Notes:
. 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 allowable “Stress Design” method, taking self weight, imposed loads (wind load) and temperature (Δt=±20ºC) into account.
. 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.

Acoustic panel which is formed of Steel+Acoustic Tulle+Perforated Steel and light but durable, is produced to supply sound absorption inside and sound insulation between inside and outside of the steel structured and industrial buildings. It is aimed to prevent echoing of the sound by the perforation on the sheet surface. In addition to its acoustic properties, cause of the rockwool insulation, Acoustic Panel also supplies heat insulation and fire protection.
