Rock Wool (also known as Stone Wool) is a mineral-based insulation made from volcanic basalt rock melted and spun into fibers. It offers exceptional fire resistance, thermal stability, and sound insulation for demanding environments.
At NNRV, we provide multigrade, project-specific Rock Wool products, from non-combustible façade insulation boards to high-temperature pipe wraps and fire-resistant acoustic panels — always compliant with global building codes and energy standards.

❓ Frequently Asked Questions (FAQs)
Q1: What’s the difference between rock wool and glass wool?
Rock wool withstands higher temperatures and offers better acoustic and fire resistance.
Q2: Can I use rock wool in fire-rated wall assemblies?
Yes — it is A1 rated and widely used for fire-stop and fire-resistive barriers.
Q3: Are foil-faced or mesh-faced options available?
Yes — with reinforced aluminum foil, kraft paper, or wire mesh facing.
Q4: Is rock wool water-resistant?
Yes — it is hydrophobic and resists mold and moisture absorption.
Q5: What’s the MOQ?
Generally 1×20 ft container (approx. 350–500 m² depending on density and type).
