Packing & Delivery

Packing & Delivery: Fire-Resistant Black Rock Wool BoardMade from high-quality natural basalt fiber, our fire-resistant black rock wool board delivers exceptional performance in fire safety, thermal insulation, and sound absorption. With Class A1 non-combustible rating, it does not burn or release toxic smoke under high temperatures, effectively slowing fire spread and significantly improving building safety. The board can withstand continuous working temperatures of 600–800°C, ensuring reliable performance in high-temperature environments.
To ensure the product reaches you in perfect condition, we use waterproof plastic film wrapping combined with heat-treated wooden pallets for standard export packaging. Each pallet is secured with straps to prevent shifting and damage during long-distance transportation, while the compact stacking design maximizes container loading efficiency.
This versatile board is widely used in building fire sealing, exterior wall insulation, curtain wall systems, HVAC ductwork, and industrial equipment insulation. With stable quality and secure packaging, we guarantee safe delivery to meet your project needs.Black Rock Wool Board with Optional Aluminum Foil Facing

Our black rock wool board is available with or without reinforced aluminum foil facing, designed to meet diverse industrial and construction insulation needs. Made from high-quality basalt fiber, the board features a stable density range of 80–180kg/m³ and a standard size of 1200×600mm, with customizable thicknesses from 30–100mm to suit specific project requirements.
The optional aluminum foil facing provides multiple functional benefits:
Enhanced Water & Vapor Resistance: The foil layer acts as an effective moisture barrier, preventing condensation and water vapor penetration, ensuring long-term insulation performance even in humid or high-moisture environments.
Improved Thermal Efficiency: The reflective aluminum surface reduces radiant heat transfer, boosting the overall thermal insulation efficiency of the board.
Corrosion Protection: It shields the rock wool core from corrosive substances and chemical damage, extending the service life of the insulation system.
Easier Installation: The smooth foil surface simplifies cutting and installation, while also providing a cleaner, more finished appearance for exposed applications.
This versatile board is ideal for a wide range of applications, including industrial pipes, HVAC ductwork, exterior wall insulation, roof systems, and equipment enclosures. Whether you need basic thermal insulation or enhanced moisture and corrosion protection, our black rock wool board with optional foil facing delivers reliable, long-lasting performance for your projects.
