Double Glazing

What is double glazing

Quite simply double glazing refers to the use of two panes of glass in a window, the space between two panes is filled with gas which acts as a insulator, in our case that gas is Argon. The reason so many people choose double glazed windows is that it can make a huge difference to their home in terms of reducing heat loss and energy bills whilst it also reduces noise interference.

How does it work?

Double glazing works by creating an insulating layer between the outside and inside of your home. Our double glazed windows are filled with Argon glass which is extremely good at reducing the transfer of heat.

Here is a simple explanation for you. It’s like an environmentally friendly jam sandwich! In A-rated Safestyle double glazed windows, the ‘bread’ is two types of modern AGC energy efficient glass, designed to control the flow of heat through the window so that your home stays warmer. The ‘jam’ is a cushion of air in our windows a special inert gas (found naturally in our atmosphere) called Argon. “Inert” means that it is safe and non-reactive – that’s why Argon is known as the lazy gas. Argon really does nothing and that’s what makes it so great for double glazing . It drastically reduces the mobility of heat moving through it. This means that heat stays in your home for longer. 

GenimageDifferences in double glazing

Not all double glazing is equal when it comes to cutting the heat loss from your home. An energy efficiency rating system is applied to all double glazing products to measure how effective they are at reducing heat loss. Some standard double glazing windows may for example start at a C rating and offer some level of protection. However our  Eco Diamond windows are A-rated. As such they are actively recommended by the Energy Saving Trust for their excellent energy efficiency properties.

Why choose double glazing vs. triple glazing

The majority of the energy saving benefit is made in the step from single glazed windows to A-rated double glazing. Whilst there are incremental savings to be made from triple glazing those savings often, in our experience, don't outweigh the additional up-front costs. Our recommendation is that double glazing strikes the optimum balance between cost and energy savings. We would only recommend triple glazing for a few cases such as living close to a very busy flight path where there are extreme requirements for sound reduction.
