Comparing PVC, uPVC, and Aluminium Windows: A Guide
When it comes to choosing windows for your home, there are several material options available, including PVC, uPVC, and aluminium. This article provides a comparison guide to help you make an informed decision based on your specific needs.
PVC and uPVC Windows:
The main difference between PVC and uPVC is that PVC contains plasticizers, such as BPA and phthalates, which make the material more flexible On the other hand, uPVC is unplasticized and therefore stronger and considered a rigid plastic.
PVC is not typically used for window frames, and some manufacturers may use "PVC" to refer to their uPVC windows uPVC is preferred for window frames because it is weather-resistant and does not decay. uPVC is also commonly used for door frames and conservatories.
While PVC is designed to be softer and more flexible than many other plastics, it is less durable than uPVC However, both materials are resistant to sunlight, oxidation, and a range of chemicals
uPVC windows are an excellent choice for new double or triple glazing as they are energy-efficient and easy to maintain and clean They are naturally warm, and the multi-chambered frames provide great insulation, which helps keep energy bills down during the winter They are also more thermally efficient than aluminium windows.
Aluminium windows, however, are stronger than uPVC and have a sleeker profile and larger glass surface area, making them popular in commercial and public buildings They are also environmentally friendly as the material is recyclable, and they offer greater design flexibility with a wide range of colors available
When considering the cost of the windows, the difference can be significant, with aluminium windows typically more expensive than PVC. The lifespan of PVC windows is around 15-20 years, while uPVC can last up to 50 years due to its greater resistance to corrosion and sunlight
In summary, all materials have their advantages and disadvantages, and the ultimate decision should be based on your specific needs and budget. PVC and uPVC windows are a good choice for energy efficiency and ease of maintenance, while aluminium windows offer greater strength and design
