What is Rockwool panel?
Rockwool Panel or also known as flat mineral wool is a product commonly used for exterior wall construction. This product has extremely good fire resistance up to 8 hours and is durable over time.
Mineral wool can be used in projects requiring high fire protection standards such as industrial electric furnaces, heat insulation of factory roofs or industrial zones,...
In addition, this product is also widely used in civil works such as bars, dance clubs and karaoke bars,...
Structure of Rockwool fireproof panel wall
Rockwool fireproof panel wall consists of 3 layers: 2 surface layers made of galvanized steel with the middle layer being mineral wool insulation material (Rockwool). These metal panels can also be aluminum rolled into corrugated or patterned according to customer requirements.
Mineral wool has good fire resistance because this product is made from basalt and dolomite ore melted at a temperature of 1600 degrees Celsius. After being heated, it becomes small fibers mixed with some specialized chemicals.
Therefore, this product has the physical properties and chemical composition of basalt, which is easily decomposed in nature after disposal and is especially fireproof.
Advantages and disadvantages of fireproof Rockwool panels
- Advantages of Rockwool panels
- Good fire resistance: The first advantage to mention when mentioning Rockwool is its extremely high fire resistance. As mentioned, this product is made from fireproof materials, so it has the ability to prevent the development of fire, so it is very suitable for fireproof constructions or areas where fires are common.
- High insulation: Rockwool has super good insulation performance thanks to the tiny air layers between the uniform and extremely small mineral wool fibers with the product's lambda being only 0.044 (W/mK).
- Super durable: Another advantage of inorganic mineral tape is that even if used for a long time, it will not change its condition and will not corrode. Mineral wool fibers are quite hard and have high resilience, leading to extremely durable products even when subjected to shock, compression or vibration.
- Good noise reduction: In addition to the above advantages, this product also has good noise reduction ability. That is why it is often used in karaoke bars and dance clubs.
- Limitations
However, in addition to the outstanding advantages mentioned above, fireproof rockwool panels also have limitations that can be mentioned as:
- Cotton fibers are quite hard and thin, so they can easily puncture the skin when in direct contact, causing itching and skin irritation.
=> Therefore, when constructing mineral wool, you need to equip additional protective clothing and equipment.
Applications of fireproof Rockwool panels
Rockwool mineral wool panels are effective cladding and insulation products for industrial factories. In addition, they are also used to build curtain walls or room dividers, or used as a lightweight facade panel.
Besides, the product is also applied in other projects such as:
- Making panel walls for steel factories, furnaces, kilns, food processing plants.
- Making clean room panel walls in pharmaceutical and electronic equipment production.
- Making cold storage panel walls , ceiling panels in supermarket systems.
- Assemble offices, temporary houses, motels.
- Administrative offices, gymnasiums, boarding houses, residential houses,...
Notes when constructing Rockwool panel partitions
To be able to construct fireproof rockwool panel walls effectively, you need to note a few things below.
- Choose the right insulation
You should carefully choose the right type of mineral wool in terms of color, size, thickness, structure and purpose of the product to bring the highest aesthetics and durability.
- Arrange the panels in a straight line
Not aligning the panels properly is the cause of unstable structure, gaps and reduced durability. Therefore, you need to align the panels properly.
In addition, you also need to calculate the thermal expansion and contraction factors of the product to avoid shrinkage after long-term use or when exposed to high temperatures.
- Do not come into direct contact with the Rockwool panel.
During the construction process, you should not come into direct contact with mineral wool. When installing this product, you must wear specialized gloves, protective clothing as well as use a full mask and dust mask.
Besides, you also need to use a vacuum cleaner to clean the work area after construction because the broom cannot clean the mineral wool crumbs.
- Arrange the construction area neatly
You should arrange the construction area neatly to ensure that the construction and installation go smoothly. Moreover, in the mineral wool construction area, you should open the ventilation doors to optimize the working space.
- Follow the installation instructions
To ensure the effectiveness of the product, you also need to install it according to the manufacturer's instructions. The most typical is to prevent air, water as well as effective insulation and avoid gaps. Only then will mineral wool increase its insulation capacity and protect the interior space of the building.
