Planning and installation

This page is an early-stage guide, not a supplier quotation or final design. The installed solution should be coordinated with the building layout, services and relevant professional requirements.

Before you commit

• Confirm falls, edge details, weather exposure and the structural design for any elevated or suspended work.
• Confirm the final product, specification, installation scope, lead time and warranty directly with the supplier or installer.
