Sound Insulation Solution.
 
The Partition Wall - Ultimate solution takes an advantage of the weight distribution between the two wall panes. By adding more layers unevenly, it's possible to improve the performance of the whole construction, specially at lower frequencies. This solution is expected to have an Airborne Sound Reduction Index (Rw) of 56 dB.
