Focusing on "Dealing with Mold: How Moisture-Resistant Boards Protect Your Interior.", this article breaks it down one by one from the four levels of design basis, material matching, construction control and acceptance evidence, and provides parameters, practices and checklists that can be directly implemented for the design, procurement, construction and supervision teams to compare and implement.

1. Determine the system first, then the materials

The selection sequence of ceilings and partitions should be: use function → system structure → plates and keels → accessories and auxiliary materials. Selecting panels first and then working backwards on the system often results in mismatch in load, fire protection and sound insulation indicators.

2. Matching of plates and usage conditions

3. Keel and accessories

The keel specifications should be determined according to the floor height, span and load, and the accessories (hanging parts, connectors, support cards) must be matched with the keel system. Mixing accessories from different manufacturers can easily cause gaps in fit and insufficient load-bearing capacity, making it difficult to rectify after concealment.

4. Selection checklist

• Check whether the fire protection, sound insulation, moisture-proof and environmental protection indicators meet the usage requirements.
• Confirm that the plate thickness, number of layers, and keel spacing match.
• Check whether the accessories are of the same system and whether the galvanized layer meets the standards.
• Confirm that layout, inspection openings and electromechanical points are coordinated.

The core of selection is matching. Only when the system, panels, keels and accessories form a complete combination can the performance be stably reproduced.
