Aluminium tends to be stronger than uPVC. That means that aluminium windows can have a slimmer appearance, and a larger glass surface area due to the strength of the frames. For this reason they're very popular with commercial and public buildings like schools, offices and government buildings.
Aluminium is supremely strong and durable and is highly resistant to corrosion, capable of standing up to the outside elements. While PVC windows may require periodic replacement, you can rest assured that aluminium systems will keep on working, providing style and performance without compromise.
Poor insulator: Aluminum doesn't hold in heat as well as other materials. However, weather-stripping and thermal treatment can make this less of an issue. Condensation: Moisture or even frost can form inside aluminum-frame windows, leading to problems.
If you're after a sleek look to your home, aluminium frames offer slimline frames. Thanks to the strength of the aluminium alloy used, narrower frames can be made meaning more of the window is made up of glass. uPVC frames, on the other hand, are thicker and chunkier.

Durability. Aluminium windows have can last up to 30 years. This is because, aluminium is considerably more resistant to the outside elements compared to other frames, making them less likely to warp or rot as a result. Aluminium also has a high strength-to-weight ratio, making them harder to dent.

Simply put, there is no difference between the UPVC and PVCu because the two abbreviations represent the same material being Un-plasticised Poly Vinyl Chloride. Installers use UPVC in the promotion windows, doors and other home improvement products but it is also referred to as PVCu.
Casement windows are considered better than double-hung windows at keeping out drafts since the window seal is generally quite tight. Casement windows are good when you want to "scoop" cooling outside air into the house.
The doors and windows made with uPvc [raw material is cheap @ Rs 95/KG where as aluminium is costly Rs 225/KG ] are bulky and the shutter movement is not as easy as it should be unlike aluminium shutters which run smoothly if high quality runners are used.
Nevertheless, uPVC windows and doors are completely resistant to strong tropical rains. The latest technology used by Encraft complying Waterproof Standards BS EN 1027 & BS EN 12208 through its Class 9A (Casement series) & class 4A (Slider series) acts as a shield of protection (waterproof) during monsoons.
