FANRYN Rock Wool Blanket with Black Tissue
Versatile thermal and acoustic insulation solution for modern construction applications, featuring black tissue facing for enhanced protection and aesthetics.
Product Overview
FANRYN Rock Wool Blanket is a high-performance insulation material manufactured from natural basalt and limestone. The raw materials are melted at over 1450°C in a cupola, then fiberized into fine, inorganic fibers. These fibers are bonded with a thermosetting resin and cut into flexible blankets for easy handling and installation.
Available with black tissue facing, this product combines superior insulation performance with enhanced surface protection and aesthetic appeal—ideal for exposed or semi-exposed applications.

Product Benefits
Superior Fire Safety
Non-combustible and classified as Class A1 fire rating. With a melting point above 1000°C, it provides critical fire protection in walls, roofs, and industrial applications.
Excellent Thermal Insulation
Low thermal conductivity (≤0.044 W/mK) ensures energy efficiency—reducing heating and cooling costs in both residential and commercial buildings.
Effective Acoustic Control
The dense fiber structure absorbs sound and reduces noise transmission, making it ideal for partition walls, floating floors, and mechanical rooms.
Moisture & Condensation Resistance
Moisture content ≤0.5%, and the material resists water absorption, helping to prevent mold growth and structural damage in humid environments.
Eco-Friendly & Non-Corrosive
Made from natural stone, free from harmful chemicals, and safe for use with metal structures—no corrosion risk to pipes or steel frames.
Easy to Cut & Install
The flexible blanket form allows for quick on-site cutting and fitting, reducing labor time and material waste.
Common Applications
- External wall insulation systems
- Roofing and ceiling insulation
- Floating floors and partition walls
- Large-diameter pipeline insulation
- Industrial plants and equipment
Packaging Options
We offer flexible packaging to suit different shipping and storage needs:
- Plastic bag + woven bag (standard export packing)
- Plastic bag + PE shrinking bag
- PE shrinking bag only
