Aluminium Window Shroud Specifications

Aluminium Window Shroud Specifications for Australian Architectural Projects

Aluminium window shroud specifications provide architects, designers, builders, engineers and developers with the information required to incorporate architectural shroud systems into project documentation.

EZ Windows manufactures custom aluminium window shrouds for Australian residential, commercial, education, multi-residential and architectural projects.

Our architectural window shrouds are available in welded and modular configurations and can be developed to suit project-specific window dimensions, façade requirements, projections, finishes and installation conditions.

This specification guide is designed to assist architects and designers during concept design, documentation, tendering and construction. Final product dimensions, fixing requirements and performance requirements should be confirmed against the approved project documentation.

Aluminium Window Shroud Specification Overview

An aluminium window shroud specification should clearly establish the required:

  • Product
  • Material
  • Construction
  • Dimensions
  • Finish
  • Fixing
  • Installation
  • Interfaces
  • Documentation
  • Quality requirements

The specification should be coordinated with the architectural drawings, window schedule, façade documentation and relevant engineering requirements.
