PhoneStrip decoupling strips & shadow gap

The challenge: sound paths.

A solid wood or wooden beam ceiling cannot usually fulfil the building acoustics requirements on its own or as an exposed ceiling due to its low mass per unit area and the numerous structure-borne sound bridges. A sound source in the room creates a state of vibration in the partition wall that is transmitted to all neighbouring components. To reduce the transmission of structure-borne and airborne sound between the wall and ceiling, a decoupling layer must be installed.

The PhoneStrip reduces the flanking transmission of airborne and structure-borne sound through internal friction. The loose structure of the quartz sand used in the PhoneStrip provides ideal conditions for high internal damping. This leads to a demonstrable reduction in sound transmission and flank transmission.

Use in timber construction: 
As a load-transferring and settlement-resistant insulating strip that is used universally as a sound-insulating decoupling layer and as a shadow gap.

Use in concrete construction:
As a load-bearing decoupling layer for classic solid construction. PhoneStrip can absorb the ceiling deformation (ceiling deflection) that is dangerous for the masonry.

Technical data:

PhoneStrip load-bearing sound insulation strips are made from environmentally friendly materials, corrugated cardboard and quartz sand, and are specially equipped for use on the construction site.

• Ecological base materials wood and sand
• Acoustic decoupling is load-independent
• No risk of confusion - universally applicable
• Simple dimensioning
• Particularly effective in the low-frequency range
