What is of least importance in selecting ceiling tiles?

When selecting ceiling tiles, unit weight is generally of least importance compared to the other factors listed. While the weight of ceiling tiles can affect certain aspects, such as structural load or installation methods, it does not significantly influence the aesthetic appeal, functionality, or overall performance of the ceiling.

Color plays a crucial role in interior design and can dramatically affect the ambiance of a space. Insulation properties are essential for soundproofing and thermal efficiency within a building, ensuring comfort and energy efficiency. Maintenance requirements are also vital as they impact the long-term upkeep and cost-effectiveness of the ceiling system. These aspects are crucial for functionality, aesthetic coherence, and sustainability, making them much more significant than the unit weight when selecting ceiling tiles.
