Question
The corners of my Genesis tiles are not resting flush in the grid. OR Why do shadow lines appear in the corners of my Genesis ceiling tiles?Answer
If your Genesis ceiling tile appears to sit higher on the ceiling grid corners, it is likely because of the type of ceiling grid you are using. There are two main types of ceiling grid systems: a “stab” system, and a “hook” system. A stab grid system provides additional stability as the cross-tee overlaps the main beam to prevent twisting. This feature often qualifies stab systems for a Seismic Rating. A hook grid system is often a lighter-duty grid. See images below.
