PIR Sandwich Panel: Industrial Project FAQ
PIR sandwich panel is widely used for cold‑storage enclosure, clean‑room partition, temperature‑controlled workshop and industrial building insulation. Global purchasers and contractors often have practical concerns about PIR sandwich panel before placing orders. Below are targeted answers for overseas project reference.
? Q: What core indicators should I check when selecting PIR sandwich panel for cold‑storage projects?A: Focus on thermal conductivity, fire rating, panel thickness and water absorption rate of PIR sandwich panel. Low‑lambda PIR sandwich panel delivers stable insulation performance for long‑term cold‑storage operation. SAMZOON supplies qualified PIR sandwich panel and supports free samples for performance testing.
? Q: What is the main difference between PIR sandwich panel and ordinary PU sandwich panel?A: PIR sandwich panel owns better fire‑resistance and lower smoke density compared with common PU sandwich panel. PIR sandwich panel keeps excellent thermal‑insulation property, which makes PIR sandwich panel more suitable for projects with strict fire‑safety requirements.
? Q: Can PIR sandwich panel be adopted in clean‑room and pharmaceutical workshop projects?A: Yes. Choose smooth‑surface PIR sandwich panel with good surface flatness. Strictly handle seam sealing for PIR sandwich panel to reduce dust accumulation. Standard PIR sandwich panel needs proper surface treatment for high‑grade clean‑room zones.
? Q: What installation notes should be followed for PIR sandwich panel?A: Avoid heavy impact to prevent skin delamination of PIR sandwich panel. Minimize on‑site cutting. If cutting is necessary, seal cut edges well to prevent moisture penetration into PIR sandwich panel core. SAMZOON provides practical construction guidance for PIR sandwich panel.
? Q: What is the service life of PIR sandwich panel under normal working conditions?A: High‑quality PIR sandwich panel can maintain stable performance for many years with correct installation and good sealing. Service life of PIR sandwich panel will decrease obviously under long‑term high‑humidity and corrosive‑gas environment.
? Q: What fire‑rating can PIR sandwich panel achieve?A: PIR sandwich panel can reach B1‑class fire‑retardant standard. Compared with EPS and ordinary PU materials, PIR sandwich panel shows lower heat release and less smoke output during burning.
? Q: Is PIR sandwich panel suitable for high‑humidity workshop environment?A: PIR sandwich panel has low water‑absorption rate. For continuous high‑humidity scenarios, well‑sealed PIR sandwich panel with anti‑corrosion metal skins is recommended to avoid core dampness.
? Q: What thickness of PIR sandwich panel is commonly used for cold‑storage walls?A: 80‑150 mm PIR sandwich panel is widely used for cold‑storage walls. Exact thickness of PIR sandwich panel depends on target storage temperature and local climate. SAMZOON can give targeted thickness suggestions for your PIR sandwich panel.
