uPVC windows have the frames made from the material named uPVC which is the short term for unplasticized polyvinyl chloride. In the manufacturing process, the uPVC is heated to the point that it becomes liquid and then injected into the frame moulds.
Windows made from uPVC have the added benefit of being cost-accessible and ecologically-friendly. This is because the uPVC material can be reused for up to four times until it starts to loose its strength.
uPVC windows costs[edit | edit source]
The cost of uPVC windows varies substantially and depends on the style and type of window chosen. Various important factors should be taken into consideration including:
- Larger uPVC windows are more expensive than smaller windows
- Standard shapes are cheaper than non-standard shapes
- Handles and various types of hardware
- Air vents, window sills, and grids
Advantages of uPVC windows[edit | edit source]
There are many advantages to choosing uPVC windows:
- Their cost is relatively low compared to the cost for window frames made from other materials.
- They are also low maintenance as they do not need to be repainted. Additionally, they do not flake, rust, fade or rot.
- uPVC windows most often can provide the best heat and energy insulation.
- They are also water proof, in comparison to wood frames which are not.
- Aluminium frames can suffer from rust or can pick, but uPVC windows are more durable and do not have this problem.
- They also confer security as they are difficult to break or be damaged.

- Because they are made from plastic, some people consider that uPVC windows are not as visually appealing as aluminium or timber windows.
- They can sash and sag due to their light structure.
