Both commercial and residential buildings have wall openings to allow fresh air and light to come inside. Aluminium is the most common material used in commercial buildings across India, but for residential buildings, options include wood, steel, UPVC, and Aluminium. When it comes to comparing UPVC vs aluminium windows, both materials have their advantages and drawbacks. Wood has long been a preferred option for residential windows, but its share is declining due to high costs and the difficulty in finding skilled carpenters. Steel has been popular because of its lower initial cost, but it is also seeing a decline due to quality and maintenance issues. As a result, the debate of aluminium vs UPVC windows has gained prominence, as both offer unique benefits for residential applications.
The two main materials today for residential windows are aluminium and UPVC windows, each with distinct characteristics. Aluminium has been used for many years in India, particularly for high-rise buildings, due to its strength and sleek aesthetics. However, UPVC windows and aluminium windows are becoming more popular in colder climates, where they are used in combination with double or triple glazing to offer superior insulation. UPVC windows, often referred to as vinyl windows, are known for their energy efficiency, which makes them an excellent choice for homes looking to improve thermal performance. On the other hand, aluminium windows are prized for their durability and ability to withstand harsh weather conditions, making them suitable for various climates across India.
In conclusion, understanding the differences between UPVC windows vs aluminium windows is crucial to making an informed decision for both residential and commercial applications. Whether you are comparing aluminium vs UPVC windows for their cost-effectiveness, energy efficiency, or longevity, it’s important to consider the specific needs of your building. While aluminium windows provide strength and modern appeal, UPVC and aluminium windows should be considered for their superior insulating properties, especially in areas that experience extreme weather.
Differences Between UPVC Windows and Aluminium Windows
The modern Aluminium windows are known as ‘System Windows’ which are tested for safety in extreme weather conditions. The comparison between System Aluminum windows and UPVC Windows is given below:
1.
Popularity:
It is estimated that aluminium windows have a share of over 50% in India, while UPVC windows may hold around 15-18% of the market. The difference between UPVC and aluminium windows often comes down to materials: aluminium, being a metal, is typically seen as more premium compared to UPVC, which is made from plastic (PVC). Aluminium windows stand out in premium buildings, especially due to their vibrant colours, while UPVC windows are mostly white, making it easier to distinguish between the two in upscale construction projects.
2.
Strength to face high winds:
UPVC windows vs aluminium windows comes into play when discussing strength against high winds. UPVC gets its structural strength through a steel reinforcement inside the window profile. The bigger the steel section, the stronger the window, but this results in bulkier windows that reduce the amount of light entering the space. Additionally, the corners of UPVC windows are weak due to welded joints, which makes them unsuitable for high-rise buildings or larger windows. In contrast, aluminium windows can be designed to withstand various wind pressures depending on the building’s location (e.g., sea fronts), with thicker sections offering greater resistance. Since aluminium corners are mechanically joined, transportation is easier compared to UPVC windows, which are welded and can’t be taken up a staircase.
3.
Durability & ease of usage:
When comparing the durability of UPVC vs aluminium windows, UPVC windows are more vulnerable to UV rays from the sun, which causes them to become brittle and yellow over time. This issue worsens if the supplier reduces TiO2 content in the material, which is hard to identify in new windows. Aluminium windows, however, are much more durable, with anodized and weather-resistant coatings that ensure no corrosion, especially in coastal areas. Aluminium windows also have a longer lifespan in tropical climates like India, as UV rays have little impact on them. The hardware in aluminium upvc windows is generally more corrosion-resistant, and the metal-to-metal lock fixing makes them more secure. Additionally, aluminium windows are easier to operate due to larger rollers, and features like door closures or child safety catches can be easily added.
4.
Design Freedom:
In terms of design freedom, aluminium windows are much preferred by architects because of their slim profile and versatile range of design options. Aluminium vs UPVC windows becomes clear when considering the variety of architectural styles that aluminium windows can cater to. They offer options that suit everything from budget-friendly to high-end designs, while also accounting for different weather conditions. On the other hand, the product range of UPVC windows is more limited, primarily due to the difficulty in fixing hardware and size restrictions. UPVC windows are better suited for small windows in regions like Europe, where they are used primarily for light and ventilation. However, as architecture in India moves toward bigger windows with higher ceiling heights and better integration with outdoor spaces, aluminium windows are more fitting.

Weather resistance:
The weather resistance of UPVC windows vs aluminium windows depends on the climate. UPVC has an advantage in very cold climates, as the plastic material helps prevent cold from entering the room. However, in warmer climates, the difference between UPVC and aluminium windows becomes less significant, as reflective glass plays a bigger role in blocking direct sunlight. Larger UPVC windows tend to deflect at the corners, compromising their weather resistance. Aluminium windows, on the other hand, are designed to perform better in tropical climates like India, where monsoon winds and coastal conditions are prevalent. Aluminium upvc windows designed with better gaskets and systems are more effective at preventing water, dust, and pollution ingress, and their soundproofing features eliminate issues like whistling in high-rise buildings.
6.
Stopping ingress of noise:
When it comes to noise reduction, the performance of aluminium vs UPVC windows largely depends on the sealing quality and the type of glass used. Aluminium windows use gaskets to reduce air gaps, whereas UPVC windows use wool piles that can compress over time, diminishing their effectiveness. Noise reduction is also heavily influenced by the type of glass used; laminated glass has superior noise-blocking properties compared to standard double-glazed glass. The highest levels of noise reduction are achieved with laminated double glass of unequal thickness, a feature available in both aluminium windows and UPVC windows.
7.
Colour choices:
UPVC windows are typically available in white, although wood finishes are an option, but at a higher cost. In contrast, aluminium windows come in a wide variety of colours, enhancing the exterior aesthetics of buildings and providing better harmony with interior design elements like curtains and carpets. The Texguard finish offered by brands like Tostem adds a unique sheen to aluminium sections, making them look superior to traditional powder coating finishes.
8.
Maintenance:
When comparing maintenance, aluminium vs UPVC windows is clear: UPVC windows—especially white ones—are harder to maintain and can show dirt and discoloration over time. Aluminium windows, particularly those with a Texguard finish, are much easier to clean and require minimal upkeep. The finish is durable enough to last a lifetime without the need for repainting, and the hardware remains rust-free, making the overall maintenance nearly zero for aluminium windows.
9.
Cost:
In terms of the cost difference between UPVC and aluminium windows, although UPVC windows may seem more affordable upfront, aluminium windows prove to be cheaper over the long run. This is especially true for high-quality UPVC windows with high TiO2 content that do not fade over time. Aluminium windows have a broader product range, accommodating various design and strength requirements. While luxury options and larger aluminium windows can be expensive due to the need for larger sections, aluminium windows are generally a more cost-effective choice when considering their durability and longer lifespan.
Conclusion
The market preference is quickly shifting in favor of aluminium windows due to their superior performance in all weather conditions. Architects prefer aluminium vs UPVC windows for their fit and finish, safety features, and ease of use, with minimal need for maintenance. The design freedom offered by aluminium windows and their slim profiles significantly enhance the aesthetics of modern buildings, making them the preferred choice over UPVC windows in many upscale projects.
