10 Facts About the Impact of Moisture on Rock Wool (Stone Wool)

Even if moisture gets in, the performance of stone wool remains unchanged! 10 factors to consider.

Water is essential for human life. However, for buildings, water can often be a significant cause of problems such as mold, decay, and corrosion. In construction projects, it is important to choose insulation materials that do not absorb moisture when exposed to water. One such insulation material is stone wool. One of the key characteristics of stone wool insulation is its water-repellent property. The PDF document introduces "Four Ways Stone Wool Ensures Health and Safety," as well as the "Seven Powers of Stone" incorporated in ROCKWOOL products. Please download and take a look. [Effects of Moisture on Stone Wool (Partial)] - Does not absorb moisture when exposed to water - Does not absorb moisture in high humidity environments - There is a reason for its water-repellent property - Allows water vapor to pass through - Importance of airtight structures *For more details, please refer to the PDF document or feel free to contact us.

HK-2

Recommended for earthquake measures for automatic doors and equipment! Seismic device HK-2.

  • NEW
  • PRODUCT

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.
