We all know the basic function of a window and why we think it’s important to the design and functionality of our home – to let in the light and allow us to see our surroundings.
But have you ever considered glass that does more than those basic functions? Well that’s where double-glazed glass comes in.
So, first things first. What is double-glazed glass?
Put simply, double-glazed glass (also known as Insulated Glass Units) comprise of two or more panes of glass, separated by an air (or gas) filled cavity that is completely sealed -forming a transparent insulating barrier between the interior of your space and the outdoors.
Once the glass is double glazed it provides a myriad of benefits, that a standard single glazed window just can’t compete with.
So what exactly are these benefits?
1 Illuminate Your Space
Allows for larger window spaces, opening your home up to more natural light and vaster views.
2 Year-round Comfort
Double glazing provides superior insulation by limiting the transfer of hot or cold air through windows – making your home cooler in summer and warmer in winter. This allows you to have expansive glazing whilst still achieving an energy efficient home.
3 Reduce Outside Noise
The double glazing provides enhanced acoustics, creating a seamless transmission of light through your windows while restricting the amount of external noise reaching inside. No noisy neighbor problems here!
4 UV protection
The sun can glare down on double glazed glass and your items inside including your lounge will not fade, the glass offers UV protection against the suns harsh rays! Amazing.
5 Enhanced Security
Because there are not one but two layers, double glazed glass is built tough. Due to its thick nature when subjected to force the glass won’t crack or shatter easily like normal glass.
Who knew all this could be achieved by the humble window?

Triple Glazing
The aim of triple glazing is to provide better thermal and sound insulation than other forms of glazing.
The effect of adding another layer of glazing is more glass and components for heat to travel through to escape through the window, therefore triple glazing is often a more energy efficient glazing unit.
To maximize the insulating effect, the optimum gap required between the panes is about 16mm. Too close together results in radiant heat loss, too far apart leads to creation of gas currents which causes convection current heat losses.
The gap should be filled with inert gas as this provides greater insulation than air due to low thermal conductivity. Argon is commonly used as it is cheap to produce and is about a third better as an insulator than air. Krypton is used in the highest specification units as it has double the insulation property of air. Krypton is however very expensive compared to Argon.
At least the inner, and ideally also the middle pane should have a low emissivity coating. The effect of the coating is to allow short wave length sunlight to enter a room and heat it, and to achieve a large reflection on the long wave length sunlight, thus the window minimizes the existing heat loss that exists around all windows.
Low emissivity coating is normally made up of a thin layer of metal which is applied straight onto the glass, or in certain cases onto a plastic film that is attached to the glass. The type of metal used to coat low-emissivity glass will affect the characteristics of the triple glazing.
Most glazed units use glass panes of the same thickness, but this is not a necessary requirement. Most commonly, a triple glazed unit glass specification is 4mm glass on the inner and outer panes and 4mm glass in the middle. Suppliers may also insist on using tempered glass on the middle pane to help the unit to cope with the increased stress on the centre pane that can be caused by deflection.
