Commercial Aluminium Windows and Doors

Commercial Aluminium Windows and Doors

Commercial aluminium windows and doors are used across offices, schools, apartments, government buildings, retail developments and other commercial projects where durability, architectural appearance and project-specific performance are important.

Compared with a simple residential window package, commercial projects can involve more demanding requirements relating to:

  • Window size
  • Glass weight
  • Wind pressure
  • Energy performance
  • Acoustic performance
  • Safety glazing
  • Accessibility
  • Façade integration
  • Hardware
  • Installation
  • Project documentation

The correct commercial aluminium windows and doors should therefore be selected around the complete project specification rather than appearance alone.

EZ Windows supplies aluminium windows and doors for commercial, institutional, multi-residential and architectural projects according to the approved scope and project requirements.

What Are Commercial Aluminium Windows and Doors?

Commercial aluminium windows and doors are aluminium-framed systems used in non-residential and larger-scale building projects where strength, durability, glazing capacity and project-specific performance are required.

Applications can include:

  • Offices
  • Schools
  • Universities
  • Childcare centres
  • Government buildings
  • Apartments
  • Multi-residential developments
  • Retail buildings
  • Medical facilities
  • Community buildings
  • Mixed-use developments

  • Integration with façade systems

The actual suitability of a system depends on the approved project requirements.

Commercial Aluminium Window Types

Commercial projects can use a combination of window types depending on the building function and architectural design.

Common configurations include:

  • Fixed windows
  • Awning windows
  • Sliding windows
  • Combination windows
  • High-level glazing
  • Feature glazing
  • Shopfront-style framing where appropriate
  • Custom architectural glazing

Different parts of the same building may require different systems.

Commercial Aluminium Fixed Windows

Fixed windows are widely used in commercial architecture because they can provide substantial areas of glazing without requiring moving sashes.

Applications can include:

  • Offices
  • Schools
  • Stairwells
  • Corridors
  • Lobbies
  • Meeting rooms
  • Apartment façades
  • Commercial frontages

Fixed windows can also be combined with operable windows for ventilation.

Their simplicity can make them particularly useful where thermal or acoustic performance is important.

Commercial Aluminium Awning Windows

Awning windows are commonly used where controlled natural ventilation is required.

They can be suitable for:

  • Offices
  • Classrooms
  • Amenities
  • Apartments
  • Staff areas
  • Community buildings

Their suitability depends on:

  • Window size
  • Hardware
  • Opening clearance
  • Wind exposure
  • Glass weight

Where external shrouds or façade features are used, sufficient opening clearance must be coordinated.

Commercial Aluminium Sliding Windows

Sliding windows can provide a practical solution where projecting sashes are not desirable.

They may be appropriate in:

  • Apartments
  • Offices
  • Education buildings
  • Multi-residential projects

Acoustic, air-leakage and thermal requirements should be considered when selecting the system.

Commercial Aluminium Doors

Commercial aluminium doors can be used for a range of building access requirements.

Depending on the project, configurations may include:

  • Security
  • Thresholds
  • Maintenance

Commercial Aluminium Hinged Doors

Hinged aluminium doors can provide robust access for many commercial applications.

They can be used in:

  • Offices
  • Schools
  • Community buildings
  • Commercial entrances
  • Amenities
  • Internal courtyards

Hardware selection becomes particularly important in high-use environments.

Commercial Aluminium Sliding Doors

Sliding doors can provide wide glazed openings while limiting the floor space required for door swing.

Applications can include:

  • Apartment developments
  • Offices
  • Community buildings
  • Commercial terraces
  • Education facilities

Large commercial sliding doors require careful consideration of:

  • Panel size
  • Glass weight
  • Roller capacity
  • Hardware
  • Track design
  • Thresholds
  • Drainage

Aluminium Windows for Offices

Office windows need to balance multiple requirements.

These can include:

  • Natural light
  • Views
  • Energy efficiency
  • Acoustic performance
  • Ventilation
  • Glare control
  • Architectural appearance

Large areas of glazing can improve amenity but can also influence heating, cooling and solar gain.

The glass and frame should therefore be selected as a complete system.

Aluminium Windows for Schools

Education buildings can place significant demands on windows and doors.

Considerations may include:

  • Durability
  • Ventilation
  • Safety glazing
  • Acoustic performance
  • Energy performance
  • Security
  • High-use hardware
  • Maintenance

Schools near busy roads, airports or other noise sources may require acoustic glazing.

Windows should be coordinated with the approved architectural and consultant documentation.

Aluminium Windows for Universities

University projects can combine education, administration, accommodation and public spaces.

This can create varied window and door requirements throughout the same development.

Applications may include:

  • Teaching rooms
  • Offices
  • Libraries
  • Laboratories
  • Student accommodation
  • Common areas

Each area may require a different balance of ventilation, acoustics, safety, thermal performance and access.

Aluminium Windows for Childcare Centres

Childcare projects require careful coordination of window placement, glazing and access.

Considerations may include:

  • Safety glazing
  • Ventilation
  • Natural light
  • Acoustic control
  • Security
  • Privacy
  • Window operation

Standard flyscreens should not be treated as fall-prevention or security devices unless they are specifically designed and approved for that purpose.

Aluminium Windows for Government Buildings

Government and public-sector buildings can involve detailed project documentation and defined performance requirements.

These may include:

  • Energy targets
  • Acoustic requirements
  • Security
  • Accessibility
  • Safety glazing
  • Durability
  • Documentation
  • Maintenance

Window and door selection should correspond with the approved specification and relevant project requirements.

Aluminium Windows for Apartments

Apartment buildings can require careful consideration of:

  • Wind pressure
  • Acoustic performance
  • Energy efficiency
  • Water resistance
  • Safety glazing
  • Fall prevention
  • Screens
  • Balcony doors
  • Access

Different elevations may also experience different levels of exposure.

The same window configuration may therefore not be appropriate throughout the entire building.

Aluminium Windows for Multi-Residential Projects

Multi-residential projects often require repetition and efficiency while still meeting defined architectural and performance requirements.

Important considerations include:

  • Standardised sizes
  • Consistent finishes
  • Glazing
  • Acoustic performance
  • Energy performance
  • Installation sequencing
  • Access
  • Delivery logistics

Early coordination can improve construction efficiency.

Aluminium Windows for Retail Buildings

Retail projects can use aluminium windows and doors for:

  • Shopfront-style glazing
  • Entry doors
  • Fixed glazing
  • Internal tenancy glazing
  • Feature façades

The required system depends on whether the opening forms part of the external building envelope or internal commercial fitout.

Aluminium Windows for Medical and Healthcare Buildings

Healthcare projects can have additional requirements relating to:

  • Acoustic privacy
  • Safety
  • Cleaning
  • Ventilation
  • Accessibility
  • Durability

Any defined project requirements should be incorporated into the approved window and door specification.

Commercial Double-Glazed Aluminium Windows

Double glazing can be used in commercial projects where improved thermal or acoustic performance is required.

A double-glazed unit generally consists of two glass panes separated by a sealed cavity.

Performance depends on:

  • Glass specification
  • Cavity
  • Spacer
  • Coatings
  • Frame
  • Seals
  • Installation

Double glazing alone should not be treated as a complete performance solution.

Commercial Thermally Broken Aluminium Windows

Thermally broken aluminium systems reduce direct conductive heat transfer through the aluminium frame.

They may be relevant to commercial projects where improved whole-window thermal performance is required.

They are often considered alongside:

  • Double glazing
  • Low-E glass
  • Energy modelling
  • High-performance façades

Thermally broken framing does not eliminate all heat transfer or condensation.

Energy-Efficient Commercial Aluminium Windows

Energy performance is increasingly important in commercial buildings.

Window performance can affect:

  • Heating demand
  • Cooling demand
  • Internal comfort
  • Solar gain
  • Mechanical-system loads

Important considerations include:

  • Whole-window U-value
  • Solar heat gain
  • Frame performance
  • Glass
  • Orientation
  • Shading
  • Window-to-wall ratio
  • Air leakage

Where the project has specific energy requirements, the selected windows should align with the approved assessment.

Acoustic Commercial Aluminium Windows

Acoustic requirements can be particularly important in:

  • Schools
  • Offices
  • Apartments
  • Hotels
  • Medical buildings
  • Buildings near transport corridors

Acoustic performance depends on:

  • Glass thickness
  • Laminated glass
  • Acoustic laminates
  • Frame
  • Seals
  • Opening type
  • Installation

Double glazing alone does not automatically guarantee the required acoustic performance.

Commercial Window Glass Options

Commercial glazing can vary significantly according to project requirements.

Possible glass types include:

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

Glass selection must suit the particular application.

Safety Glass

Commercial projects may require safety glazing in specified locations.

The actual requirement depends on the opening, use, size, location and applicable project documentation.

Safety glass should therefore be established before manufacture.

Low-E Glass for Commercial Windows

Low-E glass can be used to modify radiant heat transfer through the glazing.

Depending on the product and project, it can contribute to improved thermal performance.

The correct Low-E coating should be selected according to the building’s energy and solar requirements.

Solar-Control Glass

Solar-control glazing can help manage unwanted solar heat gain.

It may be particularly relevant to highly glazed commercial buildings.

The appropriate specification depends on:

  • Orientation
  • Climate
  • Building design
  • Shading
  • Internal use

A glass type that performs well on one elevation may not necessarily be ideal for another.

Commercial Window Orientation

Orientation has a major impact on solar exposure.

Different façades can receive substantially different levels of sunlight.

This means window and glass specifications may need to vary across:

  • North elevations
  • East elevations
  • West elevations
  • South elevations

West-facing glazing can be especially important because of afternoon solar exposure.

External Shading for Commercial Buildings

External shading can help reduce direct solar exposure before it reaches the glass.

Shading elements can include:

  • Aluminium window shrouds
  • Sunhoods
  • Screens
  • Louvres
  • Architectural projections

The actual effectiveness depends on orientation and geometry.

Commercial Aluminium Window Shrouds

Window shrouds can provide an architectural feature while also contributing to shading.

Commercial applications can include:

  • Schools
  • Offices
  • Apartments
  • Government buildings
  • Community buildings

Shrouds can create:

  • Façade depth
  • Shadow
  • Rhythm
  • Feature colour
  • Visual framing

Where awning windows are used inside shrouds, opening clearance must be coordinated.

Commercial Privacy and Batten Screens

Aluminium screens and battens can be used to provide:

  • Privacy
  • Solar control
  • Architectural texture
  • Screening of services
  • Feature elements

They can be coordinated with window systems as part of the façade design.

Powder-Coated Commercial Aluminium Windows

Powder coating provides a broad selection of architectural finishes.

Colours can be coordinated with:

  • Cladding
  • Roofing
  • Render
  • Curtain-wall elements
  • Window shrouds
  • Screens
  • Other aluminium components

The actual coating specification should suit the project environment.

Powder-Coat Warranty

Powder-coat warranty depends on the actual system selected and applied.

Important factors include:

  • Powder manufacturer
  • Product range
  • Exposure
  • Coastal environment
  • Industrial environment
  • Cleaning
  • Maintenance
  • Installation

Colour alone does not determine the applicable finish warranty.

Commercial Window Sizes

There is no universal maximum size that applies to every aluminium window.

Maximum practical dimensions depend on:

  • Frame system
  • Glass
  • Wind pressure
  • Building height
  • Hardware
  • Configuration
  • Structural requirements

Large windows may require additional framing or alternative systems.

Large Commercial Glass Panels

Large glazing can create a strong architectural effect but also introduces practical challenges.

These can include:

  • Glass weight
  • Transport
  • Crane access
  • Vacuum lifting
  • Site access
  • Installation
  • Replacement

These factors should be considered before finalising large glass dimensions.

Commercial Window Wind Pressure

Commercial buildings may experience higher wind pressures than low-rise residential buildings.

This is particularly relevant to:

  • Tall buildings
  • Exposed sites
  • Coastal areas
  • Large windows
  • High-level glazing

The required performance should be established according to the project requirements and relevant engineering.

Commercial Window Shop Drawings

Shop drawings can form an important part of the commercial window process.

They may show:

  • Window dimensions
  • Door dimensions
  • Mullions
  • Transoms
  • Opening types
  • Glass
  • Hardware
  • Configurations

Where shop drawings are required, they should be reviewed and approved by the responsible party before manufacture.

Approval confirms the manufacturing information, not professional design certification unless specifically included.

Commercial Window Scheduling

A clear window schedule can improve estimating, manufacturing and installation.

Useful information includes:

  • Window number
  • Location
  • Size
  • Type
  • Glass
  • Colour
  • Hardware
