APPEARANCE AND QUALITY CONTROL / FIELD NOTE 22
Panel Flatness vs Installed Facade Appearance
Flatness measured on a panel and the appearance of the installed facade are related but different checks. The subframe, joint alignment, finish and grazing light affect the installed impression.
What to check on your project
Agree on the measurement condition, datum and inspection location for panel flatness. Review a representative installation sample with actual supports, joints and orientation under agreed viewing conditions before approving mass production.
