What are uPVC windows?

uPVC stands for un-plasticized polyvinyl chloride. uPVC is formed when there are no plasticisers added to regular PVC, making it rigid and strong. Although it is new to Australia, it has been a popular choice in Europe and America for a long time because of its durability and low maintenance.

uPVC has extensive uses in the building industry as it is a low maintenance material for both the commercial and residential sectors. It’s most commonly used for the frames of windows.

Properties of uPVC

uPVC Aesthetics

uPVC profiles will keep their colour even under exposure to extreme temperatures, weathering or UV exposure, making them ideal for the Australian climate. uPVC is very easy to customise with a range of colours, finishes and shapes available to suit any design requirements.

Energy resistant uPVC windows

Insulation is the most critical property of uPVC. It’s incredibly efficient at ensuring that the inside heat does not escape to the outside. When combined with double glazed glass, you can reduce heating requirements by up to 80%.

Noise insulation of uPVC windows

uPVC window frames have very tight seals making them excellent at providing sound insulation to your home.

uPVC windows are low maintenance

It’s so easy to install, repair and remove uPVC windows without causing any damage to other structures of your building. To clean the profiles, you simply use a cloth with mild liquid detergent (diluted dishwashing liquid) to keep them looking great.

Durability, security, and resistance to weather.

Although uPVC windows are lightweight, they are also very strong, making it hard for intruders to break in.  It’s also resistant to corrosion and inclement weather. uPVC windows can withstand the extremes of heat, cold, wind, rain and snow without corroding, peeling, chipping or flaking.

How to make uPVC windows

In a nutshell, uPVC window frames are constructed from multiple pieces that are joined together to form the shape of the window. Patterns are created by forcing molten PVC through a precision die and cool the material to cut it to the desired length almost immediately. The appearance of the profile will depend on the characteristics of the pattern and tooling done.

Once you have the profiles ready, you can then fabricate the windows from the pieces of the pattern which are cut already to different sizes. Either heat fusion or T-joint connectors are used to join the profiles together. Steel sections can also be used as reinforcements for extra strength if required.

uPVC additives and stabilisers

Polyvinyl chloride is the basis for uPVC, however, there are some additives and stabilisers required for the profiles to be fit for use in your Perth home or office. There are specific heat and UV stabilisers that are central to the manufacture of any uPVC windows.

The type of stabiliser needed is dependent on what is required for the final product. These stabilisers are made up of metallic components and other organic compounds. There are varieties of metal stabilisers used for different window applications.

UPVC window maintenance and repair

There are two types of window repairs:

Surface repairs

You can complete surface repairs in the case of scratches and minor issues that affect the appearance of the window. Other types of surface repairs are required if there are holes and knocks on the structure of the window. Surface repairs are quite simple to complete and don’t require much time.

Functional repair

A functional repair is required when there is damage evident to the hardware such as hinges and handles. The hardware is simply replaced when a functional repair is necessary. This type of repair is also relatively easy as it is just a replacement.
