💡 Detailed Recommendations
-
🏗️ Prefabricated building, hospital, cleanroom: Directly consider prefabricated composite panels with system-level verification and pre-engineered connection details. SAMZOON provides free samples for physical quality verification.
-
🏭 General enclosure (warehouse, workshop): Traditional sandwich panels offer lower initial cost — suitable for applications where system-level verification is not required.
-
🔥 Fire-rated application (Class A required): Prefabricated composite panels with rock wool or magnesium cores offer system-level Class A verification — suitable for fire-rated applications.
-
💨 Airtightness-critical application (cleanroom, hospital): Prefabricated composite panels with factory-controlled connection details ensure system-level airtightness.
-
💰 Budget-sensitive general enclosure: Traditional sandwich panels can suffice for general enclosure where system-level verification is not required.
🎯 Key Takeaways
-
🏗️ Prefabricated composite panels offer system integration, pre-engineering, system-level verification, and lower total project cost; traditional sandwich panels offer lower initial cost and are widely available.
-
🔥 Fire performance: both achieve Class A/B1, but prefabricated composite panels offer system-level fire verification — critical for hospitals and cleanrooms.
-
💨 Airtightness: prefabricated composite panels offer factory-controlled airtightness; traditional sandwich panels depend on on-site work.
-
💰 Cost: prefabricated composite panels have a higher initial unit price but lower total project cost; traditional sandwich panels are cheaper initially but require more on-site labor.
-
🎯 Scenario-based selection matters more than price comparison: prefabricated composite panels for prefabricated buildings, hospitals, and cleanrooms; traditional sandwich panels for general enclosure.
-
🏭 SAMZOON provides both prefabricated composite and traditional sandwich panels, with selection guidance based on application requirements for South China projects.
