The spacing between main tees (the primary runners that run the length of the ceiling) is commonly 4 feet apart when installed in a rectangular grid configuration. The cross tees, which connect the main tees and create the grid layout, are generally found in lengths of 2 feet and 4 feet, allowing for flexibility in design and installation.

Importance of Access Hatches
Another notable feature of fibre ceiling sheets is their acoustic properties. Many types are designed to absorb sound and minimize reverberation, making them ideal for spaces where noise reduction is critical, such as offices, conference rooms, and auditoriums. The ability to enhance the acoustics of a room while still providing aesthetic appeal is one of the key reasons for their growing popularity in interior design.

Another benefit of using ceiling grid main tees is the potential for easy access to the plenum space above the ceiling. In many buildings, this hidden area contains vital mechanical, electrical, and plumbing systems. The grid system allows for the easy removal of tiles to access these components for maintenance or upgrades without disturbing the entire ceiling.
