Energy Efficient Glass


Enjoying big windows and great views while staying cool in summer and warm in winter is what most Australians crave in their built environment – and this s exactly what ENERGY EFFICIENT GLASS can offer.

Going GREEN and having energy efficient windows in homes and offices is quickly becoming a must-have. With energy costs reaching new heights and sustainability an important factor in construction, ORIGIN OZ Energy Efficient Glass is an exciting product which allows buildings to maintain comfortable temperature levels with minimal or no help from air conditioning systems.

Nearly 15-20% of all home energy is lost via windows and doors- energy efficient glass is fast becoming a priority as every unit of energy lost adds to the operational costs and environmental impact of a building.

Origin OZ manufactures both Solar Control and Low-E Glass for you to increase your building’s energy efficiency while staying GREEN and saving money on ongoing energy costs.


  • Reduced operating cost by consuming less energy to maintain building’s ideal temperature
  • Natural light coming in though the energy efficient glass is more comfortable than manufactured lights. Natural light costs nothing!
  • Reduced energy emissions = less pollution. Improved environment for building occupants
  • Public and CSR (Corporate Social Responsibility) reputation gain for being GREEN
  • Increase in building’s market value

Solar Control Glass

Clear glass provides high light transmission and visibility whilst reducing energy expenditure by up to 30%. By body-tinting glass with solar films this product provides both decorative colour and energy management by reducing solar heat gain, while retaining good daylight transmission and low reflectivity. Available in colours such as grey, bronze, green and blue, SOLAR CONTROL allows glass to absorb a portion of the solar heat as well as provide reductions in UV light exposure.

Solar control can also be achieved by applying solar control coatings onto clear glass or body-tinted glass during manufacture. These coatings are spectrally selective and work efficiently to reflect infrared solar radiation. These types of glass products can significantly reduce the solar heat gain of a buildings façade, therefore minimising air-conditioning requirements and the ensuing energy costs of a building.

By opting to install Solar Control Glass clients can expect to enjoy the associated benefits this product offers, such as:

  • 50% more energy efficient than a standard glazed glass
  • Up to 75% Solar reflection
  • Up to 40$ Glare reduction
  • Reduced external noise

Technical Specification

ORIGIN OZ Low-E coated glass products combine solar control with low emissivity performance in a single product.

Glass with a Low-E coating can reflect radiant infrared energy (heat), thus tending to keep radiant heat on the same side of the glass from which it originated while still letting visible light pass. This often results in more energy efficient windows as radiant heat originating from indoors in winter is reflected back inside, while infrared heat radiation from the sun during summer is reflected away, thus keeping it cooler inside.

There are two types of Low-E coatings available: ‘hard-coat’ or pyrolytic and ‘soft-coat’ or sputtered. Hard-coat glass is manufactured using the Atmospheric Pressure Chemical Vapour Deposition (APCVD) method of applying a doped tin composition to the surface of glass sheets as they are being manufactured in the hot tin bath of our glass float plant.


Hard-coat glass is considered a low to medium performance coating since the emissivity is greater (about 10 times) compared to the sputtered coating. The advantage of hard-coat glass is that it does not scratch easily and does not require special handling in the IGU assembly process in order to maintain the surface’s coating integrity.

Hard-coat Low-E glass can be used monolithically, toughened or laminated. However, most of the high performance soft-coat Low-E glass products are best used as part of insulating glass units (double glazing).


Soft-coat, or Magnetron Sputtering Vacuum Deposition (MSVD), is the other technology used to manufacture Low-E glass. In MSVD, sputter coated Low-E glass offers much better performance when compared to hard coat glass.

The sputtered coating however has a limited shelf life and may require special handling and storage for both the manufacturing process and IGU fabrication. Choosing a high performance Low-E glass over a hard-coat glass improves thermal performance of the IGU by about 13%.

ORIGIN OZ offers a complete selection of hard-coat and soft-coat Low-e glass products to suit your specific requirements in residential or commercial applications.

Our automatic glass processing equipment from cutting, handling, glass processing are fully equipped with the latest technologies to handle and process soft coat (sputter coated) as well as hard coat low-e glass.
