BOX IN A BOX construction

The Box-in-a-Box concept represents the ultimate soundproofing solution, engineered to achieve exceptional noise isolation by addressing both airborne sound transmission and impact noise. This advanced system is based on a fully decoupled structure, ensuring that vibrations and sound waves are not transferred between adjoining spaces. A Box-in-a-Box system is a delicate acoustic construction that must remain homogeneous, as even the slightest weak point can compromise its soundproofing effectiveness. To quantify its performance, Sound Transmission Class (STC) or Weighted Sound Reduction Index (Rw) ratings are used. These ratings, measured in decibels (dB), indicate how effectively a structure attenuates sound across a range of frequencies. For high-performance soundproofing, a minimum rating of STC 60 / Rw 60 dB is required—this means that a 90 dB noise source in one room would be barely audible in an adjacent space, where background noise levels typically average 30 dBA. Our innovative Box-in-a-Box system is designed to exceed standard soundproofing expectations, achieving up to 75 dB of attenuation even in spaces with openings such as doors and glass partitions. These results have been independently measured and verified according to ISO 140-4 and ISO 717-1 standards across multiple successfully completed projects.
