ISOKING 50mm Mineral Wool Board for Curtain Wall is engineered for high-rise glass, aluminum, and composite curtain wall systems. Made from high-grade natural basalt stone, this 50mm stone wool panel provides superior thermal insulation, perimeter fire containment (firestopping), and acoustic damping. Featuring high dimensional stability and moisture resistance, it effectively prevents thermal bridging and smoke propagation while maintaining structural integrity in demanding architectural facades.
Length: 1.2m
Width: 0.6m
Thickness: 50mm
Density: 32kg/m³-180kg/m³
Modern high-rise facades require insulation materials capable of resisting intense thermal cycles, high wind loads, and potential fire propagation. Our 50mm mineral wool board is purpose-built to meet the stringent demands of glass, aluminum, and ventilated curtain wall assemblies. Crafted from premium basalt rock fibers, this medium-thickness stone wool slab provides continuous thermal insulation while serving as a vital barrier against floor-to-floor flame spread.
Key Architectural Applications: Engineered for spandrel glass backings, perimeter fire barrier joints (firestopping), rainscreen cladding systems, and architectural composite metal panels. It effectively prevents condensation buildup, reduces outdoor street noise intrusion, and preserves energy integrity across the entire building envelope.

We partner directly with curtain wall fabricators, facade engineering consultants, and commercial building material importers to streamline site installation and lower total procurement risks:
Q1: How does 50mm mineral wool perform in perimeter fire barrier systems for curtain walls?
When installed with approved mechanical fasteners and smoke sealants, our 50mm stone wool boards comply with ASTM E2307 perimeter fire containment standards, blocking flame passage between floor slabs and curtain wall spandrels.
Q2: Can this product be supplied with aluminum foil or fiber facings?
Yes, we offer factory-laminated reinforced aluminum foil (FSK) or black glass tissue facings to enhance vapor barrier properties and anti-glare aesthetics inside glass curtain walls.
Q3: Do you provide ASTM test reports and Material Test Certificates (MTC)?
Absolutely. Every shipment is accompanied by comprehensive quality control documentation and ASTM third-party test reports for project submittals.
Q4: What is the typical lead time for custom container loads of curtain wall wool boards?
Our daily capacity guarantees standard production completion within 7 to 10 days for full container orders (FCL), ensuring reliable delivery schedules for major construction deadlines.
