If you’re planning new windows, one of the first questions you’ll ask is:

Should I choose uPVC or aluminium — and which one costs more?

It sounds like a simple comparison. But in reality, most price comparisons in the market are misleading.

Why?
Because people often compare:

• Fabricated aluminium vs system uPVC
• Basic uPVC vs premium aluminium
• Single glazing vs double glazing

That’s not an apples-to-apples comparison.

This guide breaks down the real cost of uPVC vs aluminium windows in India for 2026, including:

• Price ranges
• What affects cost
• Lifecycle expenses
• Where each material makes sense

By the end, you’ll know what you’re actually paying for — and why.

Step 1: Understand the Types in the Market

Before comparing cost, understand the categories.

uPVC Windows

1. Fabricated uPVC windows
2. System uPVC windows

Aluminium Windows

1. Fabrication aluminium windows
2. System aluminium windows (engineered systems)

Most confusion happens because buyers compare:
fabrication aluminium with system uPVC
or
basic uPVC with premium aluminium

That creates misleading price conclusions.

Step 2: Typical Price Ranges in India (2026)

These are broad market ranges for standard configurations (indicative, not brand-specific).

Fabrication Aluminium Windows

Approx:
₹450 – ₹600 per sq.ft

Depends on:

• Section thickness
• Glass
• Basic hardware

Usually entry-level.

System Aluminium Windows

Approx:
₹1,200 – ₹2,500+ per sq.ft
(premium systems can go higher)

Includes:

• Engineered profiles
• Better hardware
• Precision sealing

Used in:

• Premium apartments
• Villas
• Large openings

Fabrication uPVC Windows

Approx:
₹400 – ₹550 per sq.ft

Basic systems:

• Thin profiles
• Basic hardware
• Limited reinforcement

Lower upfront cost but performance varies.

System uPVC Windows

Approx:
₹900 – ₹2,000+ per sq.ft

Depends on:

• Profile thickness
• Reinforcement
• Glass
• Hardware
• Installation

Premium system windows fall here.

Step 3: What Actually Affects Window Cost

Material alone doesn’t decide price.

1. Glass Specification

This can be 20–35% of window cost.

Options:

• Single glass
• Laminated
• Double glazing
• Low-E

Higher performance glass increases cost in both aluminium and uPVC.

2. Hardware

This can be 25–35% of window cost.

Quality hardware affects:

• Smoothness
• Security
• Lifespan

Multi-point locking and branded hardware increase cost but improve performance.

3. Profile Quality

Thicker profiles and reinforced systems cost more but last longer.

uPVC:

• Wall thickness
• Reinforcement
• Formulation

Aluminium:

• Section thickness
• Thermal break
• Finish

4. Installation

Installation is often ignored in cost comparisons.

Professional installation includes:

• Gap planning
• Anchoring
• Foam sealing
• Silicone sealing
• Alignment

System-driven installations, where installation is part of the overall window design (as followed in structured approaches like Ascendia), typically deliver more predictable long-term performance.

5. Size & Configuration

Larger windows:

• Need stronger reinforcement
• Use more glass
• Need heavier hardware

Costs rise accordingly.

6. Finish Options

For aluminium:

• Powder coating
• Anodising
• Wood finish

For uPVC:

• Laminations
• Colour profiles

Premium finishes increase cost in both.

Step 4: Lifecycle Cost — Not Just Initial Price

Initial price matters.
But long-term cost matters more.

Maintenance

uPVC:

• Minimal maintenance
• No repainting

Aluminium:

• Also low maintenance in system versions
• Hardware servicing may be required

Both are comparable when quality systems are used.

Energy Efficiency

Better sealing and glazing can reduce cooling load.
Energy savings depend more on system design than material alone.

Replacement Cycle

Low-quality systems may need early replacement.

Well-engineered system windows — whether uPVC or aluminium — can last decades.

Step 5: Where Aluminium Costs More

Aluminium may cost more when:

• Using slim premium systems
• Very large openings
• Minimalist façades
• Structural spans

High-end aluminium systems can be significantly more expensive.

Step 6: Where uPVC Costs More

uPVC costs increase when:

• Using premium profiles
• Laminated finishes
• Heavy-duty hardware
• Large shutters

System-grade uPVC is not always the cheapest option — and shouldn’t be compared with entry-level windows.

Step 7: Real Comparison — Value vs Price

Instead of asking:
Which is cheaper?

Ask:
Which system suits the application?

uPVC often performs well for:

• Thermal insulation
• Coastal environments
• Bedrooms
• Standard residential openings

Aluminium may suit:

• Large spans
• Slim aesthetics
• Commercial façades

Many premium homes use a combination.

Step 8: How to Compare Quotes Properly

Before finalising, check:

✔ Profile thickness
✔ Reinforcement
✔ Glass type
✔ Hardware brand
✔ Gaskets
✔ Installation method
✔ Warranty

If a quote only mentions price per sq.ft without specification breakdown, it’s incomplete.

Final Thoughts: Cost Depends on System, Not Just Material

There is no universal answer to:
Which is cheaper — uPVC or aluminium?

Cost depends on:

• System type
• Glass
• Hardware
• Installation
• Configuration

System-driven window providers typically present cost transparently across all components rather than quoting only a basic frame price.

The right choice isn’t the cheapest material.
It’s the right system for your home.
