Notes:
. Values have been calculated using the allowable “Stress Design” method, taking self weight, imposed loads (wind load) and temperature (Δt=±20ºC) into account.
. If loads are effected as downwards l/200 and l/150 , ıf loads are effected as suction l/150 deflection limits have been used
. Values have been calculated using the steel quality fγ=240 Mpa(Yield Strength).
. In Panel weight calculations, Rockwool density is taken as 100 kg/m3.

Building elements resist to the airborne sound transition with their masses. Therefore as the weight of a wall increases, the loss of passage increases. However to supply sound insulation by thicken the wall is not functional and economical cause of the load that brings to the carrier system, formation of sound bridges and loss of space.
