Aluminium windows, especially premium systems, offer:

• Higher strength and rigidity
• Longer lifespan
• Better aesthetics and slim profiles
• Enhanced safety & fire resistance
• Weather stability in Indian conditions
• Premium finishes & colour options
• Real scrap value even after decades

They are simply the best
choice for modern architecture, durability, and long-term peace of mind. See Comparison Table

Safety & Security

Aluminium (✔
High Security)

Strong metal that cannot be easily
cut or broken

Ideal for multi-point locking
systems

Supports toughened and laminated
safety glass easily

Suitable for ground floor, balcony
and high-security applications

UPVC (✘
Can Be Cut Easily)

UPVC is essentially plastic and
can be cut with tools

Not ideal for high-risk or easily
accessible locations

Frame strength limits advanced
locking hardware

Winner: Aluminium –
superior strength and security.

Fire Resistance

Aluminium (✔
Fire Safe)

Non-combustible material

Melting point above 600°C

Suitable for homes, offices,
hospitals & commercial buildings

UPVC (✘
Releases Toxic Fumes When Burning)

Can melt quickly in high heat or
fire

Releases toxic chlorine-based
fumes when burnt

Not recommended where fire safety
is a priority

Winner: Aluminium – safer
in emergency situations.

Weather Resistance

Aluminium (✔
All-Weather Stable)

No swelling in monsoon

No cracking in winter

No softening in extreme summer
temperatures

Perfectly suited for Indian
climate and coastal regions

UPVC (✘
Expands & Contracts with Temperature)

Expansion in heat causes shutters
to jam in frames

Shrinkage in cold leads to gaps
and air leakage

Prone to long-term misalignment
and poor sealing

Winner: Aluminium – stable
and reliable throughout the seasons.

Sound Insulation

Aluminium (✔
Works Brilliantly with Sound-Damping Glass)

Can support heavy, layered
acoustic glass units

Seals efficiently with premium
gaskets and silicon

Excellent noise reduction for main
roads, airports or busy areas

UPVC (✘
Not Effective with Thick Glass)

Frame strength limits maximum
glass thickness

Cannot reliably hold heavy
laminated acoustic glass

Expansion and contraction create
gaps that reduce sound insulation

Winner: Aluminium –
especially when paired with laminated acoustic glass.

Environmental Impact &
Recycling

Aluminium (✔
100% Recyclable With Scrap Value)

Fully recyclable metal with low
wastage

Retains high scrap value even
after decades

Environmentally responsible and
sustainable option

UPVC (✘
No Scrap Value & Plastic Waste)

Zero resale or scrap value

Ends up as non-biodegradable
plastic waste

Manufacturing and disposal have
environmental impact

Winner: Aluminium –
sustainable and eco-conscious.

Maintenance & Longevity

Aluminium (✔
Low Maintenance, Long Life)

Requires only occasional cleaning
with mild soap and water

Powder-coated surfaces last for
many years without fading

No yellowing, cracking or
brittleness

UPVC (✘
High Maintenance Over Time)

Prone to fading and yellowing with
age

Can become brittle and crack in
harsh sunlight

Hardware loosens as the frame
moves and warps

Winner: Aluminium –
long-lasting and hassle-free.

While uPVC is non tech's choice, Aluminum is the preferred material for premium projects. Aluminum offers significantly higher structural strength, allowing for slimmer profiles and larger glass spans.

Unlike the plastic base of uPVC, Aluminum is a non-combustible metal that withstands extreme tropical UV rays without warping, yellowing, or becoming brittle over time.

In India's tropical climate, UV radiation is the primary enemy of window frames. uPVC is a polymer (plastic) that expands and contracts significantly with temperature changes, which often leads to windows jamming in the summer.

•Fire Performance: Aluminum is a metal with a high melting point and does not catch fire. uPVC, being plastic-based, can melt and release hazardous hydrochloric acid fumes during a fire.
