"Which company for seismic dampers is the best?" "I would like an introduction to seismic dampers in a ranking format." We sometimes receive such requests. However, seismic dampers vary in their compatibility with different housing structures and installation conditions, making it unrealistic to simply rank them. Moreover, the total cost fluctuates based on the main price, the number required, and the installation method, so it is not possible to determine superiority based solely on price. Therefore, in this article, we will organize the key perspectives to consider when comparing companies and products for seismic dampers, and provide a detailed explanation that includes considerations on pricing and points to reduce costs. If you want to know "how to choose without making mistakes" rather than a ranking, please read until the end. *For detailed content of the column, you can view it through the related links.

Seismic performance is an invisible quality, so when building a house, some people may wonder, "Is the highest grade seismic classification of 3 meaningless?" To conclude, seismic classification 3 ensures the strength of the structural framework against earthquake shaking, so it is indeed meaningful. However, since there is a limit to the seismic impact that a house can withstand, it is important to combine it with "vibration control performance" that absorbs earthquake shaking to create a well-balanced home. This time, "Tokiwa System," the manufacturer of the vibration control device "α Damper ExII," will clearly explain how to build an earthquake-resistant home.
