Review the current technical data, installation instructions, drawings, samples, finish information, and any project-required reports for the exact profile. Do not transfer documentation from decking, another cladding profile, or a visually similar product.
Performance requirements
If the project requires specific fire, wind, structural, UV, weathering, code, or certification documentation, request the exact current report applicable to the selected product and configuration before specifying the requirement as satisfied.
Sample and approval process
For significant projects, consider reviewing a physical sample, finish board, or mockup before final material release. Confirm color, texture, profile, joint appearance, trim conditions, and installation orientation.
