Rock Wool Board for Fire Barrier
Product Overview
The rock wool board for fire barrier is a professional fireproof and thermal insulation material specially developed for the needs of building fire protection, thermal insulation and sound absorption. It is made of natural basalt as the main raw material, which is melted at high temperature (above 1500℃) and then drawn into fibers, mixed with environmentally friendly inorganic binders, and pressed into a solid board through high-temperature curing. Its core advantage lies in that while ensuring excellent thermal insulation and sound absorption performance, it has extremely high fire resistance, which can effectively block the spread of fire and reduce energy consumption, and is widely used in various building and industrial scenarios.
Different from ordinary rock wool boards, this rock wool board for fire barrier has higher density, better compression resistance and wear resistance, and does not shed fibers, which is more suitable for long-term use in various harsh environments. It is non-toxic, tasteless, non-corrosive, and does not release harmful substances, fully complying with international environmental protection standards and fire safety regulations. It is an indispensable core material for modern building fire protection and energy saving.

Key Features
- Fireproof Performance: It reaches Class A non-combustible standard, which is consistent with the national fire protection requirements. It can effectively resist high temperature, prevent fire spread, and ensure the safety of buildings and personnel. Even in the case of fire, it will not burn, melt or release toxic gases, and can effectively block the spread of fire, providing a safe protection barrier for the building.
- Thermal Insulation Performance: The thermal conductivity is low, which can effectively block the transfer of heat, reduce the loss of indoor and outdoor heat, help the building achieve energy saving goals, reduce the operation cost of air conditioning and heating, and improve the comfort of the living and working environment.
- Sound Absorption Performance: The porous structure of the board can effectively absorb noise, reduce the interference of external noise, and is suitable for public places, office buildings, workshops and other scenarios that require quiet environment.
- Durability & Environmental Protection: The board is firm and durable, not easy to deform, crack or fade, and has good weather resistance, which can adapt to different climate environments (high temperature, humidity, cold, etc.). It is made of environmentally friendly raw materials, non-toxic and tasteless, in line with international environmental protection standards, and does not cause pollution to the environment and human body.
- Easy Construction: The board is light in weight, easy to cut, drill and install. It can be flexibly cut according to the actual construction needs, and can be closely combined with various building materials (such as concrete, steel structure, curtain wall, etc.), which greatly improves the construction efficiency and reduces the construction cost.
