Replacement Windows Cut Heating and Cooling Costs

Many windows, especially older windows, transfer heat, allowing it to escape from one’s home during the winter months and enter the home in the summer. As a result, occupants incur higher heating and cooling bills by adjusting the thermostat to maintain a comfortable temperature.

For about 30 years, builders in the United States and Europe have been installing windows made with uPVC frames. Unplasticised PVC, also known as vinyl, is nonconductive. It does not transfer heat. This type of frame, especially when used with double or triple-glazed glass, significantly decreases the amount of heat or cold passing through windows and thereby helps to lower energy bills.

This quality is one of the many reasons why custom made uPVC windows in Melbourne are becoming increasingly popular. The most frequently used windows in the U.S. and Europe, uPVC windows and doors are relatively new to Australia. Today, there are many manufacturers making these versatile and efficient frames in a wide range of products.


UPVC frames are used to make a variety of windows and doors, including sliding and French doors, as well as casement, bi-fold, tilt, and sliding windows. The material is available in many colour options from plain to metallic to a wood-look finish.

The uPVC frame is also paired with several different types of glass. It can be used with single, double, or triple-glazed glass to create windows in any number of shapes. With the choice of round or half-round windows, arched, octagon, oval, bay, bow, and more, the homeowner and builder can design a truly unique look.

Double-glazed windows are the most common because they reduce draughts and provide an insulated barrier from the weather outside. Replacing one’s older windows with new uPVC double-glazed windows can drastically cut energy use, which also helps the environment by reducing greenhouse emissions.

Another popular option is the tilt and turn window, which can be opened and tilted for easier cleaning and turned to offer cross ventilation when the occupants of the home prefer a fresh breeze.


In addition to lower energy bills and customised options, the uPVC window offers many other benefits, some of which are listed below.

  • Durable
  • Low maintenance
  • Withstand extreme temperatures and weather
  • Flame retardant
  • UV resistant
  • High security
  • Recyclable

UPVC is durable and long lasting. It is resistant to rot and corrosion and will not rust or fade. As a result, it is very low maintenance and does not need to be painted or sealed regularly.

UPVC frames are available with several multi-locking systems, so they can be locked at multiple points around the frame and sash.

UPVC windows have been known to last for as long as 25 years or more, and the uPVC material can be recycled up to 10 times, providing another eco-friendly benefit compared to other materials.


Although uPVC windows are fairly new to Australia, one can feel confident in installing them. The material has been accredited by the Australian Industry Code of Practice to be used in doors and windows, meaning that it has been tested and confirmed to withstand various conditions. UPVC windows are also rated under the Window Energy Rating System among the highest performing windows.

The many benefits of uPVC windows make them an outstanding and increasingly popular choice for homeowners.
