How to Choose Aluminium Windows That Withstand High Wind Speeds and Rain

September 17, 2025

Living in a city or coastal region of India means dealing with unpredictable weather, scorching summers, heavy monsoon rains, and at times, gusty winds that test the durability of your home. While walls and roofs are often built to handle such challenges, windows remain one of the most vulnerable parts of a house. Choosing the right aluminium window is therefore crucial, not only for protection but also for maintaining comfort, energy efficiency, and style.

Modern windows in aluminium are strong, sleek, and built to resist weather extremes. But not every aluminium frame or glass system is made equal. If you live in areas that face high wind speeds and heavy rains, such as Mumbai, Chennai, Visakhapatnam, or Goa, it becomes even more important to know what features to look for before making an investment.

That’s why choosing the right aluminium window is not just a design decision but also a matter of safety, comfort, and long-term durability.

Why Aluminium Windows Are Ideal for Harsh Weather?

The popularity of windows in aluminium has grown steadily in India due to their strength and versatility. Compared to wooden or uPVC alternatives, aluminium is naturally better equipped to deal with high winds and heavy rain.

Here’s why aluminium stands out:

  • Strength-to-Weight Ratio
    Aluminium is light yet incredibly strong, making it suitable for large panes without compromising safety.
  • Corrosion Resistance
    Powder-coated finishes protect against rust and salty air, perfect for coastal homes
  • Design Flexibility
    Sliding, fixed, or custom systems to suit every space.
  • Low Maintenance
    Unlike wood, it doesn’t warp or rot, and unlike steel, it doesn’t rust.

This combination makes aluminium windows a long-term investment for homes in weather-prone regions. With the right system design, aluminium windows sliding and fixed formats can easily handle high wind speeds and heavy rains.

Key Features to Look for in Aluminium Windows

When selecting an aluminium window for your home, especially in areas exposed to strong winds and rain, certain features ensure better protection and performance.

  1. Strong Frames & Profiles
    Opt for heavy-duty aluminium sections with higher wall thickness to prevent bending or warping.
  2. Advanced Weather Sealing
    Look for windows with EPDM gaskets, multi-point locking, and dual sealing systems to stop leaks and draughts.
  3. High-Performance Glass

    • Laminated Glass
      Shatter-resistant, ideal for cyclone zones.
    • Double-Glazed Glass
      Adds insulation and strength.
    • Tempered Glass
      Several times stronger than normal glass.
  4. Tested and Certified windows
    Ensure your window system complies with BIS (Bureau of Indian Standards) norms for wind load performance and the system are tested and certified as per international standards for Wind, Water and Air Performance
  5. Efficient Drainage Design
    Built-in drainage channels allow rainwater to flow out, preventing seepage indoors.

Sliding vs Fixed Aluminium Windows in High-Wind Zones

Homeowners often debate whether aluminium windows sliding are as effective as casement windows/openable windows in areas exposed to strong winds and rain. Both have their place, depending on the room and exposure.

  • Casement Windows

    • Best for direct wind-facing walls.
    • Offer maximum sealing and resistance to water ingress.
    • OPt for fixed windows for high-rise apartments where ventilation from certain directions isn’t necessary.
  • Sliding Aluminium Windows

    • Provide ventilation and ease of use.
    • Modern designs feature improved interlock systems and reinforced tracks that perform well under harsh weather.
    • Perfect for living rooms, balconies, or bedrooms where airflow is needed without compromising safety.

A balanced mix of openable and aluminium windows sliding ensures both protection and usability.

Benefits of Aluminium Windows in Rainy and Windy Areas

Choosing durable windows in aluminium offers several benefits beyond storm protection:

  1. Better Indoor Comfort
    Keeps rain and draughts out while maintaining a consistent indoor temperature.
  2. Energy Efficiency
    Reduces strain on air conditioners and dehumidifiers by minimising leakage.
  3. Noise Insulation
    Laminated or double-glazed glass reduces external noise, a big plus in busy urban areas.
  4. Aesthetic Appeal
    Sleek aluminium designs elevate the modern look of any home.
  5. Longevity
    Aluminium resists corrosion and maintains structural integrity for decades.

Tips for Choosing the Right Aluminium Window Supplier

The best window design won’t help if the product quality or installation is poor. Keep these in mind:

  • Check Certifications
    Ensure compliance with Indian standards for wind load and water tightness.
  • Ask About Customisation
    Reputable suppliers offer tailored solutions depending on your location and building design.
  • Compare Warranty
    Long warranties are usually a sign of high-quality materials and manufacturing.
  • Professional Installation
    Choose certified installers who understand sealing, alignment, and drainage requirements.
