Aluminium Vs UPVC Windows/Doors

Windows and doors are vital components of your home, impacting its overall appearance, functionality, and energy efficiency. When it comes to choosing the right material for these fixtures, two common options are aluminium and UPVC (Unplasticized Polyvinyl Chloride).

In this extensive blog, we'll delve into a detailed comparison of these materials and provide practical insights to help you make an informed decision about which one to use in your home.

Introduction to Aluminium and uPVC

Aluminium: Aluminium is a lightweight yet sturdy metal known for its durability and versatility. It is often used in construction, including windows and doors. Aluminium frames are admired for their sleek, modern aesthetics and robust build.

UPVC: UPVC, on the other hand, is a type of plastic known for its strength and resistance to environmental factors. UPVC frames are favored for their low maintenance requirements and energy-efficient properties.

Aluminium is a lightweight and strong metal that is commonly used in construction and manufacturing. Aluminium windows and doors are known for their durability, resistance to corrosion and rust, and low maintenance requirements. They are also available in a wide variety of styles to suit any home décor.

Pros

Durability: Aluminium is incredibly strong and can withstand even the harshest weather conditions.

Corrosion Resistance: Unlike some metals, aluminium is highly resistant to corrosion and rust, making it a good choice for coastal areas or other climates with harsh weather conditions.

Low Maintenance: Aluminium windows and doors require very little maintenance, just an occasional wipe with a damp cloth to keep them clean.

Energy Efficiency: Aluminium windows and doors can be made with thermal breaks, which help to improve energy efficiency and reduce heating and cooling costs.

Recyclable: Aluminium is a recyclable material, which can help to reduce your environmental impact.

Modern Appearance: Aluminum has a sleek, modern look that suits contemporary designs.

Cons

Heat Transfer: Aluminium can conduct heat and cold, which can make your home less energy efficient.

Soundproof: Aluminum sometimes cannot offer the same level of noise insulation as uPVC, which effectively reduces external sounds.

uPVC Windows and Doors

uPVC, or unplasticized polyvinyl chloride, is a type of plastic that is known for its affordability, durability, and low maintenance. uPVC windows and doors are a popular choice for homeowners who are looking for a cost-effective option that is easy to care for.

Pros

Insulation: uPVC has good insulation properties, helping with energy efficiency.

Soundproof: uPVC can provide good noise insulation, reducing external sounds.

Cons

Style: uPVC windows and doors are not as stylish as aluminium options and may not complement the architecture of all homes.

Scratches and Dents: uPVC can be susceptible to scratches and dents, especially if it is not handled with care.

UV Rays: uPVC may yellow or become brittle over time when exposed to UV rays, making it less suitable for climates with strong sunlight.

Limited Color options: uPVC, compared to aluminum, offers a more limited range of color options. While it is available in various colors and finishes, the selection may not be as extensive as what is possible with aluminum

Additional Considerations

In addition to the pros and cons of each material, there are a few other factors to consider when choosing between aluminium and uPVC windows and doors:

• Security: Both aluminium and uPVC windows and doors can be made with security features, such as laminated glass and reinforced frames. However, aluminium may be considered more secure overall due to its strength and rigidity.

• Safety: uPVC (unplasticized polyvinyl chloride) is a thermoplastic polymer that is more flammable than aluminum. This means that it will ignite more easily and burn more rapidly than aluminum. When uPVC is exposed to heat, it can decompose and release flammable gases, such as hydrogen chloride. These gases can ignite and cause a fire to spread quickly. 

Aluminum, on the other hand, is a non-combustible metal that will not ignite or burn.

Ignition temperature of uPVC is 170°C (338°F)

and ignition temperature of aluminium is 660°C (1220°F)

In addition to its flammability, uPVC can also produce toxic fumes when it burns. These fumes can be dangerous if inhaled, and they can also contribute to the spread of a fire. Aluminum, on the other hand, does not produce toxic fumes when it burns.

As a result of its flammability and toxicity, uPVC is not typically used in applications where there is a high risk of fire. Aluminum, on the other hand, is a commonly used material in fire-resistant applications, such as construction and fire suppression systems.

Overall, uPVC is a flammable material that can be dangerous in fire situations. Aluminum, on the other hand, is a non-combustible material that is safe in fire situations.

• Climate: If you live in a harsh climate, such as a coastal area or a region with extreme temperatures, aluminium may be a better choice due to its superior resistance to corrosion and heat transfer.

• Scrap Value:  When you change your windows, aluminum ones can still be sold for scrap, providing good value, unlike UPVC. So, in addition to enhancing your home's appearance, aluminum windows retain some value – a smart choice when you decide to upgrade.

• Budget: Set a budget before you start shopping and compare prices from different suppliers. Aluminium is generally less expensive than uPVC, but the cost may vary depending on the size, style, and features of the windows and doors.

Conclusion

Both aluminum and uPVC windows and doors provide a range of advantages, contributing to enhanced energy efficiency, security, and the overall aesthetic appeal of your home. The most suitable material for you will be determined by your specific requirements, preferences, budget, and the factors mentioned above.
