The anti-vibration wall braces EFWB are used in order to add structural integrity of long and tall gypsum board walls, which are mounted on anti-vibration pads or based on floating floor. They avoid any direct connection between the double walls, and increase their stiffness. They prevent wall backward motion during earthquakes. It is used where a secondary wall is installed for improved sound insulation.

EFWB consists of a metal frame, suitable reinforced and modulated. Two special anti-vibration elastic support, EFWB is placed internally to absorb positive and negative axial forces. EFWB are not to be used for vertical support.
