How are UPVC windows made?

UPVC windows are extremely high performance units, which are renowned for their fantastic durability, energy efficiency, security and versatility. As a result, they are widely used in both domestic and commercial properties alike.

But, how exactly are these windows made? (And what does UPVC actually mean?)

Below, we have shared a quick guide to the manufacture of UPVC windows, including how they are made, and the materials that they consist of.

 

What materials are UPVC windows made from?

UPVC windows are primarily made from the following materials:

• UPVC profiles – the framework of the window, which is made from UPVC.
• Glass panes – forming single, double or triple glazed units
• Sealants – sealing the joints between the profiles and panes
• Hardware – bespoke additions, such as handles, hinges and locks

 

How are UPVC windows made?

UPVC stands for Unplasticised Polyvinyl Chloride.

UPVC is made when vinyl chloride monomers go through a process called polymerisation. This type of PVC does not contain plasticisers (a type of additive, which makes PVC such a flexible material).

Instead, vinyl chloride is polymerised, which results in the creation of long chains of vinyl chloride molecules, also known as polyvinyl chloride (PVC).

The PVC is then combined with the required additives, before it is heated and moulded into the desired shape.

 

From there, the process of manufacturing a UPVC window is as follows:

• The UPVC is moulded into the chosen design of UPVC window profile.
• The window frames are cooled, cut to length and then joined.
• Usually, UPVC window profiles are hollow, as this allows for other elements to be added. This means that, at this stage, they can be fabricated to accommodate the required features.
• The glass panels are cut to the required size (more on this step below).
• The glass panels are inserted into the UPVC frame.
• The glass panels are securely sealed in place (either with sealants or gaskets)
• The window’s features are added and the hardware is attached. This can include reinforcement, joints and drainage channels, or hardware such as handles, hinges and locks.

UPVC is an extremely versatile material, and it is available in a huge range of different sizes, colours and design styles. So, following the process above, UPVC window manufacturers can work with their customers to create bespoke products that tick all their boxes.
