Aluminium Windows and Doors Pricing: What Factors Influence the Cost?

Aluminium windows and doors have become a preferred choice for modern Indian homes due to their durability, sleek design, and long-term performance. Whether you are building a new home or renovating an existing one, understanding the factors that influence the cost of aluminium windows and doors helps you make informed decisions and plan your budget realistically. Many homeowners search for an aluminium window or door price list, only to realise that pricing varies widely based on several factors.

Rather than being a fixed number, the cost of aluminium systems depends on design choices, materials, performance requirements, and installation conditions. Eternia, a premium aluminium window and door brand from Hindalco, focuses on engineered performance and durability rather than mass-produced, one-size-fits-all pricing.

This guide breaks down the key factors that influence aluminium window and door pricing so you know exactly what you are paying for.

Why Aluminium Pricing Varies So Much?

Unlike basic building materials, aluminium windows and doors are engineered systems. Their price reflects not just the metal frame, but also the design complexity, glass selection, performance testing, and finishing quality. When comparing aluminium window prices online, it is important to understand that listed prices may not include customisation, installation, or performance upgrades.

Factor 1: Quality of Aluminium Used

The type and quality of aluminium play a major role in pricing. Premium aluminium alloys offer greater strength, durability, and resistance to weathering.

Eternia uses Duranium, a proprietary aluminium alloy developed by Hindalco that is 40 per cent stronger than standard aluminium alloys. This added strength allows for slimmer profiles, wider glass panels, and longer lifespan, all of which influence the overall aluminium door price and window cost.

Higher grade aluminium:

• Improves structural stability
• Supports larger openings
• Performs better in high wind and rain
• Lasts longer with minimal maintenance

Lower-grade aluminium may appear cheaper initially, but can lead to higher maintenance or replacement costs over time.

Factor 2: Window or Door Design Type

The design you choose has a direct impact on pricing. Different systems require different levels of engineering and material usage.

Common design options include:

• Sliding windows and doors
• Casement openable windows
• Fixed glass windows
• French windows and doors
• Lift and slide doors
• Folding or slide and fold doors

For example, a basic sliding window generally costs less than a large folding door system due to differences in hardware, panel size, and installation complexity. This is why an aluminium door price list often shows a wide range rather than a single figure.

Factor 3: Size and Dimensions

Aluminium systems are usually customised to fit your opening. Larger windows and doors require more aluminium, bigger glass panels, and stronger support.

Pricing increases with:

• Greater width and height
• Floor-to-ceiling designs
• Wide patio or balcony openings
• Oversized glass panels

Homes with large openings or panoramic designs typically have higher aluminium window prices due to the additional material and engineering required.

Factor 4: Type of Glass Selected

Glass selection is one of the most important cost drivers. Aluminium frames can support multiple glass options, each with different performance characteristics.

Common glass options include:

• Toughened glass
• Laminated glass
• Acoustic laminated glass
• Double-glazed glass
• Double-glazed laminated glass
• Tinted glass
• Frosted glass

Advanced glass options improve insulation, noise reduction, safety, and comfort, but they also increase overall cost. When reviewing aluminium window prices online, glass specifications are often the reason for price differences between similar-looking systems.

Factor 5: Performance Requirements

Windows and doors that face outdoors must perform well against wind, rain, dust, and noise. Systems tested for higher performance standards usually cost more because of better engineering and sealing.

Eternia windows undergo WiWA testing to measure:

• Wind resistance up to 2.75 kPa
• Water tightness up to 750 Pa
• Air sealing up to 600 Pa

This level of performance is especially important for high rise apartments, coastal homes, and properties exposed to harsh weather. Strong performance directly affects the aluminium door price and window pricing.

Factor 6: Hardware Quality

Handles, locks, rollers, and other hardware components contribute to both functionality and pricing.

High quality hardware:

• Improves smoothness of operation
• Enhances safety and security
• Supports heavier glass panels
• Extends the life of the system

Premium systems use durable hardware designed for frequent use, which reflects in the overall cost.

Factor 7: Frame Finish and Colour

Aluminium frames are available in multiple finishes and colours, each with its own production process.

Eternia offers premium finishes such as Pearl White, Moon Silver, Graphite Grey, Earth Grey, Glacier Grey, Night Black, Starlight Black, Teak Wood, Oak Wood, Walnut Wood, and Dusk Gold. Special finishes and wood-grain textures typically influence pricing more than standard colours, due to additional processing and coating requirements.

Factor 8: Customisation and Design Complexity

Custom designs increase cost because they require additional planning, fabrication, and precision.

Examples include:

• Corner windows
• Combination windows with fixed and openable sections
• Multi-panel sliding systems
• Unique layouts for balconies or terraces

Customisation ensures the system fits perfectly into your home design, but it also adds to the aluminium window price.

Factor 9: Installation Conditions

Installation is a crucial part of the overall cost. Pricing can vary depending on:

• Type of wall structure
• Height of installation
• Accessibility of the opening
• Replacement versus new construction

Professional installation ensures proper alignment, sealing, and long term performance. Poor installation can compromise even the best aluminium systems.

Factor 10: Brand, Warranty, and Long-Term Value

Reputed brands invest in material quality, testing, and after-sales support. Eternia offers:

• 12-year warranty on aluminium profiles
• 5-year warranty on hardware

While premium brands may not always offer the lowest upfront cost, they provide better long term value through durability, performance, and reduced maintenance.

Why Aluminium for Windows Is a Long-Term Investment

When evaluating aluminium pricing, it is essential to look beyond the initial cost.

Benefits of aluminium for windows include:

• Long lifespan
• Minimal maintenance
• Resistance to rust, warping, and moisture
• Stable performance over time
• Modern aesthetic appeal
• Sustainability through recyclability

A well engineered aluminium system often proves more economical over time than cheaper alternatives that require frequent repairs or replacement.

Conclusion

The pricing of aluminium windows and doors depends on multiple interconnected factors rather than a single fixed rate. Design type, size, glass selection, performance requirements, finishes, and installation all contribute to the final aluminium door price and aluminium window price. Understanding these elements helps homeowners choose systems that match their needs and budget.

Instead of focusing only on an aluminium door price list or aluminium window prices online, it is wiser to evaluate the overall value, durability, and performance of the system. With premium materials, strong engineering, and reliable performance, Eternia aluminium windows and doors offer a long-term solution for modern Indian homes.
