Cost of Aluminium Windows and Doors

Cost of Aluminium Windows and Doors

The cost of aluminium windows and doors depends on the complete product specification rather than one standard price.

A small fixed aluminium window, a custom double-glazed awning window and a large architectural stacker door all use different quantities of aluminium, glass, hardware and labour.

The final price can be influenced by:

  • Window size
  • Door size
  • Window type
  • Door type
  • Aluminium frame system
  • Glass
  • Double glazing
  • Thermally broken framing
  • Acoustic requirements
  • Hardware
  • Screens
  • Powder-coat finish
  • Quantity
  • Delivery
  • Installation
  • Site access
  • Project complexity

For this reason, the most accurate way to determine aluminium window and door cost is through a project-specific quotation.

EZ Windows provides quotations for residential, renovation, new-build, architectural and commercial aluminium window and door projects.

How Much Do Aluminium Windows and Doors Cost?

There is no single price for aluminium windows and doors because every project can vary significantly in size, glass, frame system and configuration.

A meaningful quotation requires information about the actual products being purchased.

At minimum, pricing normally depends on:

  • Width
  • Height
  • Window or door type
  • Glass
  • Colour
  • Quantity

More complex projects may require additional information.

Why Do Aluminium Window Prices Vary So Much?

Aluminium windows can appear similar while being technically very different.

Two windows of the same overall size may have different prices because one may contain:

  • More opening sashes
  • Different glass
  • Thicker glass
  • Double glazing
  • More hardware
  • A higher-performance frame
  • Different screens

The total window specification therefore matters more than size alone.

What Affects the Cost of Aluminium Windows?

The main factors include:

Window Size

Larger windows generally require more:

  • Aluminium
  • Glass
  • Hardware

Larger glass panels can also require increased glass thickness or additional handling.

Window Type

Different window configurations require different quantities of framing and hardware.

For example:

  • Fixed windows are relatively simple
  • Sliding windows require tracks, rollers and interlocks
  • Awning windows require hinges or stays and locking hardware
  • Combination windows use additional framing

Glass

Glass can significantly influence price.

Options can include:

  • Clear glass
  • Toughened glass
  • Laminated glass
  • Double glazing
  • Low-E glass
  • Acoustic glass
  • Obscure glass

Frame System

Different aluminium systems have different:

  • Profile sizes
  • Aluminium content
  • Glazing capacities
  • Hardware
  • Performance characteristics

Quantity

Larger window packages may offer manufacturing efficiencies compared with producing a very small number of units.

Finish

Powder-coat selection can influence pricing depending on the chosen finish and system.

What Affects the Cost of Aluminium Doors?

Aluminium doors can vary even more significantly than windows because of their size and hardware.

Important factors include:

  • Overall opening width
  • Overall height
  • Number of panels
  • Glass
  • Frame system
  • Rollers
  • Hinges
  • Locks
  • Tracks
  • Thresholds
  • Screens

A two-panel sliding door is very different from a large multi-panel stacker or bifold door.

Cost of Fixed Aluminium Windows

Fixed windows are often among the simpler aluminium window configurations because they contain no opening sash or operating hardware.

Cost is mainly influenced by:

  • Size
  • Glass
  • Frame
  • Finish
  • Quantity

Large fixed windows can still become expensive because of glass size, thickness, transport and installation.

Cost of Aluminium Awning Windows

Awning windows usually cost more than a comparable fixed window because they require:

  • Operable sash
  • Hardware
  • Handles
  • Seals
  • Hinges or stays

Price increases as sash size, glass weight and hardware requirements increase.

Cost of Aluminium Sliding Windows

Sliding windows include moving panels and tracks.

Cost can depend on:

  • Number of panels
  • Fixed/sliding configuration
  • Rollers
  • Locks
  • Flyscreens
  • Glass

Larger sliding windows may also require heavier-duty framing or hardware.

Cost of Aluminium Sliding Doors

Sliding doors can vary considerably in price.

Cost depends on:

  • Door dimensions
  • Number of panels
  • Glass
  • Frame
  • Hardware
  • Roller system
  • Screens
  • Threshold
  • Installation

Large sliding panels can become heavy, which affects both hardware and handling.

Cost of Aluminium Stacker Doors

Stacker doors generally use more panels and hardware than a simple two-panel sliding door.

Cost factors can include:

  • Number of panels
  • Overall opening width
  • Glass
  • Rollers
  • Track system
  • Interlocks
  • Screens

They can provide a wider opening than many standard sliding-door configurations.

Cost of Aluminium Bifold Doors

Bifold doors can be more complex because they use:

  • Multiple panels
  • Hinges
  • Carriers
  • Tracks
  • Locks
  • Seals

The final price depends heavily on the number and size of panels.

Cost of Hinged Aluminium Doors

Hinged aluminium door cost depends on:

  • Door size
  • Frame
  • Glass
  • Locks
  • Hinges
  • Handles
  • Threshold
  • Finish

Commercial or high-use doors may require more substantial hardware.

Does Double Glazing Increase the Cost?

Yes.

Double glazing generally costs more than standard single glazing because the glass unit is more complex.

A double-glazed unit can include:

  • Two panes of glass
  • Spacer
  • Sealed cavity
  • Specialist coatings
  • Laminated panes
  • Toughened panes

The frame must also be capable of supporting the increased glass thickness and weight.

How Much More Does Double Glazing Cost?

There is no universal percentage increase.

The price difference depends on:

  • Window size
  • Glass make-up
  • Frame system
  • Quantity
  • Low-E coating
  • Acoustic requirements

A project-specific comparison is more useful than applying one generic percentage.

Do Thermally Broken Windows Cost More?

Generally, yes.

Thermally broken aluminium systems are more complex than standard aluminium framing.

They incorporate a lower-conductivity material separating internal and external aluminium sections.

These systems are often selected for:

  • Higher-performance homes
  • Large glazed areas
  • Architectural projects
  • Commercial buildings

The additional cost should be considered against the project’s required thermal performance.

Does Acoustic Glass Increase the Cost?

It can.

Acoustic glazing may use:

  • Laminated glass
  • Acoustic laminates
  • Different glass thicknesses
  • Double glazing

The correct specification depends on the required acoustic performance.

It is usually more useful to price the specified acoustic system than estimate a generic surcharge.

Does Low-E Glass Cost More?

Low-E glass generally costs more than basic clear glass because it incorporates a specialised coating.

It may be selected to improve thermal performance.

The cost should be considered alongside the complete building energy strategy.

Does Toughened Glass Cost More?

Toughened glass can cost more than basic annealed glass because of the additional manufacturing process.

Safety glazing requirements should be established according to the project rather than selected solely on price.

Does Laminated Glass Cost More?

Laminated glass generally costs more than basic monolithic glass because it includes multiple layers bonded with an interlayer.

It can be used for:

  • Safety
  • Acoustic performance
  • Other project-specific requirements

Does Window Colour Affect the Price?

It can.

Powder-coated aluminium is available in numerous finishes, but the final cost depends on the selected coating system and colour availability.

Some projects may use:

  • Standard colours
  • Special colours
  • Higher-performance coating systems

The appropriate finish should suit both the architecture and environmental exposure.

Standard vs Custom Aluminium Window Cost

Custom windows can cost more than simple stock-size products because they are made specifically for the project.

However, custom manufacture is common in the aluminium window industry.

For many new homes, renovations and commercial projects, project-specific sizing is normal.

The price depends more on the total specification than the fact that the dimensions are custom.

Are Larger Aluminium Windows More Expensive?

Generally, yes.

Larger windows require more aluminium and glass.

They may also involve:

  • Thicker glass
  • Additional mullions
  • Stronger framing
  • Special transport
  • Special installation

Very large glass panels may require crane or vacuum lifting equipment.

Does Window Height Affect Cost?

Yes.

Tall windows can affect:

  • Glass thickness
  • Frame requirements
  • Wind pressure
  • Handling
  • Installation

Height can therefore influence pricing independently of width.

Does the Number of Opening Sashes Affect Cost?

Yes.

A window with multiple opening sashes generally requires more:

  • Framing
  • Hardware
  • Handles
  • Hinges
  • Locks
  • Seals

than a fixed window of the same overall size.

Do Mullions and Transoms Affect Window Cost?

Yes.

Additional mullions and transoms require more aluminium and additional manufacturing.

However, they may also be necessary for:

  • Structural reasons
  • Glass size
  • Architectural design
  • Opening configuration

They should not simply be removed to reduce cost without considering the complete system.

Does Hardware Affect Aluminium Window Prices?

Yes.

Hardware can include:

  • Handles
  • Locks
  • Rollers
  • Hinges
  • Friction stays
  • Door closers
  • Commercial hardware

Higher-capacity or specialist hardware can increase cost.

Do Flyscreens Add to the Cost?

Yes.

Flyscreens are generally additional components.

Cost depends on:

  • Window size
  • Window type
  • Screen system

Retractable and security screens are usually more specialised than standard insect screens.

Cost of Retractable Flyscreens

Retractable screens can add significant functionality to large door openings.

Pricing depends on:

  • Opening size
  • Screen system
  • Door configuration
  • Installation

They are commonly considered for large sliding, stacker and bifold doors.

Cost of Security Screens

Security screens generally cost more than standard flyscreens because they are designed for a different purpose and use different materials and hardware.

Standard insect screens should not be treated as equivalent to security screens.

Supply-Only vs Installed Aluminium Window Cost

Supply-only and installed pricing are different.

Supply-only pricing generally covers the manufactured windows and agreed delivery arrangements.

Installed pricing can also include:

  • Site labour
  • Removal where included
  • Fixing
  • Equipment
  • Travel
  • Access requirements

The exact installation scope should always be clearly identified.

How Much Does Window Installation Cost?

Installation cost varies considerably according to the project.

Factors can include:

  • New construction vs replacement
  • Window size
  • Floor level
  • Access
  • Number of units
  • Existing building materials
  • Removal requirements
  • Equipment

A simple ground-floor new-build installation and a difficult upper-level replacement job should not be expected to cost the same.

Cost of Replacing Aluminium Windows

Replacement projects can involve costs beyond the new window itself.

Possible additional work can include:

  • Removal of existing windows
  • Disposal
  • Internal finishing
  • External finishing
  • Flashings
  • Sealants
  • Cladding repairs
  • Brickwork repairs
  • Access equipment

The exact scope should be established before quotation.

New Build vs Replacement Window Cost

New-build window installation is often easier to coordinate because the openings can be prepared for the new windows.

Replacement work can involve unpredictable existing conditions.

This does not mean replacement is always more expensive, but it can involve more variables.

Cost of Aluminium Windows for a New Home

The total cost of a full-house aluminium window package depends on:

  • Number of windows
  • Number of doors
  • Total glazing area
  • Window types
  • Door types
  • Glass
  • Frame system
  • Screens
  • Installation

It is therefore more accurate to price the actual window schedule than quote a generic whole-house figure.

Cost of Aluminium Windows for Renovations

Renovations can vary from one replacement window to a complete transformation of the home.

Pricing depends on both:

  • New product specification
  • Existing construction

A renovation that enlarges openings may also involve separate structural and building work outside the window package.

Cost of Aluminium Windows for Commercial Buildings

Commercial projects can involve additional requirements such as:

  • Higher wind pressure
  • Larger glazing
  • Safety glass
  • Acoustic glass
  • Energy requirements
  • Shop drawings
  • Commercial hardware
  • Installation access

These requirements can significantly influence price.

Cost of Aluminium Windows for Apartments

Apartment projects may involve:

  • Acoustic requirements
  • Wind exposure
  • Safety glazing
  • Fall-prevention requirements
  • Double glazing
  • Access equipment

The project documentation should identify the required performance.

Cost of Aluminium Windows for Schools

School and education projects can have specific requirements relating to:

  • Safety
  • Acoustic performance
  • Energy performance
  • Durability
  • Hardware
  • Screens

The price should reflect the actual project specification.

Cost of Aluminium Windows for Architects

Architectural window packages can vary significantly because they often include:

  • Large glazing
  • Custom proportions
  • Special colours
  • Window shrouds
  • High-performance glass
  • Thermally broken systems

The architectural design should be considered alongside the available project budget.

Can I Reduce the Cost of Aluminium Windows?

Yes, but cost reduction should be approached carefully.

Possible strategies include:

  • Simplifying configurations
  • Reducing unnecessary opening sashes
  • Standardising repeated sizes
  • Reviewing glass specifications
  • Reviewing door configurations
  • Using fixed glazing where appropriate

However, changes should not compromise:

  • Required performance
  • Compliance
  • Energy requirements
  • Acoustic requirements
  • Architectural intent

Are Fixed Windows Cheaper Than Opening Windows?

They often can be because fixed windows contain fewer moving components and less hardware.

This makes them useful where ventilation is not required.

A combination of fixed and opening windows can sometimes provide a practical balance of cost and function.

Is a Sliding Window Cheaper Than an Awning Window?

Not always.

Pricing depends on size, glass, frame and configuration.

The best window type should be selected according to the required function rather than price alone.

Are Sliding Doors Cheaper Than Bifold Doors?

Simple sliding doors can often be less complex than bifold doors with multiple panels and hinges.

However, price still depends on:

  • Size
  • Glass
  • System
  • Hardware
  • Number of panels

Are Stacker Doors More Expensive Than Sliding Doors?

They can be because they generally include more panels, tracks and hardware.

The benefit is a wider opening.

Should I Choose Windows Based Only on Price?

No.

Price is important, but windows and doors also affect:

  • Comfort
  • Appearance
  • Ventilation
  • Energy performance
  • Acoustic performance
  • Weather performance
  • Security
  • Maintenance

The cheapest product may not provide the best long-term value for the project.

What Is the Best Value Aluminium Window?

The best-value window is one that meets the actual requirements of the project without adding unnecessary complexity.

For one project, this may be a straightforward fixed or sliding window.

For another, it may be a thermally broken double-glazed system.

Value should be assessed against the intended outcome.

Online Aluminium Window Pricing

Online quotation can make it easier to compare aluminium window options.

Customers can provide:

  • Dimensions
  • Product type
  • Glass
  • Colour
  • Quantity

This creates a clearer basis for pricing than asking for a generic cost per window.

Can Aluminium Windows Be Priced Per Square Metre?

A square-metre figure can sometimes be useful for very broad budgeting, but it can also be misleading.

Two windows with the same area can have very different prices because of:

  • Opening sashes
  • Hardware
  • Glass
  • Frame
  • Mullions

A detailed quotation is more reliable.

Can Aluminium Windows Be Priced Per Unit?

Yes, once the product specification is known.

The unit price should relate to a defined window or door rather than a generic aluminium window.

Why Cheap Aluminium Windows Can Cost More Later

The lowest initial price may not always provide the best long-term outcome.

Possible issues with an unsuitable product can include:

  • Poor operation
  • Inadequate thermal performance
  • Inadequate acoustic performance
  • Higher maintenance
  • Limited glazing capability

The correct product should be selected for the application.

Window Cost and Energy Efficiency

Higher-performance windows may initially cost more.

Options such as:

  • Double glazing
  • Low-E glass
  • Thermally broken framing

can increase the purchase price.

Whether they provide value depends on the project’s climate, orientation, glazing area and energy objectives.

Window Cost and Acoustic Performance

Acoustic windows may require more specialised glass and sealing.

This can increase cost.

Projects with significant traffic, rail or aircraft noise should base the glass selection on the required acoustic outcome rather than price alone.

Window Cost and Architectural Design

Architectural choices can significantly influence cost.

Examples include:

  • Oversized windows
  • Floor-to-ceiling glass
  • Large sliding doors
  • Bifold systems
  • Custom colours
  • Window shrouds

These features can create substantial architectural value but should be budgeted early.

When Should You Request Window Pricing?

Window pricing can be useful at several stages:

  • Early budgeting
  • Design development
  • Tender stage
  • Before construction
  • Before manufacture

Early pricing can identify cost implications before architectural decisions become difficult to change.

What Information Is Needed for an Accurate Quote?

For the most useful quotation, provide:

  • Width
  • Height
  • Window type
  • Door type
  • Glass
  • Colour
  • Screens
  • Quantity
  • Project location
  • Installation requirements

For larger projects, also provide:

  • Architectural plans
  • Window schedule
  • Specifications
  • Energy requirements
  • Acoustic requirements

Preliminary Price vs Final Quote

A preliminary price may be based on incomplete information.

A final quotation should reflect the agreed product and scope.

Pricing can change if:

  • Dimensions change
  • Glass changes
  • Colour changes
  • Quantity changes
  • Hardware changes
  • Installation changes

Final manufacturing information should therefore be confirmed before ordering.

Do Aluminium Window Prices Include GST?

Whether GST is included or excluded should be clearly identified on the quotation.

Customers should check the quotation rather than assume.

Do Window Prices Include Delivery?

Delivery should also be clearly identified.

The cost can depend on:

  • Project location
  • Quantity
  • Product size
  • Site access

Do Window Prices Include Installation?

Not necessarily.

A quotation should clearly identify whether it is:

  • Supply only
  • Supply and delivery
  • Supply and installation

The scope should be reviewed before accepting the quotation.

Do Aluminium Window Quotes Include Removal of Old Windows?

Not automatically.

Removal should only be assumed if it is specifically included in the quotation.

Replacement work can involve additional site-specific requirements.

Does Site Access Affect Installation Cost?

Yes.

Installation can cost more where access requires:

  • Scaffolding
  • Elevated work platforms
  • Cranes
  • Vacuum lifters
  • Additional labour

Site access should be identified during quotation.

Aluminium Window Cost and Large Glass Installation

Very large glass panels can require specialised lifting.

This can influence:

  • Delivery
  • Installation
  • Equipment
  • Labour

Design teams should consider this before finalising extremely large glass sizes.

Aluminium Window Quotes for Builders

Builders can obtain more accurate pricing by supplying:

  • Plans
  • Window schedules
  • Glass specification
  • Project location
  • Required programme

Consistent information makes tender comparison easier.

Aluminium Window Quotes for Architects

Architects can improve cost certainty by defining:

  • Window types
  • Window sizes
  • Glass

How Long Is an Aluminium Window Quote Valid?

Quotation validity can vary according to:

  • Material pricing
  • Supplier pricing
  • Project timing
  • Glass pricing

The quotation should state its applicable validity period.

Aluminium Window Deposits and Payments

Payment arrangements should be confirmed in the accepted quotation or contract.

Custom products are generally manufactured specifically for the project, so customers should understand the payment terms before placing an order.

Compliance and Cost

Compliance requirements should never be removed simply to reduce price.

Project-specific requirements may relate to:

  • Safety glazing
  • Wind pressure
  • Energy performance
  • Acoustic performance
  • Structural requirements

The selected product must remain appropriate for the application.

Warranty and Price

A lower price should not be considered independently from product support and applicable warranty terms.

EZ Windows is an AGWA member and generally provides a six-year product guarantee, subject to written terms, conditions and exclusions.

Where EZ Windows completes installation under an accepted installation scope, the installation warranty is generally one year, subject to the applicable terms.

Powder-coat warranty depends on the actual coating system selected and applied, environmental exposure, cleaning, maintenance and supplier conditions.
