What Are Aluminium Windows?
Aluminium windows are built with strong, lightweight frames that can hold large glass panels without bending or warping. Because of their natural strength, they don’t need thick borders, which is why many modern homes use to get wider views and more daylight indoors.
The frames are usually powder-coated, giving them a smooth finish that can be customised in different colours. Aluminium is also highly resistant to rust, moisture, and harsh weather, so these windows can last for decades with minimal care. Whether in a luxury apartment, a coastal villa, or a commercial building, aluminium window designs combine durability with a clean, modern look.

The frames also resist moisture, so they won’t swell, rot, or rust. Available in different colours and finishes, uPVC windows suit both modern and traditional homes. They are a popular choice for homeowners who want an affordable, low-maintenance window option that still delivers on durability and energy efficiency.

Aluminium Windows vs uPVC: Cost Comparison
When comparing prices, the uPVC windows in India is usually 20–40% lower than aluminium windows for similar sizes and styles. This makes uPVC attractive for homeowners working within a fixed budget. Here are the cost differences of Aluminium windows & uPVC windows.

Which Windows are Stronger: Aluminium or uPVC?
When it comes to strength, aluminium clearly outperforms uPVC. In the aluminium vs uPVC comparison, aluminium frames have a much higher strength-to-weight ratio, which means they can support larger glass panels without the need for thick frames or extra reinforcement. This makes them the preferred choice for wide openings, tall windows, and modern designs, just like Tejjson’s vertical sliding aluminium windows, where stability and smooth movement are essential.
uPVC windows are still strong enough for standard residential sizes and offer good performance for everyday use. However, they are not ideal for oversized panels or areas with high wind pressure. Over time, uPVC can also lose some rigidity, especially in hot climates, while aluminium retains its shape and strength for decades.
If your priority is durability, stability, and the ability to create bigger, more open views, aluminium is the stronger and more reliable option.
