Aluminium Window Shroud Specifications
Aluminium Window Shroud Specifications for Architects, Designers and Builders
Aluminium window shroud specifications provide architects, building designers, builders and developers with the information required to incorporate architectural shroud systems into project documentation.
A properly documented architectural window shroud specification establishes the intended material, construction method, dimensions, finish, performance requirements, documentation and installation coordination for the project.
EZ Windows designs and manufactures custom aluminium window shrouds for Australian residential, commercial, education, multi-residential and architectural projects. Our systems can be developed as welded or modular assemblies according to the requirements of the project.
This guide provides a framework for specifying custom aluminium window shrouds, including product description, material, finish, construction, shop drawings, installation and coordination requirements.
For project-specific requirements, the approved drawings, engineering documentation and project specifications should always take precedence over generic information.
What Should an Aluminium Window Shroud Specification Include?
A complete specification should clearly identify:
- Product type
- Material
- Construction method
- Dimensions
- Projection
- Finish
- Colour
- Fixing
- Interfaces
- Shop drawings
- Installation
- Quality requirements
- Relevant project documentation
Clear specification reduces ambiguity between the architect, builder, manufacturer and installer.
Aluminium Window Shroud Product Description
A typical specification description may identify the product as:
Custom architectural aluminium window shroud designed to provide an external architectural surround to window and glazed openings.
The system may be manufactured as:
- Welded aluminium construction
- Modular aluminium construction
The selected construction method should be identified within the project documentation.
Aluminium Window Shroud Material
The shroud should be manufactured from aluminium suitable for the intended application.
The specification should identify the required:
- Aluminium grade
- Material thickness
- Fabrication requirements
- Structural requirements
- Environmental exposure
Material selection should be confirmed against the project’s engineering and performance requirements.
Welded Aluminium Shroud Specification
A welded shroud is fabricated into a substantially complete architectural assembly.
A specification may identify:
Construction: Fabricated aluminium frame with welded corners and joints as required by the approved shop drawings.
Welded construction may be particularly appropriate where:
- Premium appearance is required
- Corner presentation is important
- Feature windows are involved
- Complete factory fabrication is preferred
Modular Aluminium Shroud Specification
A modular shroud consists of separate components assembled during installation.
A specification may identify:
Construction: Modular aluminium window shroud system consisting of project-specific components assembled and fixed in accordance with approved shop drawings.
Modular construction may be particularly suitable where:
- Transport access is restricted
- Components are large
- Site handling is important
- Multiple shrouds are required
Aluminium Window Shroud Dimensions
Dimensions should be project-specific.
The specification and drawings should establish:
- Overall width
- Overall height
- Projection
- Face width
- Returns
- Internal opening
- Corner configuration
Dimensions should be coordinated with the window schedule and architectural elevations.
Window-to-Shroud Clearance
The relationship between the window and shroud should be clearly established.
A common design consideration is approximately 10 mm clearance between the window dimensions and the internal shroud dimensions, subject to the approved project requirements.
Where fixing lugs or other components affect the available internal clearance, these must be included in the coordination process.
The final dimensions must be confirmed by the approved shop drawings.
Aluminium Window Shroud Projection
Projection should be documented because it directly affects:
- Façade depth
- Shadow
- Appearance
- Installation
- Fixing
- Material quantities
The projection should be coordinated with the architectural elevations and sections.
Aluminium Window Shroud Finish
The specification should identify the required external finish.
For powder coated aluminium, specify:
- Colour
- Finish
- Coating system
- Applicable quality requirements
The selected finish should be appropriate for the project’s environmental conditions.
Colour Coordination
The aluminium shroud may be:
Matched to Windows
Creating a consistent façade appearance.
Contrasted With Windows
Creating a deliberate architectural feature.
Coordinated With Other Aluminium
For example:
- Doors
- Screens
- Fascias
- Other architectural elements
The final colour should be confirmed during the project approval process.
Aluminium Window Shroud Shop Drawings
Shop drawings are an important part of the specification process.
The manufacturer should provide project-specific drawings showing, where applicable:
- Overall dimensions
- Component dimensions
- Projection
- Internal opening
- Corner details
- Fixing locations
- Joining details
- Window relationship
- Façade interfaces
Shop drawings should be reviewed and approved before manufacturing.
Architectural Window Shroud Documentation
A project documentation package may include:
- Product information
- Technical data
- Shop drawings
- Installation information
- Finish information
- Warranty documentation
- Maintenance information
- Relevant compliance documentation

Aluminium Window Shroud Fixing
Fixing requirements depend on:
- Shroud dimensions
- Shroud weight
- Wall construction
- Substrate
- Projection
- Structural loads
- Wind conditions
- Engineering requirements
The specification should require the shroud to be securely fixed to an appropriate substrate using fixings suitable for the project.
Specific fixing details should be confirmed through the approved drawings and engineering documentation.
Structural Considerations
Large or heavily projecting shrouds may require structural consideration.
The project team should assess relevant:
- Wind loads
- Dead loads
- Support conditions
- Fixing capacity
- Substrate
- Building movement
The shroud should not be assumed to provide structural support to the building or window unless specifically designed and documented for that purpose.
Waterproofing Coordination
External shrouds must be coordinated with the building envelope.
The specification should require coordination with:
- Window systems
- Flashings
- Membranes
- Sealants
- Drainage
- Cladding
- Wall construction
The shroud should not compromise the intended waterproofing or drainage strategy.
Aluminium Window Shroud Installation
Installation should be undertaken in accordance with:
- Approved shop drawings
- Project specifications
- Fixing details
- Engineering requirements
- Manufacturer information
The installer should confirm:
- Correct location
- Correct orientation
- Level
- Plumb
- Projection
- Alignment
- Fixing
- Interfaces
Refer to the:
Aluminium Window Shroud Installation Guide
for additional installation considerations.
Protection of Finished Shrouds
Finished aluminium shrouds should be protected from damage during construction.
Protection should minimise exposure to:
- Scratches
- Cement
- Mortar
- Render
- Concrete
- Abrasive materials
- Metal swarf
- Other construction contamination
Protection should remain in place until the relevant construction activities are complete.
Aluminium Window Shroud Quality Requirements
The completed product should be:
- Free from significant visible defects
