❓PU Sandwich Panels: Factory & Warehouse FAQ
2026-08-21
Q1: 🏭 What non‑purification projects are PU sandwich panels suitable for?
A1: PU sandwich panels feature constant‑temperature insulation, light weight and fast installation. They are mainly used for steel‑structure industrial factories and constant‑temperature warehouses, for workshop exterior walls, partition walls and general warehouse thermal enclosures, not limited to cold storage or clean‑room projects. SAMZOON can customize proper specifications of PU sandwich panels according to factory and warehouse operating conditions.
Q2: ⚙️ What advantages do PU sandwich panels bring to industrial factories compared with traditional boards?
A2: With high closed‑cell ratio and low thermal conductivity, PU sandwich panels deliver outstanding thermal insulation performance and cut energy consumption for factory air‑conditioning and ventilation. Light‑weight and flat‑surfaced PU sandwich panels fit prefabricated steel‑structure construction. As a Foshan‑based original manufacturer, SAMZOON offers professional selection guidance for factory projects.
Q3: 🧯 Do constant‑temperature warehouses need flame‑retardant PU sandwich panels?
A3: Yes. Warehouses store concentrated goods with strict fire‑safety requirements. B1 flame‑retardant PU sandwich panels are widely adopted in engineering; they self‑extinguish and stop flame spread to satisfy most industrial warehouse fire‑acceptance standards and reduce fire risks.
Q4: 🏠 Can PU sandwich panels be used for factory roofs? What construction notes should be followed?
A4: PU sandwich panels work well for factory roof enclosures with integrated waterproof and thermal‑insulation functions. Contractors shall handle panel lap sealing and roof edge finishing carefully to prevent rainwater from invading PU sandwich panel core and causing insulation failure or moisture deformation. SAMZOON supplies complete construction technical guidance.
Q5: ⚠️ What typical pitfalls occur when purchasing PU sandwich panels for factory and warehouse projects?
A5: Many projects mistakenly adopt B2 combustible PU sandwich panels or low‑density foamed boards, which later result in poor thermal performance, core collapse, delamination and water leakage and block project acceptance. SAMZOON supports free samples for pre‑verification to avoid hidden engineering risks.
Q6: 💧 Are PU sandwich panels durable for factories in rainy and humid South China?
A6: PU sandwich panels fit local conditions well. Their closed‑cell structure brings low water‑absorption and anti‑mildew properties. Thermal performance will not degrade under long‑term high‑humidity, suitable for factory exterior walls and open‑air warehouse enclosures. SAMZOON owns abundant completed industrial cases across South China.
Q7: 🔧 Can old steel‑structure factories be retrofitted directly with PU sandwich panels?
A7: Yes. PU sandwich panels support renovation of new and existing steel‑structure factories. Prefabricated installation saves construction time and improves thermal insulation and noise‑reduction performance. For tight‑schedule orders, SAMZOON arranges priority production of PU sandwich panels to keep projects on track.
Q8: 📋 What key acceptance items shall be checked after installing PU sandwich panels in workshops and warehouses?
A8: Inspect surface flatness, joint sealing status, no delamination or hollow areas, and zero leakage on walls and roofs. Confirm flame‑retardant grade and thickness of PU sandwich panels comply with industrial acceptance codes. SAMZOON assists clients with acceptance coordination and rectification suggestions.
Q9: 🛡️ Can PU sandwich panels be custom‑made with stainless‑steel facings for special‑condition factories?
A9: Custom stainless‑steel faced PU sandwich panels are available. They resist mild corrosion and dust and are easy to clean, performing better than ordinary color‑steel PU sandwich panels for high‑dust or slightly corrosive factories and warehouses. SAMZOON undertakes non‑standard composite panel customization.
Q10: 📏 What thickness of PU sandwich panels is recommended for factories and warehouses?
A10: 50mm‑75mm PU sandwich panels satisfy general thermal demands for factory walls. 75mm‑100mm thicker PU sandwich panels are preferred for roofs and constant‑temperature warehouses for better heat preservation and wind‑resistance. Specs can be fine‑tuned according to real‑site working conditions.
