The seismic-resistant windows for the life I wanted! They can be used partially, the installation is clear, and they can be used not only for new construction but also for renovation work.
The "J-Seismic Opening Frame" is a seismic window that was born from the application of the mechanical idea that "the frame bears only horizontal forces without bearing vertical forces." Since it is not restricted by construction methods, it can be used partially, and the installation is straightforward, making it suitable not only for new constructions but also for renovation projects. Additionally, it has received numerous awards, and its performance is widely recognized. It is a dream frame that satisfies both "user wishes" and "building codes," evolving wooden houses. 【Features】 ■ Can be installed inside existing columns and beams, regardless of construction method ■ Can be treated similarly to structural plywood and bracing ■ The cross-section of the components remains constant even if the span changes ■ Can be installed on standard foundations *For more details, please refer to the PDF materials or feel free to contact us.
