What Problems Do Homeowners Face with Aluminium Windows in Delhi — and How to Solve Them

Aluminium windows have become the default choice for modern homes across Delhi NCR. From high-rise apartments in Noida and Gurgaon to builder floors in South Delhi and villas in Greater Noida, aluminium frames are everywhere. They look sleek, allow large glass areas, and are far more durable than old wooden or steel frames.

Yet many homeowners discover after installation that their aluminium windows don’t perform the way they expected. Dust enters, traffic noise remains loud, water leaks during monsoon, and some windows become hard to operate within a few years. These are not small issues — in a city like Delhi, where air pollution, heat, and noise are constant challenges, windows are a critical part of home comfort.

This article takes a practical look at the real problems homeowners face with aluminium windows in Delhi NCR, why they happen, and what can be done to fix or prevent them.

Why aluminium windows are so popular in Delhi NCR

Before discussing problems, it helps to understand why aluminium windows are used so widely.

Aluminium is:

• Strong yet lightweight

• Resistant to termites and rot

• Suitable for large openings and sliding systems

• Compatible with modern architecture

In cities like Delhi, Gurgaon, and Noida, most homes are built with:

• Large balconies

• Big glass windows for natural light

• Compact layouts where sliding windows save space

Aluminium fits these requirements better than wood or steel. However, its performance depends heavily on design, profile quality, installation, and sealing, which is where most problems start.

The Delhi NCR environment creates unique challenges

Delhi NCR is not a mild or forgiving environment for building materials. Windows here must handle:

• Heavy dust and construction pollution

• Extreme summer heat (45°C+)

• Strong monsoon rains and wind

• High traffic noise

• High-rise pressure differences

If aluminium windows are not specified and installed correctly for these conditions, problems appear quickly.

1. Dust entering through aluminium windows

Why it happens

One of the biggest complaints from Delhi homeowners is dust entering the home even when windows are closed. This is common in areas with:

• Construction sites nearby

• Busy roads

• Open plots

The main causes are:

• Poor quality sliding systems

• Gaps between sash and frame

• Low-grade or missing brush seals

• Warped or misaligned shutters

Sliding aluminium windows are especially vulnerable because they do not compress tightly like casement windows.

How to solve it

To reduce dust intrusion:

• Use multi-track sliding systems with proper brush and rubber seals

• Ensure tight manufacturing tolerances so there are no visible gaps

• Prefer casement or tilt-and-turn windows for bedrooms and living areas

• Regularly clean and replace worn brush seals

In high-pollution zones, upgrading from basic sliding windows to better-sealed systems can dramatically improve indoor air quality.

2. Noise coming through the windows

Why it happens

Delhi NCR is one of the noisiest urban regions in India. Traffic, metro lines, honking, and construction never really stop.

Many aluminium windows use:

• Single glass

• Thin frames

• Poor sealing

Sound travels easily through glass and gaps. Even a small air leak can reduce acoustic performance significantly.

How to solve it

Noise control depends on three things:

• Glass

• Sealing

• Frame stability

Effective solutions include:

• Using double-glazed (DGU) or laminated glass

• Installing windows with compression seals instead of loose sliding systems

• Ensuring frames are rigid and properly anchored to the wall

For homes facing busy roads or high-rise towers near expressways, acoustic glass combined with well-sealed aluminium frames can reduce noise by 50–70%.

3. Water leakage during monsoon

Why it happens

Every monsoon, many Delhi homes experience water entering through windows. This is usually due to:

• Improper sill slope

• Missing or blocked drainage holes

• Poor silicone sealing

• Incorrect installation level

Water doesn’t always enter because the window is “bad” — it often enters because the system was not installed or detailed correctly.

How to solve it

A good aluminium window must include:

• Built-in drainage channels

• Weep holes to drain water outward

• Correct sill flashing and slope

• High-quality silicone sealing on all joints

During installation, the frame must be perfectly level and plumb. Even a 2–3 mm tilt can cause water to collect and leak inside.

4. Aluminium windows becoming hard to slide or open

Why it happens

After 1–2 years, many homeowners find that sliding windows:

• Feel heavy

• Get stuck

• Make grinding noises

This happens because:

• Dust enters the tracks

• Cheap rollers wear out

• Tracks are not stainless or properly treated

• Frames were slightly misaligned during installation

Delhi’s dust makes this worse than in cleaner cities.

How to solve it

To keep windows smooth:

• Use stainless steel or heavy-duty rollers

• Choose powder-coated or anodized tracks

• Clean tracks every few months

• Avoid low-cost hardware

High-rise buildings should always use heavy-duty hardware because wind pressure increases load on the shutters.

5. Heat entering through aluminium windows

Why it happens

Delhi summers are extreme. Aluminium is a conductor of heat, and large glass areas allow solar radiation inside. Homes with poorly designed windows feel like greenhouses.

Common issues include:

• Single glass

• Clear glass with no solar control

• Metal frames with no thermal break

How to solve it

To reduce heat:

• Use tinted or reflective glass

• Install double glazing with low-E coating

• Add thermal break profiles where possible

• Use external shading or blinds for west-facing windows

These measures can lower indoor temperature by several degrees and reduce AC usage.

6. Condensation on glass and frames

Why it happens

In winter, warm indoor air meets cold glass, causing moisture to condense. This is common in high-rise apartments where temperature differences are larger.

It leads to:

• Water on window sills

• Mold near frames

• Damage to wall finishes

How to solve it

Condensation is reduced by:

• Double glazing

• Better room ventilation

• Proper sealing so humid air doesn’t get trapped

It’s not an aluminium problem — it’s a glass and airflow problem.

7. Safety and security concerns

Why it happens

Some aluminium windows in Delhi NCR use:

• Thin profiles

• Weak locks

• No reinforcement

This makes them easier to force open, especially on lower floors or balconies.

How to solve it

For safety:

• Use multi-point locking systems

• Choose thicker aluminium profiles

• Install laminated or toughened glass

• Add child-safety restrictors for high-rise homes

Security should never be compromised for slim looks.

8. Poor appearance after a few years

Why it happens

Low-quality powder coating fades, peels, or develops white spots due to:

• Pollution

• UV exposure

• Moisture

How to solve it

Always choose:

• High-micron powder coating

• Reputed aluminium brands

• Proper surface preparation

Good aluminium windows should look new for 10–15 years with minimal maintenance.

Choosing the right aluminium windows for Delhi NCR

The key takeaway is this:Most problems do not come from aluminium itself — they come from poor design, low-quality materials, and improper installation.

Delhi NCR homes need windows that are:

• Well sealed

• Dust resistant

• Noise reducing

• Heat controlling

• Built for high-rise wind pressure

When these factors are addressed at the design and installation stage, aluminium windows perform extremely well in Delhi’s harsh environment.

Frequently Asked Questions (FAQs)

1. Are sliding aluminium windows bad for dust in Delhi?

Not all sliding windows are bad, but basic systems without proper brush and rubber seals allow dust to enter. High-quality multi-track sliding systems or casement windows perform much better in dusty areas.

2. Can existing aluminium windows be upgraded for noise reduction?

Yes. In many cases, replacing the glass with laminated or double-glazed units and improving sealing can significantly reduce noise without changing the entire frame.

3. Why do my aluminium windows leak during heavy rain?

Leaks usually come from poor installation, blocked drainage holes, or incorrect sill slope — not from the aluminium frame itself. A professional inspection can identify and fix the problem.

4. Do aluminium windows make a home hotter in summer?

They can if single glass and clear glass are used. With proper glazing and coatings, aluminium windows can actually help reduce heat compared to old steel or wooden frames.

5. How long should aluminium windows last in Delhi NCR?

Good quality aluminium windows with proper coating and hardware can easily last 20–25 years in Delhi NCR with basic maintenance.

6. Are aluminium windows safe for high-rise apartments?

Yes, when designed with thick profiles, proper anchoring, and safety glass. Many international high-rise buildings use aluminium systems because of their strength and durability.
