Exterior Wall Sandwich Panel: Overseas Project FAQ
For overseas projects such as factories, warehouses, cold storages and prefabricated buildings, many purchasers have various doubts about exterior wall sandwich panel. Below are practical answers prepared for global contractors and importers.
Q: What core factors should be considered when selecting exterior wall sandwich panel for tropical‑humid overseas projects?A: Prioritize weather resistance, fire rating and core‑material stability. Pay attention to anti‑corrosion surface treatment and waterproof joint structure to adapt to high‑temperature and heavy‑rainfall environments. SAMZOON provides targeted exterior wall sandwich panel solutions and supports free samples for performance reference.
Q: What is the difference between exterior wall sandwich panel and interior partition sandwich panel? Can interior panels replace exterior wall sandwich panel for building facades?A: Exterior wall sandwich panel adopts reinforced metal skins and anti‑aging sealing structure to resist outdoor UV rays, rain and wind loads. Ordinary interior partition sandwich panel lacks UV‑resistance and anti‑corrosion performance. It cannot replace exterior wall sandwich panel for outer facades; otherwise, premature aging and water leakage will occur.
Q: Which core material performs better for exterior wall sandwich panel: PU, rock wool or EPS?A: PU exterior wall sandwich panel delivers excellent thermal insulation. Rock‑wool exterior wall sandwich panel reaches Class‑A fire‑proof grade. EPS exterior wall sandwich panel has obvious cost advantages. Please confirm local building fire codes and insulation requirements before finalizing your choice. SAMZOON offers customized exterior wall sandwich panel with PU, rock wool, EPS and magnesium‑oxide core options.
Q: What common problems will appear during exterior wall sandwich panel installation for overseas projects?A: Joint water leakage, fastener corrosion and improper gap handling are common risks. High‑quality weather‑resistant sealant and matching accessories must be used. SAMZOON provides complete on‑site construction and joint‑sealing technical guidance for exterior wall sandwich panel.
Q: Can exterior wall sandwich panel be applied to cold‑storage and clean‑room outer facades in overseas markets?A: Yes. Select exterior wall sandwich panel with suitable fire rating and thermal‑insulation performance according to project requirements. Stainless‑steel‑faced exterior wall sandwich panel is available for sites with corrosive vapor or frequent high‑pressure washing.
Q: Does exterior wall sandwich panel require special maintenance after long‑term outdoor use?A: Regularly check sealant aging status and surface corrosion of exterior wall sandwich panel. Re‑seal cracked or peeling sealant in time. Avoid strong corrosive cleaning agents, so exterior wall sandwich panel can maintain stable facade performance for a long time.
