The Basalt Rock Wool Board is a premium, non-combustible insulation material engineered for exceptional fire safety and energy efficiency. Manufactured from natural basalt ore through high-temperature melting and fibrillating, it offers unparalleled thermal and acoustic insulation for demanding applications in construction, marine, and industrial sectors.

Features

A60 Fire Resistance‌: Achieves the highest fire safety rating (A60), effectively preventing flame spread and protecting structural integrity.

‌Superior Thermal Insulation‌: Low thermal conductivity significantly reduces heat transfer, maintaining indoor temperature stability and cutting HVAC energy costs.

‌Excellent Acoustic Insulation‌: Dense fibrous structure effectively absorbs sound, reducing noise pollution and enhancing comfort.

‌Long-Term Durability‌: Chemically inert and resistant to moisture, corrosion, and aging, ensuring stable performance in harsh environments.

‌Eco-Friendly & Water-Repellent‌: Made from natural minerals, with optional water-repellent treatment for use in humid conditions.

Application

‌Building & Construction‌: External wall insulation (ETICS), roof insulation, partition walls, and fire barriers in commercial and residential buildings.

‌Marine & Shipbuilding‌: Insulation for engine rooms, accommodation cabins, and cargo holds to meet stringent fire safety (SOLAS) and thermal requirements.

‌Industrial Applications‌: Insulation for pipelines, boilers, storage tanks, and HVAC systems in power plants, refineries, and factories.

Production Process

Basalt rock wool board production process mainly includes raw material ingredients, high-temperature melting, fiber processing, curing and processing steps. The specific process is as follows:

1. raw material ingredients: basalt, slag, dolomite, coke and other raw materials into the high melting furnace according to a certain ratio, after sufficient melting, the formation of a uniform melt.

2. High-temperature melting: The melt is fed into the high-temperature melting equipment to further homogenize the melt through high temperature action and remove the impurities and gases.

3. Fiberization: the high-temperature melting of the melt through the centrifuge or air blowing and other equipment, so that it quickly cooled fibrosis, the formation of rock wool fibers.

4. curing process: the fibrillated rock wool fibers and the appropriate amount of binder, dust-proofing agent, water-repellent agent and other additives mixed, through the pressing, curing and other processes, the formation of a certain strength and thermal insulation properties of basalt rock wool board.
