What are the advantages and characteristics of 120K rock wool blanket insulation material for tunnels? The term '120K' here usually refers to high-density rock wool board/felt with a density of 120kg/m ³. In tunnel engineering, this high-density rock wool material is the core component of fire prevention and insulation systems. In actual tunnel engineering, 120K rock wool blanket is often used as the core filling material for tunnel fireproof board (i.e. "rock wool sandwich fireproof board"), or directly as a spray/adhesive insulation fireproof layer.
                                                                
120K high-density tunnel specific rock wool blanket: A-level fireproof, thermal insulation, sound absorption and noise reduction, moisture and vibration resistance, designed for long-term safe and stable operation of tunnels.
Functional advantages of rock wool blanket:
1. Excellent fire safety (core advantage)
2. Excellent mechanical strength and compressive performance
3. Efficient thermal performance
4. Excellent sound absorption and noise reduction function
5. Hydrophobicity and Durability


What are the advantages and characteristics of 120K rock wool blanket insulation material for tunnels? In the special environment of semi enclosed, high wind speed, and extremely high fire safety requirements such as tunnels, the high-density characteristics of 120K make its performance far superior to ordinary building insulation rock wool. In response to the strict requirements for insulation and fireproof materials in tunnel engineering, 120K high-density rock wool blanket (density 120kg/m ³) has become the industry's preferred choice due to its excellent physical properties. Rosewool Insulation Refractory Co.,Ltd., with its professional technology, excellent quality, and attentive service in the field of 120K high-density rock cotton blankets, is fully capable of becoming your trusted partner.
