’s will.  Not only does it provide privacy but it also makes a home a lot safer.

So how do double glazed windows affect energy efficiency?


In order to understand how double glazed windows can improve energy efficiency, you first have to understand how it is built and how each part affect heat insulation.  Let’s first talk about the frames of double glazed window.  Typically, window manufacturers prefer to use uPVC as the material of their double glazed window frames.


uPVC is a lot cheaper to manufacture than aluminium and wooden frames and they offer more benefits to the user.  They’re long lasting, durable, and its colour does not fade even after a number of years.  Moreover, the security it offers is top-notch.


Now let’s get on to the glass pane of the window.  There are two glass panes used in a single double glazed window.  These glass panes have the air in between them, a gas such as argon or another inert gas, that improves heat insulation.  The glass panes and the air are sealed in by the uPVC frame.  With this kind of mechanism, heat transfer will be difficult because of the air between the glass panes.
