Aluminium Window and Door Lead Times

Aluminium Window and Door Lead Times

Understanding aluminium window and door lead times is important for builders, homeowners, architects and renovators because custom windows and doors are rarely an off-the-shelf product.

Lead time can be affected by:

  • Final measurements
  • Shop-drawing approval
  • Window and door quantity
  • Product type
  • Glass
  • Powder-coat finish
  • Hardware
  • Special components
  • Manufacturing workload
  • Delivery
  • Installation scheduling

The most important point is that lead time should be based on the actual approved order rather than a generic number.

How Long Do Aluminium Windows and Doors Take?

Aluminium window and door lead times vary by project and should be confirmed at the time of order.

Simple standard-style products may move through production faster than complex architectural or highly customised orders.

A realistic programme should allow time for:

  1. Finalising the specification
  2. Confirming dimensions
  3. Approving drawings where required
  4. Ordering glass and components
  5. Fabrication
  6. Finishing
  7. Quality checks
  8. Delivery or installation

Why Lead Times Vary

Two orders of the same total value can have very different production timelines.

For example, one project might contain:

  • Repeated standard sliding windows
  • One colour
  • Standard glass

Another might contain:

  • Custom combination windows
  • Large fixed glazing
  • Thermally broken frames
  • Special glass
  • Multiple colours
  • Oversized doors

The second project will generally involve more coordination.

When Does Lead Time Actually Start?

This is an important question.

Lead time should generally be considered from the point at which the order is sufficiently complete and approved to proceed.

That may require:

  • Deposit or purchase order
  • Final dimensions
  • Approved drawings
  • Confirmed glass
  • Confirmed colour
  • Confirmed hardware

If critical information is missing, manufacturing may not be able to commence.

Quote Date Is Not the Same as Production Start Date

Receiving a quotation does not automatically reserve a production slot.

A quotation may remain valid for a defined period, but production normally begins only after the order has been formally accepted and the required information has been supplied.

Approved Shop Drawings and Lead Times

Where shop drawings are required, production usually depends on their approval.

Shop drawings may confirm:

  • Overall sizes
  • Window types
  • Door configurations
  • Mullions
  • Transoms
  • Opening directions
  • Glass
  • Colour
  • Hardware

Changes after approval can affect the programme.

Why Shop-Drawing Delays Matter

If drawings are issued but not approved promptly, the production programme can move.

This is especially important for builders working to fixed site dates.

Approvals should therefore be treated as a project milestone.

Final Measurements and Lead Times

Manufacturing cannot reliably proceed where final dimensions are still uncertain.

For renovation and replacement projects, final site measurement may be required before manufacture.

Delays in gaining access to site can therefore affect the programme.

Preliminary Sizes vs Final Sizes

Preliminary dimensions can be used for:

  • Budgeting
  • Tendering
  • Early quotation

Final manufacturing dimensions require confirmation.

A price based on approximate sizes should not automatically be treated as ready for production.

Standard vs Custom Aluminium Window Lead Times

Custom aluminium windows are common.

The fact that a window is custom-sized does not automatically mean it has an excessive lead time.

However, complexity can increase production time.

Factors include:

  • Unusual sizes
  • Non-standard layouts
  • Special glass
  • Special colours
  • Complex hardware

Window Quantity and Lead Time

Larger orders require more manufacturing time.

A project containing:

  • 4 windows

and a project containing:

  • 80 windows and doors

cannot necessarily follow the same schedule.

Large projects may also be delivered in stages.

Staged Window Production

Staging can be useful on larger projects.

For example:

  • Ground floor first
  • Upper floor later
  • Stage 1 townhouses
  • Stage 2 townhouses

This can help align production with the builder’s site programme.

Aluminium Awning Window Lead Times

Awning windows are commonly manufactured products.

Lead time depends on:

  • Size
  • Quantity
  • Glass
  • Hardware
  • Finish

Large or unusual sashes may require additional consideration.

Aluminium Sliding Window Lead Times

Sliding windows can often be efficiently repeated across larger residential projects.

However, lead time still depends on:

  • Frame system
  • Glass
  • Quantity
  • Colour
  • Screens

Fixed Window Lead Times

Fixed windows can be relatively straightforward from a hardware perspective.

Very large fixed panes, however, may involve additional glass procurement and handling requirements.

Sashless Window Lead Times

Sashless systems can involve specialised components.

Availability of:

  • Glass
  • Hardware
  • System components

can affect production timing.

Sliding Door Lead Times

Sliding doors involve larger frame assemblies and heavier glass than many windows.

Lead time can be influenced by:

  • Panel size
  • Glass
  • Roller systems
  • Locks
  • Screens

Stacker Door Lead Times

Stacker doors contain multiple moving panels and often larger amounts of glass.

The configuration should be approved before production.

Bifold Door Lead Times

Bifold doors can require more complex hardware and assembly.

Lead time may depend on:

  • Panel count
  • Hardware
  • Glass
  • Finish

Because multiple panels must operate together, accuracy is particularly important.

Hinged Door Lead Times

Hinged doors can vary from simple glazed doors to more complex entrance assemblies.

Lead time depends on:

  • Frame
  • Door leaf
  • Locks
  • Handles
  • Glass
  • Finish

Double-Glazed Window Lead Times

Double glazing can affect overall lead time because insulated glass units are manufactured to the required size and specification.

Factors can include:

  • Glass make-up
  • Low-E coatings
  • Laminated panes
  • Toughened panes
  • Unit size

Glass availability should be confirmed for the actual project.

Acoustic Glass Lead Times

Special acoustic glazing may require additional procurement.

This is especially relevant where the design specifies:

  • Acoustic laminate
  • Specific glass thicknesses
  • Complex double-glazed make-ups

Specialist products should be confirmed early.

Low-E Glass Lead Times

Low-E glass is widely used, but availability can vary depending on the exact product and glass make-up.

Selecting the glass early can reduce late-stage changes.

Obscure Glass Lead Times

Some privacy glass patterns or products may have different availability from standard clear glass.

This can be relevant when a specific pattern is required.

Special Glass Can Affect the Programme

Specialist glass should be identified at quotation stage wherever possible.

Examples include:

  • Oversized glass
  • Acoustic glass
  • Laminated glass
  • Solar-control glass
  • Special obscure glass

Late substitution can affect manufacturing.

Powder-Coat Lead Times

Powder coating forms part of the production process for many aluminium windows and doors.

Lead time can be influenced by:

  • Colour
  • Finish
  • Coating system
  • Powder availability
  • Batch scheduling

Standard Colours vs Special Colours

Standard production colours may be more readily available than less common finishes.

Special colours can potentially involve:

  • Powder procurement
  • Minimum batch requirements
  • Additional scheduling

This should be established before the order is placed.

Metallic and Textured Finishes

Special architectural finishes may require different production arrangements.

Where appearance is critical, physical samples should be approved before manufacture.

Dual-Colour Window Lead Times

Systems using different internal and external colours can involve additional manufacturing complexity.

Where dual colour is available, it may influence both:

  • Price
  • Lead time

Hardware and Lead Times

Windows and doors rely on a range of components, including:

  • Locks
  • Handles
  • Rollers
  • Hinges
  • Restrictors
  • Closers

Unusual or specialised hardware can affect the programme if it is not readily available.

Security Screens and Lead Times

Security screens may be manufactured separately from the windows and doors.

If screens are part of the package, their lead time should be considered within the complete project programme.

Retractable Screens and Lead Times

Retractable flyscreens are specialised products.

Their manufacturing or procurement schedule may differ from the aluminium window or door itself.

They should be ordered early where they form an important part of the project.

Large Glass and Lead Times

Oversized glass can require:

  • Specialist manufacturing
  • Additional transport arrangements
  • Lifting equipment

This can extend project coordination.

Large Window Frames and Lead Times

Oversized frame assemblies can also require additional fabrication and handling time.

Site access should be checked before manufacture.

Thermally Broken Aluminium Window Lead Times

Thermally broken systems may use different profiles and components from standard aluminium systems.

Lead times should be confirmed specifically for the selected system.

Replacement Window Lead Times

Replacement projects generally involve two distinct stages:

  1. Measurement and manufacture
  2. Removal and installation

The site cannot normally be completed until the replacement windows are ready.

This makes accurate coordination important.

Whole-House Replacement Lead Times

Replacing every window in a home can involve:

  • Site measure
  • Product selection
  • Glass selection
  • Manufacturing
  • Installation staging

Larger replacement projects should be planned well before the intended construction date.

Renovation Window Lead Times

Renovation projects often depend on other trades.

For example:

  • Framing
  • Brickwork
  • Cladding
  • Plaster
  • Joinery

The window order should therefore be integrated into the broader programme.

New Home Window Lead Times

New-home projects can often plan window procurement from architectural drawings before the building reaches window-installation stage.

However, final site dimensions may still need confirmation depending on the project.

Builder Window Lead Times

Builders should allow enough time for:

  • Tendering
  • Final selection
  • Shop drawings
  • Approval
  • Production
  • Delivery

Leaving window ordering until the opening is physically ready can create unnecessary programme pressure.

Architect-Specified Window Lead Times

Architectural projects may involve additional approvals.

These can include:

  • Frame profile
  • Mullion layout
  • Glass
  • Powder coating
  • Hardware
  • Shop drawings

Early coordination can reduce late-stage substitutions.

Commercial Window Lead Times

Commercial projects can involve larger quantities and more complex logistics.

Programme considerations can include:

  • Staged deliveries
  • Crane access
  • Site inductions
  • Installation sequencing

The window schedule should be coordinated with the head contractor’s programme.

School Window Lead Times

School and education projects can be programme-sensitive because installation may need to occur during:

  • Holidays
  • Shutdown periods
  • Low-occupancy periods

Orders should be placed with the required installation window in mind.

Government Project Lead Times

Government projects can involve formal approvals and procurement processes.

Lead times should account for:

  • Specification review
  • Tendering
  • Approvals
  • Manufacturing
  • Site programme

Apartment Project Lead Times

Apartment projects may involve high quantities and repeated window types.

Efficient scheduling can include:

  • Floor-by-floor production
  • Building-stage delivery
  • Numbered window schedules

Townhouse Project Lead Times

Townhouse developments can often benefit from repeated window types.

This can make production more efficient, provided:

  • Sizes
  • Colours
  • Glass
  • Configurations

are standardised and approved early.

Volume Builder Lead Times

Volume builders benefit from consistency.

Repeated product specifications can support:

  • Faster quoting
  • Easier scheduling
  • Repeat manufacturing

Frequent specification changes can reduce these efficiencies.

Supply-Only Window Lead Times

For supply-only orders, the manufacturing lead time should be coordinated with the customer’s installation programme.

The customer should ensure:

  • Dimensions are correct
  • Site is ready
  • Suitable unloading is available

Installed Window Lead Times

Installed projects include both:

  • Manufacturing
  • Installation scheduling

The installation date may depend on:

  • Site readiness
  • Weather
  • Access
  • Installer availability

Weather and Installation Lead Times

External installation can be affected by weather.

Rain, high winds or unsafe conditions may require rescheduling.

Manufacturing completion and installation date are therefore not always the same milestone.

Delivery Lead Times

Once manufacturing is complete, delivery must also be scheduled.

Factors include:

  • Project location
  • Order size
  • Vehicle requirements
  • Site access

Interstate Window Deliveries

Interstate projects require additional logistics.

This may include:

  • Freight
  • Packaging
  • Delivery coordination

Transit time should be included in the project programme.

Modular Products and Freight

Where products are specifically designed for more efficient transport, freight logistics may be simplified.

However, window and door products still require appropriate protection and handling.

Delivery to Restricted Sites

Sites with restricted access can require:

  • Smaller trucks
  • Delivery windows
  • Traffic management
  • Additional handling

These requirements should be identified before dispatch.

Crane and Vacuum Lifting

Large glass or oversized windows may require:

  • Crane
  • Glass vacuum lifter
  • Specialist installation crew

Equipment availability should be programmed in advance.

Site Readiness

The site should be ready before windows are delivered for installation.

Typical considerations include:

  • Openings complete
  • Safe access
  • Structural work complete
  • Scaffolding available where required
  • Floor levels established

Poor site readiness can cause delays.

What Can Delay an Aluminium Window Order?

Common causes include:

  • Late dimensions
  • Drawing changes
  • Unapproved shop drawings
  • Glass changes
  • Colour changes
  • Hardware changes
  • Site delays
  • Access problems
  • Special material availability

Late Design Changes

Changing the specification after production has started can create substantial delay.

Examples include changing:

  • Size
  • Opening direction
  • Glass
  • Colour
  • Configuration

Some changes may require remanufacture.

Late Colour Changes

Once aluminium has been ordered, cut or coated, changing colour can be costly and disruptive.

Colour should therefore be approved before production.

Late Glass Changes

Changing from basic glass to:

  • Double glazing
  • Acoustic glass
  • Laminated glass

can affect:

  • Frame compatibility
  • Weight
  • Hardware
  • Production

Glass should be resolved early.

Incorrect Measurements

Incorrect dimensions can cause serious delays if windows require alteration or remanufacture.

This is why final dimensions should be approved before manufacture.

Builder Programme Changes

Construction programmes frequently move.

If a project’s installation date changes, notify the supplier as early as possible.

This allows production and delivery planning to be adjusted where possible.

Can Lead Times Be Expedited?

Sometimes, depending on:

  • Production capacity
  • Product type
  • Component availability

However, expedited manufacturing should never be assumed.

An urgent programme should be discussed before the order is placed.

Does Paying More Guarantee a Faster Lead Time?

Not necessarily.

Some lead-time constraints involve:

  • Glass manufacture
  • Powder coating
  • Component supply
  • Production capacity

These may not be solved simply through additional cost.

Should I Order Windows Early?

Yes, but only when the necessary information is sufficiently resolved.

Ordering too late risks programme delays.

Ordering too early with uncertain sizes creates a different risk.

The best approach is early planning followed by timely final approval.

How Early Should Builders Request Pricing?

Builders should request pricing during the tender or procurement stage rather than waiting until windows are immediately required on site.

This allows time to:

  • Compare systems
  • Resolve specification
  • Clarify exclusions
  • Plan production

Can Windows Be Ordered Before Final Site Measurement?

Potentially, where approved drawings and construction dimensions provide sufficient certainty.

However, the party accepting responsibility for dimensions should be clearly identified.

Can Production Start Before Shop Drawings Are Approved?

Usually this is undesirable where drawings form part of the approval process.

Manufacturing against unapproved information can create significant risk.

What Is a Production Slot?

A production slot is an allocated place within a manufacturer’s production programme.

Specific scheduling practices vary.

Customers should not assume a quotation automatically reserves a slot.

Production Capacity

Lead times can change throughout the year depending on demand.

This is another reason current lead times should be confirmed at the point of ordering.

Holiday Periods

Public holidays and industry shutdown periods can affect:

  • Manufacturing
  • Powder coating
  • Glass supply
  • Freight
  • Installation

Projects around major holiday periods should be scheduled early.

Christmas and New Year

The construction industry often experiences reduced operations around Christmas and New Year.

Orders required around this period should be planned well in advance.

Lead Times and Aluminium Window Prices

A tight construction programme can increase logistics complexity.

However, customers should avoid comparing suppliers solely on quoted lead time.

Also consider:

  • Product suitability
  • Glass
  • Finish
  • Service
  • Reliability
  • Installation
  • Warranty

Shortest Lead Time Is Not Always the Best Choice

An unrealistic lead time has little value if the product is not delivered as promised.

A reliable production programme can be more valuable than an aggressive estimate that cannot be achieved.

How to Reduce Window Lead-Time Risk

A practical approach is to:

  1. Request pricing early.
  2. Finalise the product system.
  3. Confirm sizes.
  4. Confirm glass.
  5. Confirm colour.
  6. Approve drawings quickly.
  7. Place the order.
  8. Keep the supplier updated on site programme changes.

Send Complete Information With the Quote Request

The more complete the information, the easier it is to establish a realistic programme.

Useful information includes:

  • Plans
  • Window schedule
  • Dimensions
  • Glass
  • Colour
  • Hardware
  • Screens
  • Required date
  • Project location

Required Date vs Preferred Date

Be clear whether a date is:

  • Preferred
  • Required
  • Critical to the construction programme

This helps prioritise programme discussions.

Completion Date vs Delivery Date

These are different.

A manufacturing completion date means the product may be ready.

Delivery may still need to be booked.

Delivery Date vs Installation Date

These are also different.

Where EZ Windows is installing, installation must be scheduled separately from production completion.

Ready for Collection

Supply-only customers may arrange collection after the order is confirmed as ready.

Collection should not be organised before formal confirmation.

Partial Deliveries

Larger orders may sometimes be split into stages where appropriate.

This can help builders keep work progressing.

However, staging should be agreed in advance.

Storage of Windows On Site

Windows should not be delivered substantially earlier than required if safe storage is unavailable.

Improper storage can expose products to:

  • Damage
  • Site traffic
  • Contamination
  • Theft

The delivery programme should align with site readiness.

Protecting Windows After Delivery

Once delivered, products should be protected from:

  • Impact
  • Grinding
  • Welding
  • Cement
  • Render
  • Harsh chemicals

Damage caused by later construction activities should be avoided.

Lead Times and Warranty

The manufacturing programme does not alter the need to properly inspect, install and maintain the product.

Applicable warranties remain subject to the relevant written terms and conditions.

EZ Windows Lead-Time Approach

EZ Windows aims to provide realistic production information based on the actual project scope.

Lead times are confirmed according to factors including:

  • Product
  • Glass
  • Finish
  • Quantity
  • Supplier availability
  • Production programme
  • Delivery or installation requirements

Where a project has a critical deadline, it should be identified before order acceptance.

Why EZ Windows Does Not Publish One Universal Lead Time

A single advertised number can be misleading.

A basic residential window and a large architectural double-glazed door package do not require the same production process.

Providing the project information allows a more realistic programme to be established.

Frequently Asked Questions About Aluminium Window and Door Lead Times

How long do aluminium windows take to manufacture?

It varies according to the product, glass, finish, quantity and current production programme.

How long do aluminium doors take?

Door lead times also depend on size, system, glass, hardware and finish.

Are custom windows slower?

Not necessarily. Custom sizing is normal in aluminium fabrication, although unusual complexity can add time.

Does double glazing take longer?

It can because the insulated glass units are manufactured specifically for the order.

Does Low-E glass affect lead time?

Potentially, depending on the selected product and availability.

Does acoustic glass take longer?

Special acoustic glass can require additional procurement compared with common glazing.

Does powder-coat colour affect lead time?

It can. Special colours, finishes or coating systems may require additional scheduling.

Do standard colours arrive faster?

They may be more readily available, but current production timing should still be confirmed.

Does dual colour take longer?

Potentially, because dual-colour systems can involve additional processing.

When does the lead time start?

Generally once the order, dimensions and required approvals are sufficiently complete to proceed.

Does accepting a quote start production?

Not automatically. The required deposit, purchase order, drawings or other approval conditions may also need to be satisfied.

Do shop drawings affect lead time?

Yes. Production can be delayed while drawings remain unapproved.

Can you manufacture from approximate measurements?

Approximate dimensions can be used for pricing, but final manufacturing dimensions should be approved.

Can an aluminium window order be rushed?

Sometimes, depending on production and component availability, but expedited lead times should be agreed before ordering.

Can production start before the building is ready?

Potentially, if dimensions and specifications are sufficiently certain and approved.

Does installation take place immediately after manufacture?

Not necessarily. Installation also depends on site readiness, weather and installer scheduling.

Can rain delay window installation?

Yes. Unsafe or unsuitable weather can affect external installation.

Can large glass delay a project?

It can where specialist manufacturing, transport or lifting equipment is required.

Can windows be delivered interstate?

Yes, where freight arrangements are suitable. Transport time should be added to the project programme.

Should I order all windows at once?

That depends on the project. Larger developments can sometimes benefit from staged orders and deliveries.

Can a window order be split into stages?

Potentially, if this is agreed and suitable for the project.

Why do window lead times change?

Production demand, material availability, supplier schedules and project complexity can all change over time.

When should I order windows for a renovation?

Early enough to allow measurement, approvals and manufacture before the planned installation stage.

When should builders order windows?

Window procurement should ideally be incorporated into the construction programme well before the required installation date.

Can late changes delay the order?

Yes. Changes to sizes, glass, colour or configuration can affect production and may require new components or remanufacture.
