Aluminium Window and Door Installation Guide

Aluminium Window and Door Installation Guide

Correct installation is one of the most important parts of achieving reliable performance from aluminium windows and doors.

This aluminium window and door installation guide explains the main principles that should be considered when installing new or replacement aluminium windows and doors in Australian homes and buildings.

Installation can affect:

  • Operation
  • Weather resistance
  • Drainage
  • Appearance
  • Frame alignment
  • Glass performance
  • Door movement
  • Seal performance
  • Long-term serviceability

Even a well-manufactured window can perform poorly if it is installed incorrectly.

How Should Aluminium Windows and Doors Be Installed?

Aluminium windows and doors should be installed into a suitably prepared opening, positioned square, level and plumb, securely fixed, correctly flashed and sealed, and coordinated with the surrounding wall, cladding and drainage system.

The exact installation method depends on:

  • Wall construction
  • Window system
  • Door system
  • Building design
  • Flashing strategy
  • Waterproofing details
  • External finishes

There is no single installation detail that suits every building.

Why Correct Installation Matters

Installation is the connection between the window and the building.

Poor installation can contribute to:

  • Difficult operation
  • Water entry
  • Air leakage
  • Frame distortion
  • Poor drainage
  • Damaged finishes
  • Premature seal failure

The surrounding building envelope must work together with the window system.

Window Performance vs Building Performance

A window is only one component of the wall system.

Weather performance can depend on:

  • Window frame
  • Flashing
  • Sill detail
  • Wall wrap
  • Membranes
  • Sealants
  • Cladding
  • Paving
  • Drainage
  • Installation workmanship

A leak near a window does not automatically mean the window itself is the source.

Prepare the Opening Before Installation

Before installation, check that the opening is:

  • Correct size
  • Structurally suitable
  • Reasonably square
  • Reasonably level
  • Free from major obstructions

Any significant issue should be resolved before the frame is installed.

Check Final Window Dimensions

Confirm the actual window against the approved information.

Check:

  • Width
  • Height
  • Configuration
  • Colour
  • Glass
  • Opening direction
  • Quantity

Do not begin installation simply because the product has arrived on site.

Check the Opening Size

Compare the manufactured frame with the actual opening.

The opening should provide the intended installation clearance.

Excessively tight openings can make adjustment difficult.

Excessively large openings can create fixing and sealing problems.

Check Whether the Opening Is Square

Measure diagonally across the opening.

If the diagonal dimensions differ significantly, the opening may be out of square.

This should be considered before installation rather than forcing the aluminium frame to match the distortion.

Window Frames Should Not Be Forced Into Shape

Aluminium frames should generally be installed without twisting or distorting them.

Forcing a frame into an irregular opening can affect:

  • Sash operation
  • Sliding panels
  • Locks
  • Seals
  • Glass support

The frame should remain true.

Level

The sill or base of the window or door should be installed according to the required level condition.

For doors, this is especially important because poor level can affect:

  • Roller operation
  • Panel alignment
  • Locking
  • Drainage

Plumb

Vertical jambs should be correctly positioned.

Out-of-plumb installation can cause:

  • Doors to move unexpectedly
  • Locks to misalign
  • Sashes to bind

Square

The installed frame should remain square.

Checking diagonals during installation can help confirm this.

Support the Frame Properly

Frames should be adequately supported at appropriate locations.

The installation should avoid creating unsupported areas that allow the frame to:

  • Bow
  • Twist
  • Deflect

Support requirements depend on the particular frame and opening.

Packers and Shims

Packers or shims may be used to correctly position and support the frame.

They should be located appropriately and should not distort the aluminium profile.

Random or excessive packing can cause problems.

Fixing Aluminium Windows

Windows must be securely fixed to the surrounding building structure using an appropriate fixing method.

The correct fixing depends on:

  • Substrate
  • Frame system
  • Window size
  • Wind loads
  • Installation detail

Fixings should be compatible with both the aluminium frame and surrounding construction.

Avoid Over-Tightening Fixings

Over-tightened fixings can distort aluminium frames.

This can affect:

  • Sliding operation
  • Sash clearance
  • Locks
  • Weather seals

Fixings should secure the product without pulling the frame out of shape.

Fixing Into Timber Framing

When installing into timber framing, suitable fixings should engage with the appropriate structural framing.

The building frame should provide adequate support around the window opening.

Fixing Into Masonry

Masonry installations can require different fixing methods.

Consider:

  • Brick
  • Blockwork
  • Concrete
  • Existing openings

The fixing should suit the actual substrate.

Fixing Into Steel Framing

Steel-framed construction can require compatible fixing methods and careful coordination.

The installation should also consider material compatibility and separation where required.

Flashing Aluminium Windows

Flashing is a critical part of managing water around a window opening.

The flashing strategy should integrate with the building envelope.

Depending on the construction, flashing may include:

  • Sill flashing
  • Jamb flashing
  • Head flashing
  • Wall membranes
  • Cavity systems

What Does Window Flashing Do?

Flashing helps redirect water away from vulnerable junctions.

It is intended to work with the surrounding wall construction rather than operate as an isolated component.

Sill Flashing

Sill flashing helps manage water at the bottom of the opening.

It should integrate with:

  • Wall membrane
  • Cavity
  • External cladding
  • Drainage path

The actual detail depends on the building system.

Head Flashing

Head flashing can help prevent water running down the façade from entering behind the window.

Its design depends on:

  • Cladding
  • Wall construction
  • Window position

Jamb Flashing

Jamb details help manage water at the vertical sides of the window.

They should be coordinated with adjacent membranes and finishes.

Window Flashing Is Part of the Building Envelope

EZ Windows supplies and installs windows within the agreed scope.

Unless specifically included, the design of:

  • Building membranes
  • Wall waterproofing
  • Cavity systems
  • Cladding details
  • Structural openings

remains the responsibility of the relevant project parties.

Perimeter Sealing

The perimeter junction between the window and surrounding construction often requires sealing.

The sealant should be:

  • Suitable for the substrates
  • Applied correctly
  • Compatible with the joint
  • Able to accommodate expected movement

Sealant Is Not a Substitute for Correct Flashing

Applying more sealant does not necessarily correct a poorly designed building junction.

Good installation uses appropriate:

  • Flashing
  • Drainage
  • Joint design
  • Sealant

together.

Sealant Joint Width

Sealant requires an appropriate joint configuration to perform correctly.

An excessively thin smear may not provide the same performance as a properly formed joint.

The correct product and application should follow the relevant sealant supplier recommendations.

Backing Rod

Some perimeter joints may use backing rod to help control:

  • Sealant depth
  • Joint shape

Whether backing rod is required depends on the joint and sealant system.

Do Not Block Drainage Holes

Aluminium window and door systems can include designed drainage paths or weep holes.

These should not be blocked by:

  • Sealant
  • Render
  • Dirt
  • Paving
  • Construction debris

Blocking drainage can affect weather performance.

Window Weep Holes

Weep holes allow water entering certain frame cavities to drain to the exterior.

They are a normal part of many aluminium window systems.

They should remain clear after installation.

Window Sills and Drainage

External sill conditions should allow water to drain away from the opening.

Water should not be encouraged to pond against the frame.

Aluminium Door Thresholds

Door thresholds require particular attention.

They need to coordinate with:

  • Internal floor levels
  • External paving
  • Drainage
  • Waterproofing
  • Access requirements

Incorrect threshold coordination is a common source of site problems.

External Paving Levels

External paving should be considered before door installation is finalised.

If paving is brought too high against a door sill, it may affect:

  • Drainage
  • Weather performance
  • Clearances

The building design should establish the required relationship.

Balcony Doors

Doors opening onto balconies require coordinated design between:

  • Door threshold
  • Waterproof membrane
  • Balcony falls
  • Drainage
  • External finishes

The complete system must manage water.

Sliding Door Installation

Sliding doors need particularly accurate installation because the panels move on tracks or rollers.

The frame should remain:

  • Level
  • Square
  • Straight

Distortion can affect operation.

Sliding Door Sills

Sliding-door sill tracks should be properly supported.

Poor sill support can contribute to:

  • Track deflection
  • Roller problems
  • Misalignment

Stacker Door Installation

Stacker doors use multiple sliding panels.

Small installation errors can become more noticeable across several panels.

Check:

  • Frame level
  • Jamb alignment
  • Panel engagement
  • Lock operation

Bifold Door Installation

Bifold doors often place significant loads on the frame and hardware.

Installation should follow the requirements of the selected system.

Particular attention may be required to:

  • Head support
  • Threshold level
  • Frame alignment
  • Panel adjustment

Hinged Door Installation

Hinged aluminium doors should be installed so the frame remains square and the door leaf operates correctly.

Check:

  • Hinges
  • Lock alignment
  • Door clearances
  • Threshold

Awning Window Installation

Awning windows should be checked for:

  • Correct frame alignment
  • Smooth sash operation
  • Lock engagement
  • External opening clearance

If window shrouds are present, ensure the sash can open without interference.

Sliding Window Installation

Sliding windows rely on straight and level tracks.

Check that panels:

  • Slide freely
  • Engage correctly
  • Lock properly

Fixed Window Installation

Fixed windows contain no moving sash but still require correct:

  • Support
  • Fixing
  • Flashing
  • Sealing

Large fixed glazing may also require special handling.

Sashless Window Installation

Sashless systems require installation in accordance with the specific system requirements.

Because the glass itself forms much of the moving assembly, alignment is particularly important.

Replacement Window Installation

Replacement projects often require more preparation than new construction.

Existing windows may need to be removed from:

  • Brick
  • Timber
  • Render
  • Cladding

The condition left behind can vary significantly.

Full-Frame Replacement

Full-frame replacement involves removing the existing window frame and installing a new unit into the resulting opening.

This can allow:

  • Greater design flexibility
  • Larger glass areas
  • New frame systems

However, it may involve more surrounding building work.

Insert or Retrofit Installation

Some replacement windows may be installed within an existing frame or opening arrangement.

This can reduce disturbance but may:

  • Reduce visible glass area
  • Retain parts of the old frame

The suitability depends on the project.

Removing Old Timber Windows

Older timber windows may be integrated with:

  • Reveals
  • Architraves
  • External trims
  • Flashings

Removing them can expose previously hidden building conditions.

Removing Old Aluminium Windows

Existing aluminium frames may have:

  • Nail fins
  • Subframes
  • Brick fixings
  • Sealed perimeter joints

The removal method should be planned before the replacement is ordered.

Removing Steel Windows

Steel windows can be embedded into masonry and may require specialist removal.

This can cause damage to surrounding finishes if not carefully managed.

Unexpected Conditions During Replacement

Once an old window is removed, previously hidden issues may become visible.

These can include:

  • Rot
  • Corrosion
  • Water damage
  • Failed flashing
  • Damaged framing

These building defects may require separate rectification.

Replacement Window Making Good

Replacement work may involve making good around:

  • Plaster
  • Render
  • Brick
  • Paint
  • Architraves
  • Cladding

The scope should clearly identify which works are included.

Internal Architraves

New or existing architraves may be required to finish the internal perimeter.

This depends on the wall and installation detail.

External Trims

External trims may sometimes be used where appropriate to provide a neat finish.

They should not be relied upon to conceal major installation defects.

Aluminium Window Installation in Brick

Brick construction can involve:

  • Brick veneer
  • Double brick
  • Masonry openings

The correct flashing and fixing detail depends on the wall system.

Aluminium Window Installation in Lightweight Cladding

Lightweight walls may use:

  • Weatherboard
  • Fibre cement
  • Metal cladding
  • Composite cladding

The window installation must coordinate with the building wrap and cladding system.

Aluminium Window Installation in Render

Rendered systems need careful perimeter detailing.

Render should not interfere with:

  • Drainage paths
  • Window operation
  • Required sealant joints

Aluminium Window Installation in Concrete

Concrete openings require appropriate fixing and sealing methods.

Opening tolerances and surface condition should be checked before installation.

Window Position in the Wall

The depth at which the window sits within the wall can affect:

  • Appearance
  • Flashing
  • Reveal depth
  • Shading

The intended frame position should be established before installation.

Flush vs Recessed Windows

Some architectural designs position windows:

  • Flush with cladding
  • Recessed into the façade

The detail affects both appearance and weatherproofing strategy.

Aluminium Window Shrouds and Installation

Window shrouds should be coordinated with the installed window position.

They can affect:

  • Frame access
  • Sash clearance
  • Sealant access
  • Visual alignment

Where awning windows are used, sufficient clearance is required for the sash to open.

Window Shroud Fixing

Unless specifically included in the EZ Windows installation scope, shroud fixing may remain the builder’s responsibility.

The approved shroud detail should be followed.

Installing Large Aluminium Windows

Large windows can require:

  • Additional labour
  • Vacuum lifters
  • Crane assistance
  • Special transport

The installation method should be planned before the glass or complete unit arrives.

Glass Handling

Glass should be handled carefully to avoid:

  • Edge damage
  • Scratches
  • Impact

Large glass should be moved using suitable equipment and safe handling procedures.

Do Not Lift Windows by Hardware

Frames should not be handled in ways that place inappropriate loads on:

  • Handles
  • Locks
  • Sashes
  • Hardware

Use suitable lifting points and methods.

Protect Powder-Coated Frames

Powder-coated aluminium can be damaged during construction.

Protect frames from:

  • Grinding sparks
  • Welding
  • Cement
  • Mortar
  • Render
  • Paint
  • Abrasive tools

Remove Construction Contamination Promptly

Construction materials left on finished aluminium can damage or stain the surface.

Appropriate cleaning should be performed promptly using suitable methods.

Do Not Use Harsh Cleaning Products

Avoid products that can attack the powder-coated finish.

Follow the coating manufacturer’s maintenance recommendations.

Protect Glass During Construction

Glass can be scratched by:

  • Cement particles
  • Metal fragments
  • Abrasive cleaning

Care should be taken throughout remaining building work.

Window Adjustment After Installation

Operable windows may require final adjustment.

This can include:

  • Locks
  • Rollers
  • Sashes
  • Hinges

The frame should be correctly installed before attempting to compensate with hardware adjustment.

Door Roller Adjustment

Sliding doors may allow roller adjustment to improve panel alignment.

Adjustment should not be used to compensate for a severely out-of-level frame.

Lock Adjustment

Locks and keepers may require minor adjustment after installation.

The door or sash should close smoothly without excessive force.

Flyscreen Installation

Flyscreens should be fitted to the appropriate window system and checked for:

  • Correct fit
  • Smooth operation
  • Easy removal where applicable

Security Screen Installation

Security-screen installation should follow the requirements of the selected screen system.

A standard flyscreen should not be confused with a security screen.

Retractable Screen Installation

Retractable screens require suitable clearances and alignment.

They should be coordinated with the door system before final installation.

Installation of Double-Glazed Windows

Double-glazed windows are generally heavier than equivalent basic single-glazed windows.

Handling and support should account for:

  • Unit weight
  • Frame size
  • Glass size

Installation of Thermally Broken Windows

Thermally broken windows should be installed in a way that preserves the intended frame configuration.

The surrounding building junction can still create thermal bridging if poorly designed.

Thermal Performance and Installation

High-performance glass alone cannot compensate for major gaps around the window.

The perimeter connection should be appropriately sealed and integrated into the building envelope.

Acoustic Performance and Installation

Acoustic windows rely heavily on:

  • Seals
  • Frame alignment
  • Perimeter sealing

Small gaps can significantly reduce acoustic performance.

Installation and Condensation

Correct installation can reduce unwanted air leakage and thermal bridging at the window perimeter.

However, condensation can still occur depending on:

  • Indoor humidity
  • External temperature
  • Ventilation
  • Building insulation

Installation cannot guarantee complete elimination of condensation.

Water Resistance

Aluminium windows and doors are designed to provide weather performance appropriate to the selected system and application.

They should not be described as completely waterproof under all possible conditions.

Water management depends on:

  • Frame
  • Drainage
  • Flashing
  • Surrounding construction
  • Installation

Wind-Driven Rain

Severe wind-driven rain places greater pressure on windows and doors.

Correct frame selection and installation are therefore important in exposed locations.

Open Windows and Rain

An open window can admit rain, particularly under windy conditions.

This is not necessarily a failure of the product.

Door Threshold Water

Water near a door threshold does not automatically mean the door itself is leaking.

Potential sources include:

  • External paving
  • Balcony waterproofing
  • Wall junctions
  • Flashing
  • Surrounding cladding
  • Drainage

The complete building condition should be investigated.

Final Installation Inspection

After installation, check:

  • Frame alignment
  • Locks
  • Sash operation
  • Sliding operation
  • Drainage openings
  • Sealant
  • Glass
  • Powder coating

Any obvious issue should be addressed before handover.

Clean the Tracks

Tracks can collect:

  • Building dust
  • Metal fragments
  • Plaster
  • Dirt

Tracks should be cleaned before final operation.

Check Weep Holes

Ensure that drainage openings remain clear after:

  • Sealing
  • Render
  • Painting
  • Cleaning

Check Door Operation

Every door should be opened and closed several times.

Check:

  • Rollers
  • Hinges
  • Locks
  • Handles

Check Window Operation

Test every opening sash.

Check:

  • Handles
  • Locks
  • Friction stays or relevant hardware
  • Clearances

Handover

At handover, the customer or builder should be made aware of basic:

  • Operation
  • Cleaning
  • Maintenance

requirements.

Maintenance After Installation

Ongoing maintenance can include:

  • Cleaning frames
  • Cleaning tracks
  • Clearing drainage
  • Inspecting seals
  • Maintaining hardware

The required frequency depends on the environment.

Coastal Installation and Maintenance

Coastal locations can require more frequent cleaning because of salt exposure.

The coating system and maintenance programme should suit the actual project environment.

Installation by Builders

Builders may install supply-only aluminium windows using their own trades.

In this situation, they are responsible for ensuring the installation is appropriate to:

  • Product
  • Opening
  • Building envelope

unless another scope has been agreed.

Installation by Subcontractors

Where installation is carried out by a subcontractor, the agreed responsibilities should be clear.

This can include:

  • Removal
  • Installation
  • Sealing
  • Trims
  • Making good

Installation Scope Should Be Written Clearly

A quotation should identify whether it includes:

  • Supply only
  • Delivery
  • Removal of existing windows
  • Installation
  • Sealant
  • Trims
  • Making good
  • Screens

This prevents assumptions.

Installation Warranty

Where installation is carried out by EZ Windows within the agreed scope, EZ Windows generally provides a 1-year installation warranty, subject to applicable written terms, exclusions and project conditions.

This is separate from any applicable product or component warranty.

What Installation Warranty Does Not Automatically Cover

An installation warranty should not automatically be assumed to cover unrelated building elements such as:

  • Roof leaks
  • Wall leaks
  • Failed membranes
  • Balcony waterproofing
  • External paving
  • Drainage
  • Structural movement

The cause of an issue should be properly identified.

Product Warranty vs Installation Warranty

These are different.

A product warranty relates to the supplied window or door product.

An installation warranty relates to the installation workmanship within the agreed scope.

Third-party components can also have their own manufacturer warranty terms.

Who Is Responsible for Building Design?

Unless specifically included in the agreed scope, EZ Windows does not act as the:

  • Architect
  • Structural engineer
  • Façade engineer
  • Waterproofing consultant
  • Building surveyor

The relevant project professionals remain responsible for their respective design and approval roles.

Who Is Responsible for Structural Openings?

The surrounding building structure should be designed and constructed to support the window or door.

This may include:

  • Lintels
  • Structural framing
  • Steelwork

These items are not automatically part of the window supplier’s scope.

Who Is Responsible for Waterproofing?

The complete building waterproofing strategy should be coordinated by the responsible project parties.

Window perimeter sealing is only one part of that system.

Window Installation for Architects

Architects should consider installation details during design rather than leaving them until site.

Important details include:

  • Frame position
  • Flashing
  • Cladding junctions
  • Sills
  • Shrouds
  • Thresholds

Window Installation for Builders

Builders should coordinate the window package with:

  • Framing
  • Brickwork
  • Cladding
  • Waterproofing
  • Internal finishes
  • External paving

Early coordination can reduce site rework.

Window Installation for Renovators

Renovations can expose unexpected conditions.

Allow contingency for:

  • Damaged timber
  • Failed flashing
  • Irregular openings
  • Making good

Older buildings rarely provide perfectly predictable openings.

Window Installation for New Homes

New homes provide the opportunity to coordinate window installation from the design stage.

This can improve:

  • Opening preparation
  • Flashing
  • Alignment
  • External finishes

Window Installation for Commercial Projects

Commercial projects may require:

  • Larger crews
  • Staged installation
  • Access equipment
  • Site safety systems
  • Crane or lifting plans

Programme coordination is especially important.

Common Aluminium Window Installation Mistakes

Common problems include:

  • Installing into an incorrect opening
  • Frame installed out of square
  • Frame installed out of level
  • Over-tightening fixings
  • Poor sill support
  • Blocked drainage
  • Inadequate flashing
  • Poor perimeter sealing
  • Paving too high against door sills
  • Damage from later trades

Should Aluminium Windows Be Installed by a Professional?

For complex, replacement, large or performance-sensitive work, experienced installation is strongly recommended.

Window installation affects much more than appearance.

It forms part of the building envelope.

Can Homeowners Install Their Own Windows?

Supply-only products can be installed by others, but the installer assumes responsibility for correct installation within their scope.

Customers should ensure the installer understands the particular frame and building system.

Can Windows Be Installed Before Cladding?

Depending on the construction system, windows are often installed at a stage that allows flashing and cladding to integrate correctly.

The sequence should follow the building’s designed construction method.

Can Windows Be Installed After Cladding?

Some replacement or specialised installations can occur after cladding, but the perimeter detail must still be properly managed.

Can Windows Be Installed in Rain?

Installation should not proceed where weather creates:

  • Unsafe conditions
  • Inability to complete sealing
  • Risk of water entering the building

Weather can therefore affect installation scheduling.

How Long Does Window Installation Take?

There is no universal installation time.

It depends on:

  • Number of windows
  • Size
  • Existing conditions
  • Access
  • Removal
  • Making good

A single replacement window and an entire commercial façade require very different programmes.

Does Installation Affect Price?

Yes.

Installation cost can be influenced by:

  • Product size
  • Building height
  • Removal
  • Access
  • Cranes
  • Scaffolding
  • Making good
  • Site location

Frequently Asked Questions About Aluminium Window and Door Installation

How are aluminium windows installed?

They are positioned in a suitable opening, aligned, supported, fixed, flashed and sealed according to the relevant product and building detail.

Should aluminium windows be installed level?

Yes. Correct level, plumb and squareness are important for operation and performance.

Do aluminium windows need flashing?

The building opening should incorporate appropriate water-management detailing. The actual flashing design depends on the construction system.

Does sealant make a window waterproof?

Sealant is one part of the junction. It does not replace proper flashing and drainage.

Should window weep holes be sealed?

No. Designed drainage openings should remain clear.

How much gap should be left around an aluminium window?

There is no universal gap for every installation. Clearance depends on the product and building detail.

Can aluminium windows be screwed directly into timber?

Appropriate fixings can be used into suitable structural framing, subject to the system and project requirements.
