<p>A wall system is disclosed, which is able to significantly decrease a building cost since a wall system itself has a soundproof and vibration-damping function which does not need a sound absorption and vibration-damping structure, and which is able to decrease the unit cost of a material since homo or hetero steel sheets can be bonded with a bonding resin, and which is able to obtain a soundproof and vibration prevention effects by using a bonding resin layer which has an excellent sound absorption and vibration-damping performance with the help of a certain viscosity.</p> |
