Double Glazing

Double Glazing

Double glazing has been the standard window in many parts of Europe for more than 20 years. In Australia it is relatively a new concept. Many are catching on to the many benefits of double glazing. First and foremost its cost saving in maintaining internal climatic control. Double glazing was first used in commercial buildings and now its becoming the new trend for homes. Now that the cost of energy is estimated to increase by as much as 20% over the next 12 months its a huge advantage to have high performance window systems installed or incorporated into your construction plans.

EcoWindowSystem is backed by over 20 years of research, design and engineering so you can be guaranteed of the best high performance window systems in Australia.

Our window systems have high quality efficient glass that reflect heat from the sun, cushion outside noise and prevent ideal inside temperature from escaping. EcoWindowSystem offers high performance double glazed systems that will maintain a comfortable environment in your home all year round.

Glazing has a major impact on the energy efficiency of your building. This means it has great cost saving potential. It will ensure your home is more efficient when it comes to keeping your home cooler in summer and warmer in winter.

Standard Australian window systems do not provide adequate insulation and standard glass can absorb and intensify heat from the sun in summer making your home hotter plus heat in winter can escape. Our energy efficient high performance window systems will significantly reduce the cost of energy required to cool or heat your home, even in the most challenging environments.

With the energy prices heading higher and higher it makes absolute sense to invest in our high performance window systems. Our windows will also improve the marketability of your property in years to come. Our window systems are distinctly designed to provide the highest thermal and acoutstic insulation levels available in Australia. Installing.

Energy Efficient Windows

Energy Efficient Windows for different seasons and climates

Cool or Cold

The priority in a cold or cooler climate is to retain heat in the home and maximise the use of ‘free’ solar energy in winter. Heat transfer takes three forms: radiant heat transfer, conducted heat transfer and heat transfer by infiltration of outside air.

In a cool climate the best results are obtained from windows that insulate well (low U-value) and admit plenty of free solar energy (high solar heat gain coefficient). In a cold region double glazed systems .


The priority in a mixed climate is to keep heat out of the home, except during a relatively mild winter season, when ‘free’ solar heat gain and retention of warmth in the house become important. Heat gain or loss takes three forms: radiant heat transfer, conductive heat transfer and heat transfer via air infiltration. Ideally, mixed climates call for strong solar control on east and west windows, but deliberate use of free sunlight admitted by northerly windows.

In a mixed climate (temperate) the best results are obtained from windows that insulate well (low U-value), admit plenty of free solar energy (high solar heat gain coefficient) on the north during cooler months, but limit solar heat gain from the east and west (low solar heat gain coefficient). Ideally, northerly windows should be protected by double glazed systems as this will provide protection from summertime heat and glare while still allowing the warmth from the sun in winter.

Hot or Warm

The priority in a warm climate is to keep unwanted heat out of the home. In order of decreasing importance, unwanted heat gain takes three forms: radiant heat gain, conducted heat gain and infiltration of hot outside air.

In a warm climate (tropical, subtropical or hot arid) the best results are obtained from windows that limit solar heat gain on all orientations (low solar heat gain coefficient). Good insulation (a low U-value) is highly beneficial, especially if the home is air-conditioned.

Thermal Insulation

Thermal Insulation

The importance of thermal insulation indoors is very important when it comes to energy efficiency. About 35% of energy can be lost through non-efficient windows. Our window technology has window and thermal break aluminum construction with high thermal insulation performance. The benchmark obtained is lower to ensure a higher insulation rating, the lower the value the higher the insulation.

Acoustic Insulation

Acoustic Insulation

Doors and Windows are the main responsible for the noise coming from outside the House. This type of discomfort can be very annoying and harmful to your health. It is right therefore pay great attention in choosing the profile of the glass and frame to install. The soundproofing of a stained-glass window indicates the removal of noise in Db; therefore stained with the highest coefficient are better. The use of glass in glass replacement simple discrete results, gives good results can be obtained through the use of specific products (laminated glass for noise abatement).

Quality Seals

Quality Seals

Windows are an important element of the building envelope and must be installed to withstand rain and wind loads, to achieve ideal results the choice of high quality windows ensures air tightness. Same with doors, the air tightness of doors is identified by 5 different classes; the class 0 for Windows not tested, classes from 1 to 4. Class 4 is the best choice.

Energy Efficient Glass

Energy Efficient Glass

The solar control glass consists of different types; traditional, colored or mirror, but its most interesting aspect is that it includes layers of special materials, which have the characteristic transparency to convert sunlight, but reject heat. The solar control is the result of the superficial deposits that are applied on one side of the glass, which can be obtained through a pyrolytic process.

The first process – a thin film of chemical substances, composed of multiple layers of metallic alloys, is applied to the glass sheets with high temperature, sprayed directly on the surface of the tape during glass production.

The second process – however, is always applied on glass plate, a thin film of chemical substances composed of multiple layers of metallic alloys, but in a vacuum environment.

The special metal coating ensures that in winter months the glass holds heat and in summer months the glass reflects the heat.

Unlike standard window glass, EcoWindowSystem’s double glazed glass systems ensures thermal and acoustic insulation, conserving energy thus reducing the cost to stay comfortable all year round.
