What are UPVC and Aluminium Windows?
Before we get into uPVC vs aluminium windows comparison, let’s quickly cover what these windows are made of.
- uPVC (Unplasticized Polyvinyl Chloride): It’s a type of plastic that’s rigid, durable, and doesn’t corrode. It’s been a favourite for modern homes due to its insulation qualities and low maintenance.
- Aluminium: This one’s a strong, lightweight metal. It’s known for its sleek look and high strength. Great for slim frames and large glass panels.
Both of these materials are miles ahead of traditional wooden windows when it comes to durability and upkeep. But they’re very different from each other in feel, look, and performance.
1. Appearance and Aesthetics
Let’s start with looks—because honestly, it matters.
Aluminium windows are the winners here if you want a clean, minimal, and ultra-modern look. The frames are slimmer, which means more glass and less metal. This makes the space feel open and airy.
uPVC windows, on the other hand, tend to look chunkier because the frames are thicker. But that doesn't mean they're ugly—many brands now offer sleek designs and finishes, including wood-like textures, which can suit both modern and traditional homes.
Verdict:
- Choose aluminium if you love minimal design.
- Go with uPVC if you want variety in colour and texture or are aiming for a more classic look.
2. Thermal Performance
This one's about how well your windows keep out heat (or cold) and help maintain a stable temperature indoors.
When doing uPVC vs aluminium windows comparison, uPVC windows are known for excellent insulation. They don’t conduct heat or cold, which makes them ideal for places with extreme summers or winters. You’ll often feel a noticeable difference in room temperature if you switch from metal to uPVC.
Aluminium windows, by nature, conduct heat. So, unless they come with a thermal break (a special insulating layer between the inside and outside frame), they may let in more heat or cold. Good brands do offer thermal break options, but they’ll cost more.
Verdict:
- For better thermal performance, uPVC is generally the better choice.
- If you go with aluminium, make sure it’s thermally broken.
3. Durability and Lifespan
Both uPVC and aluminium are long-lasting, but in different ways.
Aluminium windows are incredibly strong and resistant to corrosion, especially if you live in coastal areas. The frames don’t warp, fade, or crack, and they can easily last over 40 years with minimal wear.
uPVC windows are also durable but slightly more sensitive to extreme conditions. In very hot or very cold regions, they may become brittle over time. Still, they can last around 25–30 years if maintained properly.
Verdict:
- Aluminium wins in terms of sheer strength and long-term resilience.
- uPVC is durable too, but slightly less so in extreme climates.
4. Maintenance Difference
In, uPVC vs aluminium windows comparison, here’s where uPVC gets full marks.
uPVC windows are practically maintenance-free. They don’t need repainting, don’t rust, and just need an occasional wipe with a damp cloth.
Aluminium windows aren’t high maintenance either, but over time, the finish may wear off—especially if you live in a place with salty air. Anodised or powder-coated versions last longer, but you may still need to repaint or polish after many years.
Verdict:
- uPVC is easier to maintain overall.
- Aluminium may need more care long-term depending on the coating and your environment.
5. Strength and Security
If your top concern is safety and strength, aluminium might be more your style.
Aluminium windows are stronger by design, which makes them better suited for large window panes, sliding doors, or commercial buildings. They can handle bigger glass panels and resist impact better than uPVC.
uPVC windows are secure too, especially if paired with multi-point locking systems. But they’re not as robust as aluminium, especially in very large frames.
Verdict:
- For strength and security, aluminium has the upper hand.
- uPVC works well for smaller windows and standard residential use.
6. Sound Insulation
In uPVC vs aluminium windows comparison, this one’s important, especially in cities with traffic noise, barking dogs, or construction sounds.
uPVC windows tend to do a better job at keeping out noise. The material, combined with good quality double glazing, can block out a surprising amount of sound.
Aluminium windows can be soundproof too, but because the material is more conductive and less dense than uPVC, they usually need better glazing and sealing to reach the same level of sound insulation.
Verdict:
- uPVC is generally better for sound insulation.
- Aluminium can match it, but will likely cost more.
7. Environment and Sustainability
If eco-friendliness is a concern, aluminium is more recyclable than uPVC. Aluminium frames can be melted and reused multiple times with minimal loss in quality.
uPVC is recyclable too, but the process is more complex and not as widely available in India.
Verdict:
- Aluminium is more eco-friendly from a recycling point of view.
- uPVC still performs well but isn’t the greenest option out there.
Pricing in India
In general, uPVC windows are more budget-friendly in India. Depending on the design and brand, they usually cost between ₹400–₹900 per sq. ft., including installation.
Aluminium windows tend to be pricier. Standard versions start from ₹700–₹1,200 per sq. ft., while high-end thermally broken frames can go up to ₹2,000 or more.
Also, keep in mind: uPVC may help you save on energy bills because of better thermal performance. Aluminium might cost more upfront, but it lasts longer, which can even things out in the long run.
So, in the uPVC vs aluminium windows comparison, you should check carefully:
- On a tight budget? Go with uPVC.
Want premium, long-term durability? Aluminium might be worth the investment.
Final Thoughts: Which One Should You Pick?
There’s no one-size-fits-all answer in the uPVC vs aluminium windows comparison—it really depends on what you care about most.
Go with uPVC if:
- You want better insulation
- You’re on a budget
- You prefer low maintenance and solid soundproofing
Choose Aluminium if:
- You love modern, slim designs
- You need strong frames for large glass panels
- You want windows that last decades with minimal fuss
Think about your location, weather, and budget. And don’t forget: the right installation matters as much as the material itself.
Whichever option you choose, make sure you go with a trusted brand and experienced installer.

FAQs
- Which is more energy-efficient: uPVC or aluminium windows?
uPVC windows are more energy-efficient because they don’t let heat in or out easily. This helps keep your home cooler in summer and warmer in winter. Aluminium can be energy-efficient too, but only if it has a special thermal break. - Are aluminium windows better for large glass panels?
Yes, aluminium is stronger than uPVC, which makes it better for big glass areas like sliding doors or full-length windows. The frames can be thinner and still hold the weight well. That’s why aluminium is often used in modern designs and commercial buildings. - Do uPVC windows fade or crack in the sun?
uPVC windows are built to handle sun and rain, but in very hot climates, they can become brittle over time. Good-quality uPVC lasts longer and doesn’t fade easily. Regular cleaning and choosing a trusted brand can help them stay in good shape for years.
