| Cleanroom Disadvantages |
Low Fire Rating (B1), toxic fumes when burning, structure unstable at high temps. |
Low Fire Rating (B1), average strength/weather resistance. |
Fire Rating is B1, not Class A. Higher cost than PU/Silica Rock. |
Very High Cost, Relatively Heavy Weight. |

| Recommended Installation Location |
Workshop Partition Walls/Roofs (No Fire Requirement) |
Workshop Partition Walls (No Fire Requirement) |
Partition Walls (Some Fire Requirement, Not Class A) |
Partition Walls, Doors/Windows, Column Cladding, Equipment Enclosures |
| Location Selection Rationale |
Not recommended for core cleanroom partitions/ceilings due to fire rating. Mainly for external workshops, cold storage, etc. |
Prohibited in core cleanroom areas due to fire rating. Only for ordinary workshops, warehouses. |
Better fire performance among B1 grade, can be used in clean areas with lower fire requirements, but not the mainstream choice. |
Excellent corrosion resistance and cleanability. Often used for walls in Food/Pharma industries, high-moisture areas, or as functional panels. |
| Recommended Application Projects |
Warehouses, External Packaging Areas, Non-core areas requiring extreme insulation. |
Cost-sensitive general industrial plants, warehouses. |
Light industrial, storage clean areas where B1 fire rating is acceptable. |
Environments with high corrosion, frequent cleaning, sterile requirements: Food Processing, Pharma Production, Labs, Hospital ORs. |
