Perforated Acoustic Glass Wool Sandwich Panel

In contrast to ‘normal’ sound insulation sandwich panels, acoustic sandwich panels are also sound-absorbing. We also call them perforated sandwich panels, because there is a perforation in the steel top layer.
 

This perforation not only stops sound, but also dampens it. Since the core of an absorbent glass wool is sound attenuated.

Sound-absorbing sandwich panels help to reduce reflections. This panel is also ideal for counteracting reverberation.

By using perforated sandwich panels, you kill two birds with one stone. This is because you can build a sandwich panel wall that both insulates and absorbs.
 

 Perforated Sandwich Panel includes :  the external layer is : Perforated steel plate or aluminum plate with the openning of 3mm, the internal is galvanized steel plate or aluminum plate+cement board , the core material is high density rockwool panel and PU foam+Non woven fabric  as below drawing.
 

In order to decrease the sound spreading around from the venues with a noise source, Acoustic Sandwich Panel ensuring perfect sound insulation by absorbing the sound is the correct choice.
 

You can use the sandwich panels with acoustic features on the roof and walls of your building, as well as for the interior walls and ceilings. The fact that the perforated inner surfaces are vapour permeable limits the usage of acoustic panels in the humid environments of heated buildings.
 

Produced at various thicknesses ranging from 50 mm to 200 mm, acoustic sandwich panels control the noise in the industrial buildings thanks to their mineral wool insulation core and perforated sheet surface, and create comfortable spaces at the gyms and movie theatres by ensuring perfect acoustic sound insulation.
 

Ensuring fire resistance along with sound-thermal insulation thanks to their mineral wool insulation core, the lightweight, economic, and easily applicable acoustic sandwich panels offer smart solutions for your buildings.
