Aluminium Windows Price Guide (With Size-Wise Cost Breakdown)

When building or renovating a home or office space, one of the most important, yet often underestimated, choices you’ll make is the type of windows to install. Aluminium windows have become a staple in modern Indian architecture for their sleek finish, structural strength, low maintenance, and durability.

Whether you’re planning to install aluminium sliding doors for the balcony, double glazed windows, or full-scale aluminium windows and doors, understanding the cost involved helps you make informed decisions without compromising style or performance.

This detailed guide breaks down the aluminium windows price based on size, type, glass configuration, and other cost-affecting factors so you can budget better and select the right window solutions for your space.

Why Choose Aluminium Windows?

Before delving into the price, let’s understand what makes aluminium a top material for doors and windows:

• Durability
  Aluminium doesn’t rust and can handle India’s diverse climate.
• Sleek Aesthetic
  It allows for slim frames, creating a modern look and larger glass panels.
• Low Maintenance
  Aluminium windows require minimal upkeep, enabling decades of use before replacement.
• Customisability
  They are available in various colours, finishes, and glass combinations, such as tinted, laminated, and double-glazed.
• Sustainability
  Aluminium and its alloy Duranium, a specially designed proprietary aluminium alloy developed by Eternia, are 100% recyclable, making them an eco-friendly choice for most households.

Factors That Influence Aluminium Windows Pricing

Understanding what affects the cost of aluminium windows and doors can help you make more value-driven decisions:

• Frame Thickness
  Thicker sections are more expensive but offer better strength and insulation.
• Type of Glass
  Single-glazed, tinted, or double glazed windows all vary in cost.
• Window Type
  Fixed, casement, sliding, or tilt-and-turn configurations each have different pricing.
• Size of the Window
  Larger frames naturally cost more due to more material and labour.
• Opening Mechanism and Accessories
  Premium handles, locks, mosquito mesh, and insulation seals add to the cost.
• Finish and Colour
  Standard silver aluminium is cheaper than powder-coated or wood-textured options.
• Installation and Transportation
  Costs may vary depending on the complexity and location of the installation.

Choosing a Reliable Aluminium Windows and Doors Provider

When choosing a manufacturer for your aluminium windows or doors, ensure you:

• Request a site measurement and estimate.
• Check the quality of the aluminium section.
• Ask for warranty terms (5–10 years is standard).
• Insist on powder-coated or anodised finishes for weather resistance.
• Confirm post-installation support and servicing.

Search locally with queries like “aluminium windows and doors near me” and check reviews, portfolios, and previous work. Visiting a showroom of a leading aluminium window manufacturer like Eternia can also help you visualise frame profiles and glass types.
