Seismic isolation device - Minister of Land, Infrastructure, Transport and Tourism certified shear wall 'K Damper'
Acquired a wall ratio of 3.3 times. Protecting homes from earthquakes! Maintenance-free seismic dampers!
The Minister of Land, Infrastructure, Transport and Tourism certified seismic damper, the K-Damper, is a damping device that has achieved a wall strength ratio of 3.3 times. It employs phenolic resin technology, commonly used in automotive disc brakes, to convert seismic vibrations into frictional heat and absorb them. **Features** - Certified by the Minister of Land, Infrastructure, Transport and Tourism, achieving a wall strength ratio of 3.3 times. - By installing four units per building, it can reduce vibrations by up to 76%. *Compared to a structure equivalent to seismic grade 1. - The damping material uses phenolic resin, which consistently demonstrates excellent damping performance. - Durability is over 169 years, with no degradation in performance even after 700 cycles of repeated friction. *Based on test results for ministerial certification application. *For more details, please download the catalog or feel free to contact us.

Free Online Seminar "K Damper for Wooden House Seismic Isolation Devices"
★Free Online Seminar! Don't you think earthquakes have been occurring frequently lately? From January to April 2021, there were 91 observations of medium to large-scale earthquakes with seismic intensities ranging from 3 to 6+ across the country, which is about 1.5 times the pace compared to the number of observations in the past five years. Additionally, on October 7, an earthquake with a seismic intensity of 5+ was observed in the Kanto region, the strongest since the Great East Japan Earthquake, raising the necessity for earthquake preparedness once again. According to the announcement from the Ministry of Land, Infrastructure, Transport and Tourism and its advisory body, the Earthquake Research Committee, the probability of a magnitude 8 to 9 class earthquake occurring in the Nankai Trough within the next 30 years is estimated to be 80%. In light of this situation, along with the rising desire for home ownership heightened by the COVID-19 pandemic, there is an increasing demand for "seismic control" technology as a new earthquake countermeasure among prospective homebuyers. We invite you to participate in this online seminar and consider the new earthquake countermeasure technology, the K-Damper.
