Vermiculite Fire Boards | High-Temp Insulation & Cost Savings

Vermiculite fire board is a premium inorganic fireproof and thermal insulation material manufactured from non‑asbestos expanded silver vermiculite and specialized inorganic fillers, processed through high‑pressure compression and high‑temperature sintering to form a uniform, controllable pore structure. This advanced production method endows the board with exceptional fire resistance, low thermal conductivity, stable chemical properties, light weight, and high mechanical strength, making it a core component in passive fire protection and high‑temperature insulation systems across construction and industrial sectors. In building fire protection, vermiculite fire board is extensively used for steel structure cladding, fire compartment walls, elevator shafts, and ventilation duct enclosures. It effectively isolates flames and high‑temperature heat flux, delays temperature rise in load‑bearing steel components, preserves structural stability during fire events, and complies with stringent fire‑rating codes for high‑rise buildings, industrial facilities, hospitals, schools, and public venues. For stove, fireplace insert, and enclosure applications, vermiculite fire board provides reliable high‑temperature insulation, enhances combustion efficiency, reduces exterior surface temperature, and resolves long‑standing durability challenges faced by equipment manufacturers. In the metallurgical industry, vermiculite fire board serves as a key insulation layer for steel ladles and tundishes, forming a stable thermal barrier that minimizes molten steel temperature loss and improves casting quality and process stability.
