Window Glazing and Frame Material

 

Uncoated single-glazed windows transmit a huge amount of heat into and out of your home. They are the weak link in the building envelope. Like most windows in Australia, yours are probably single-glazed.

By upgrading your windows from single to double-glazed, you will make your home healthier and more comfortable in the cold and warm months, and significantly reduce your energy costs. Quality window systems will also increase your home’s security against intruders.

 

Why Double Glazing?

  • A double-glazed window will reduce heat conduction by over 50% compared to single glazed
  • With double-glazed windows, you will reduce your reliance on artificial heating and cooling
  • Upgrading your windows will improve comfort and health as the thermal resistance of the windows preserves internal temperatures
  • Double-glazed windows reduce ultraviolet radiation, which contributes to skin cell damage and fading carpets and furniture
  • Upgrading your windows will reduce internal and external noise, meaning a quieter, more comfortable home
  • A result of warm, humid air meeting a cold pane of glass is condensation. Double-glazed windows produce less condensation than single-glazed windows. This prevents mould growth, which is a major health risk and can devaluate your property.

 

How does it work?

A double-glazed window has two panes of glass with a sealed air gap between them. The panes are spaced with metal or plastic, often sandwiched between thin rubber. The panes include a desiccant, which prevents condensation between the panes. The gap can be filled with a gas, such as argon, instead of air. The panes can be plain glass, or treated with tinted, reflective, toned or low-emissivity coatings, to improve effectiveness even more.

 

Window Frame Material

The type of window frames you use also plays a big role in determining the cost of heating and cooling your home, and how well your windows keep the weather out. Timber frames and uPVC timber frames are the highest performing, best insulating window frames available. Both will keep the transder of unwanted heat and cold between inside and outside to a minimum.

uPVC

The benefits of uPVC frames include:

  • The best acoustic properties – no more noisy neighbour problems
  • Best thermal properties – nothing stops heat loss like uPVC
  • High security – multipoint locking systems available
  • Easy maintenance and long life
  • Available in many colours, frame types, and sizes

Timber

Timber frames are comparable to uPVC frames:

  • Very strong acoustic properties, keeping the sound out
  • Very strong thermal properties
  • Able to be manufactured in much larger dimension than uPVC
  • Available in many colours, frame shapes and sizes

Aluminium

Aluminium is the strongest and most durable material and is easy to clean and maintain. Aluminium frames are most commonly used in commercial and retail properties, but are well suited to residential as well. To prevent heat transfer, aluminium frames are thermally broken.
