What is Double Glazing?

Double glazed windows and doors are made from two panes of glass that are separated by a layer of air or gas and then sealed. The use of two panes of glass dramatically reduces noise and heat transmission. 

The use of a gas, most often argon, is preferable between the layers of glass as it is considered to be a superior insulator than those with just a sealed pocket of air. For optimum thermal performance, double glazing should have a space of 16 to 20mm between the panes. 

In a standard single glazed window, both heat and noise are easily transferred. In summer, sunlight heats up your house and in winter, heat escapes from inside your home to the outside. You pay more for heating and cooling costs and all year-round, noise can easily pass through the window. Visit our ‘Why Double Glazing’ page for more information on the benefits of using double glazing. 

What are Thermally Broken Aluminium Frames?

Thermally Broken Aluminium frames are made from premium grade aluminium, with the internal and external surfaces separated by a polyamide (plastic) thermal break, dramatically reducing the transfer of heat and cold. This surpasses the standard single glazed aluminium frames used in Australian products, which conduct heat and cold readily, greatly reducing their effectiveness in maintaining a comfortable living space.

What is uPVC Double Glazing?

Poly Vinyl Chloride, which we know as every day ‘PVC’ is softened to be used in the manufacture of products such as sport bags and fake leather. It is the use of this material which has made us familiar with the abbreviation ‘PVC’. For windows, the ‘PVC’ part stands for Polyvinyl Chloride and the ‘U’ stands for un-plasticised. Additionally, for the Australian climate, titanium is added to the material so as to withstand our extreme heat.

The basic material properties of uPVC make it ideal for window and door application:

  • uPVC does not rot or biologically decompose.
  • uPVC is resistant to weathering with low-maintenance requirements.
  • uPVC is tough on impact.
  • uPVC retains its shape within normal climatic temperatures.
  • uPVC can be reshaped at very high temperature and can therefore be recycled.

To combat the harsh Australian climate, Titanium is also added to withstand the extreme heat. uPVC frames are the highest quality frames available on the market today. They are the gold standard window and door frame in advanced markets like North America and Europe. Visit our product pages to download our brochures or to learn more about uPVC double glazed windows & uPVC double glazed doors.

What are the benefits of uPVC frames?

uPVC is extremely durable. Unlike steel or aluminium frames, uPVC versions don’t corrode or oxidise, and they won’t rot like wooden frames. uPVC is virtually maintenance free – it won’t need re-painting. With just a quick wipe clean every now and then, they will maintain their ‘straight-from-the-showroom’ appearance.
