Rock wool

Rock wool

High heat-resistant rock wool. It is widely used in various fields, including buildings, factories, and general residences, for its fire resistance, insulation, and soundproofing properties!

Rock wool is made from heat-resistant minerals and blast furnace slag, which are melted at high temperatures and spun into fibers using centrifugal force. Nichias's rock wool products, "MG products," are designed for fire resistance, thermal insulation, and soundproofing, and are offered across a wide range of fields, including buildings, factories, and general residences. For more details, please contact us or download the catalog.

Seismic reinforcement slit material NN soft rock wool

Seismic reinforcement slit material NN soft rock wool

Renovation work for seismic resistance to ensure a safe and secure building.

There are various methods for earthquake countermeasures, and our company has developed and is manufacturing and selling seismic retrofit slit materials that are inserted between the columns cut by cutter work and the secondary walls. Buildings constructed after June 1, 1981, under the "New Seismic Design Method," are designed to include seismic slits to prevent "shear failure due to short columns." For buildings constructed before that date that require seismic retrofitting, options include brace reinforcement and cutter work. To prevent major earthquake disasters, we encourage you to consider this as one of the safety measures for existing buildings.

Insulation performance of rock wool

Insulation performance of rock wool

The more fiber strands there are, the better the prevention of insulation performance decline! We will introduce insulation performance by temperature range.

The insulation effect of "rock wool" is demonstrated by the fact that over 95% of its volume is occupied by air, which is separated into fine gaps by fibers, making it difficult for the air to move. As the temperature of the air within the rock wool rises, it becomes more active, leading to a decrease in insulation performance with the increase in ambient temperature. However, the higher the density, meaning the greater the number of fibers per unit volume, the more resistance to air flow increases, preventing a decline in insulation performance. "Roxceram" is excellent in fire resistance and can be used as an insulation material even in high-temperature areas of around 400°C, making it widely utilized under harsh conditions such as in plant equipment. For more details, please refer to the PDF download below. 【Insulation Performance by Temperature Range】 ■ Low Temperature Range (below 100°C) - It shows a minimum value with a density of 80-100 kg/m³, but there is no significant difference across the entire density range. ■ High Temperature Range (above 100°C) - Above 100°C, the thermal conductivity increases quadratically with rising temperature. - This trend becomes milder as the density increases. *For more details, please refer to the PDF document or feel free to contact us.
