Sound insulation, halogen-free and airtight in a can! With the Qnect cavity wall sound insulation device V socket, installation in drywall construction with sound insulation up to 58 dB is possible quicker than ever before. It does not matter whether they are single-sided boxes, offset boxes or opposite boxes. With a diameter of 74 mm and a depth of 62 mm, the Qnect sound insulation also offers significantly more junction space than conventional cavity wall boxes. For multiple combinations, the device junction boxes in wooden frame walls or rigid plaster can therefore also be firmly connected to each other at a standardised spacing of 71 mm. The SCS connection technology with large-area connection membrane including cable-popping technology then enables simple through-wiring without connection sockets. The Qnect cavity wall box sound insulation is also available with a depth of 49 mm.
