A rock wool board, also known as mineral wool board or stone wool board, is a type of insulation material used in construction for thermal and acoustic insulation purposes. It is made from basalt rock, which is heated to a high temperature and then spun into fibers. These fibers are bound together to form rigid or semi-rigid boards.

Here are some key features and applications of rock wool boards:

1. Thermal Insulation: Rock wool boards have excellent thermal insulating properties, which means they can effectively reduce heat transfer. They are used in walls, roofs, and floors to improve energy efficiency by minimizing heat loss or gain.

2. Acoustic Insulation: In addition to thermal insulation, rock wool boards also provide soundproofing benefits by absorbing and dampening sound waves. This makes them suitable for applications where noise control is essential, such as in commercial buildings or residential spaces.

3. Fire Resistance: Rock wool is inherently fire-resistant, and rock wool boards inherit this property. They are often used in buildings to enhance fire safety by providing a barrier against the spread of flames and heat.

4. Durability: Rock wool boards are durable and resistant to moisture, making them less prone to rot or degradation over time. This durability contributes to their long lifespan.

5. Environmentally Friendly: Many rock wool products are considered environmentally friendly because they are made from natural materials and can be recycled. They do not contain harmful substances.

6. Easy Installation: Rock wool boards are typically available in various sizes and thicknesses, making them easy to install in different construction applications.

7. Applications: Rock wool boards are used in a variety of applications, including residential and commercial construction, industrial facilities, HVAC systems, and more.

Overall, rock wool boards are versatile insulation materials that offer excellent thermal and acoustic performance, fire resistance, and durability. They are commonly used in building envelopes to improve energy efficiency and create a comfortable and safe indoor environment.
