FAQ Sniper (Pure Industrial, No Cleanroom, Only English)
Q: 🏭 What wall sandwich panel core material fits factory exterior wall and warehouse partition?
A: Core material selection for wall sandwich panel depends on local fire code, climate and budget. EPS suits temporary buildings; rock wool for high‑fire‑risk sites; PU delivers best thermal insulation; silicon‑rock balances fire‑proof and weather performance. SAMZOON gives material suggestions for your industrial project.
Q: 📐 What standard sizes are available for industrial wall sandwich panel?
A: Common effective widths of wall sandwich panel are 950 mm, 1000 mm and 1150 mm. Thickness options: 50 mm,75 mm,100 mm,120 mm,150 mm. Length can be cut‑to‑size, you need to match container dimension for sea‑export orders.
Q: 💧 Why does wall sandwich panel wall leak after installation?
A: Water leakage of wall sandwich panel mostly comes from poor joint sealing, insufficient lap width, damaged end‑face or improper fastener tightening. Outer‑only sealant cannot resist long‑term temperature expansion and contraction, multi‑layer sealing is required for exterior wall projects.
Q: 🔥 Which wall sandwich panel meets A‑class fire‑proof requirement for industrial buildings?
A: Rock wool wall sandwich panel and silicon‑rock wall sandwich panel reach Class‑A non‑combustible grade. EPS is B2 grade while PU wall sandwich panel is B1 self‑extinguishing. Always confirm local fire‑safety standard before ordering wall sandwich panel.
Q: 🌦️ Can wall sandwich panel work in heavy‑rain and high‑humidity coastal regions?
A: Wall sandwich panel can be applied in humid coastal zones, but you need closed‑cell core material, high weather‑resistant coating and strict end‑face sealing. Ordinary rock‑wool wall sandwich panel without edge sealing will absorb moisture and degrade performance quickly.
Q: ⚙️ What accessories do I need together with wall sandwich panel?
A: Wall sandwich panel supporting parts include purlins, self‑drilling screws with EPDM washers, flashing trims, waterproof gaskets and outdoor‑grade sealant. Mismatched accessories are a hidden cause of wall failure for industrial projects.
Q: 🚢 What should I pay attention to for exporting wall sandwich panel by sea?
A: Wall sandwich panel for sea shipment needs IPPC‑marked pallets, full stretch‑film wrapping and end‑face protection. Place desiccant inside container to avoid condensation‑caused rust and core‑material damp during long ocean transit.
Q: 💰 How to compare quotes for wall sandwich panel from different suppliers?
A: When comparing wall sandwich panel quotations, do not only check unit price. Verify steel sheet thickness, core density, coating grade, fire‑test report, cutting tolerance and included accessories, many low‑bidding items cut these key parameters.
Q: 🛠️ Can wall sandwich panel be used for both exterior wall and inner partition?
A: Yes, wall sandwich panel serves for both exterior enclosure and inner partition. Exterior wall wall sandwich panel needs UV‑resistant coating and complete waterproof system; inner partition wall sandwich panel can adopt relatively economical configuration.
Q: ⚠️ What common mistakes should buyers avoid for wall sandwich panel projects?
A: Typical mistakes: ignore local fire‑code requirements, use indoor sealant for exterior joints, insufficient lap overlap, over‑tighten screws denting wall sandwich panel surface, skip end‑sealing for cut panel ends. SAMZOON provides remote technical support to avoid these risks.
