A cool, metal oxide coating is applied to clear or tinted glass, so that the appearance and performance are the same regardless of glass thickness. Low-e glass brings out the best that technology has to offer for improving your views and comfort! Low-E glass typically costs about 15% more than ordinary glass, but it reduces energy use by as much as 30–50%, by using most of the heat gain in winter but keep the harmful UV rays out during the summer, and when used in insulated glass units - can have even better benefits. For hot climates, low-E coating should be applied to the outside pane of glass. If the windows are designed to provide heat energy in the winter and keep heat inside the house typical of cold climates, the Low-E coating will maximise benefit by being on the inside pane of glass. Low-e glass is recommended by many energy efficiency experts as a result of high performance combined with aesthetics.
Window glass was revolutionized in the 1970’s. Insulated glass (two or more pieces of glass with an air space between) made its debut in the early 70s. Low E glass was introduced in 1979. The E stands for Emissivity. Low E glass works by reflecting heat back to its source. This is done by utilizing an ultra thin metallic coating on or in the glass.
Among other things, sunlight contains visible light, UV light, and infrared (IR) light. Visible light enables us to see things. Ultraviolet light damages your skin, wood, fabrics, leather and causes colors to fade. Infrared light is basically heat. Low E glass has the ability to allow visible light to pass while blocking certain amounts of UV light and IR light.

The infrared light in sunlight is powerful – affected objects become hot. These objects can be your tile floors, furniture, sidewalks, patio furniture, etc. As these objects cool off, they emit a low powered form of IR light.
Low E glass reflects this form of energy. In the summer this helps to keep your house cooler, as the heat from objects outside is kept outside. In winter, all objects in your home are heated (by either the sun or your heater). This heat is also bounced back into your house by the low E glass.
There are two types of low E glass: hard coat and soft coat. Tin is applied directly to the molten glass to make hard coat low E glass. It is hard to scratch the tin off the glass. The soft coat process commonly involves the application of a thin layer of silver while the glass is in a vacuum.
Because this type of coating is delicate, soft coat low E glass is always sandwiched with another piece of glass. It can also oxidize if exposed to air. Argon gas is sometimes used to prevent this oxidation.This gas also acts as an additional insulator.

Low E glass helps to eliminate condensation on glass. The inside surface temperature of the glass is warmer. The differences can be dramatic. Imagine a cold night with an outside temperature of 0 degrees and a 15 mph wind. The inside temperature of a single pane window would be approximately 26 degrees. Regular double pane glass might register 35 degrees. Hard coat low E glass would be very near 49 degrees. And weighing in at champ would be soft coat low E glass at 62 degrees.
Some glass manufacturers have gone even further. They have suspended thin, low E transparent films in between pieces of glass. This system has excellent performance characteristics. Some of these films can block 99.5 percent of UV light. Some boast an insulating value twice that of soft coat low E glass. Low E glass is worth the price, especially since houses can loose 40% percent of the home heating or cooling through windows. That’s why it is worthwhile to purchase the highest quality low-E glass you can afford.

Toughened Glass |
|
![](./Bushfire-Double-Glazed-Windows-Toughened-Glass-Sydney-NSW.jpg) |
Also known as tempered glass, it is a type of safety glass that has increased strength and will usually shatter in small, square pieces when broken. It is used when strength, thermal resistance and safety are important considerations. At home you are likely to find toughened glass in the shower and sliding glass patio doors. For commercial structures, it is used in unframed assemblies such as frameless doors, structurally loaded applications and where there is a danger of human impact. Toughened glass is typically four to six times the strength of annealed glass.

Laminated Glass |
|
![](./Acoustic-Windows-and-Doors-Laminated-Glass-Sydney-NSW.jpg) |
Is a sandwich made of one thin layer of plastic Poly Vinyl Butyral between two or more sheets of glass. The PVB sticks with the glass, forms chemical as well as mechanical bonds. When laminated with annealed glass, the layer maintains the geometric integrity of the pane in case of breakage. Also, it gives acoustic insulation as well as providing protection against damage caused due to UV radiation because it cuts almost 99% of UV radiation present in the sunlight.

Tinted Glass |
|
![](./Soundproof-Windows-and-Doors-Tinted-Glass-Sydney-NSW.jpg) |
Ordinary tinted glass is popular because it reduces heat gain and carbon emmissions, although it also marginally reduces visible light transmission. High Performance or Low-e tinted glass or spectrally selective tinted glass reduces solar heat gain to below that of ordinary bronze/ gray tint but has a visible transmittance closer to clear glass. The tint has little effect on the U-factor but reduces solar gain considerably, which can reduce the need for air conditioning in the summer. Tinted glass is useful in controlling glare - especially for those windows facing east or north east. Return the sunlight not glare into your home.

IGUnit Glass |

or Double Glazing is described as two or more lites of glass spaced apart and hermetically sealed to form a single glazed unit with an air gap between each lite. As the name suggests, the most important function of and IGU is to improve the thermal performance of glass when used in architectural applications. It is common to find two panel of glass and they are therefore also referred to as double glazing units. Triple glazing units are rare but serve their owners well in very cold climates. Insulated glazing may be framed in a sash or frame. IGU made of glass is called insulated glass.

Handling and Storage |
|
![](./Secondary-Double-Glazing-Handling-and-Storage-Sydney-NSW.jpg) |
After the double glazed windows are delivered to your home or the construction site, ideally they should be installed as soon as possible, to minimise the risk of accidental damage. However, we understand that this may not be practical if there are other renovation or construction work being completed - in this case, it is best to store the double glazed window/ door frames and glass separately and in an area with limited access, so that the upvc window frames and insulated glass units experience the least movement possible.

Sealing |
|
![](./Soundblock-Double-Glazed-Windows-Sealing-Sydney-NSW.jpg) |
Many people have the impression that all silicone gels on the market are the same, but we have found that their properties and, therefore, suitability varies dramatically. Generally, the descriptions of silicone offer little information as to the correct grade and type for a given application, and because of performance variability, there is no one type of silicone sealant that should be used for everything. Using the incorrect silicone or improper use may cause joint failure, contamination of surfaces because of poor application, excessive movement in the sealed joint.

Climate Control |
|
![](./Thermally-Insulated-Windows-Climate-Control-Sydney-NSW.jpg) |
The power of the sun is generally underestimated. In one home, we measured 7kW of solar energy per hour on a sunny day in January, which is enough to some of your home appliances including air conditioners and heaters. This means that the same amount of energy is heating your home as you are using on an appliance to cool it! Upto 40% of heat or cold, depending on the season, can be escaping your home through badly insulated windows. Would you buy an appliance if you were told it could only operate at 60% capacity? And yet if your windows and doors have an inadequate u value score, you could be undermining your efforts to cool/ heat your home. Double Glazed Windows and Doors offer full control of your surroundings through a tight weather seal to insulate your home and make it energy efficient.
