Premium Rock Wool Board
I. Product Introduction
Rock wool board is manufactured using natural basalt, diabase, and other minerals as the main raw materials. After being melted at temperatures above 1450°C, the material is processed into inorganic fibers using internationally advanced centrifugal technology and further processed through pendulum layering and curing.
It is widely used in building exterior wall insulation, thermal insulation of industrial equipment and pipelines, and fire protection in ship cabins. It is an ideal material for energy efficiency, environmental protection, and safety protection.
II. Features
A1 Fire Rating – Achieves the highest fire protection classification. It is non-combustible and effectively slows the spread of fire.
Efficient Thermal Insulation – Thermal conductivity as low as 0.035–0.044 W/(m·K), providing excellent insulation performance.
Sound Absorption and Noise Reduction – The porous fiber structure effectively absorbs sound waves and significantly reduces environmental noise.
Water Repellent and Moisture Resistant – Water repellency ≥99%, ensuring long-term stable insulation performance.
Environmentally Friendly and Durable – Made from inorganic materials, resistant to mold and corrosion, with a long service life.
III. Applications
Building Exterior Wall Insulation – Used in various external thermal insulation systems to meet energy-saving design standards.
Industrial Equipment Insulation – Thermal protection for pipelines, storage tanks, boilers, and other industrial equipment.
Fire Barriers – Fire sealing for building fire compartments and cable wall penetrations.
Shipbuilding – Thermal insulation and fire protection for ship cabins to meet marine safety standards.
HVAC Systems – Insulation for air ducts and soundproofing treatment for equipment rooms.

FAQ
Q1: Does rock wool board absorb water? How is its moisture resistance?
A1: With a water repellency rate of ≥99%, it has excellent moisture resistance and is not easily affected by humidity during long-term use.
Q2: What should be considered during rock wool board installation?
A2: Ensure the base surface is flat and dry; use specialized adhesives for installation; properly seal all joints; and maintain proper ventilation and safety protection during installation.
Q3: How can the quality of rock wool boards be identified?
A3:
First, check the density uniformity;
Second, test thermal conductivity and water repellency;
Third, review product test reports (fire resistance and environmental certifications);
Fourth, observe whether the fibers are fine and free of impurities.
