High Quality Chinese Rock Wool Blanket With Black Fiberglass Tissue Supplier Residential Thermal Insulation Soundproofing Rock Wool Blanket

This composite material combines the inherent strengths of rock wool with the engineered benefits of a black fiberglass tissue surface layer, delivering a robust solution for demanding insulation applications. It integrates fire resistance, thermal insulation, acoustic absorption, and enhanced durability.

Excellent Thermal Insulation and Fire Resistance
The dense mineral fiber matrix provides exceptional thermal insulation, significantly reducing heat transfer and lowering energy consumption. As a naturally non‑combustible material (Class A1), the rock wool core releases no toxic fumes in case of fire, ensuring the highest level of fire safety—a performance fully maintained by the fiberglass tissue facing.

Durable Performance, Enhanced Handling, and Comfort
The laminated black fiberglass tissue provides a critical upgrade: it reinforces the surface, preventing fiber dispersal and significantly improving tear and abrasion resistance. This makes the product exceptionally durable during handling, installation, and service. Underneath this protective layer, the hydrophobic rock wool fiber structure resists moisture and inhibits mold growth, ensuring long‑term stability and effective sound absorption for quieter, more comfortable spaces.

Reliable Structural Integrity with Reinforced Surface
Unlike standard meshes, the integrated black fiberglass tissue acts as a continuous, high‑strength reinforcing layer. It securely encapsulates the wool, preventing delamination and providing essential structural support to the entire insulation system. This built‑in reinforcement ensures dependable, long‑term performance in applications such as pipe wrapping, duct insulation, and curved surface coverage.
