Thermal-acoustic insulation DK220

polyurethane foamstone woolwood fiber

The Phonotech® DK220 element is based on the floating roof principle through its spring batten providing a mass-spring-mass effect. Due to its RD220 start and end battens, the Phonotech DK220 system forms an intuitive complete roofing assembly. This decoupling will block any transfer of vibrations through its shock absorbing effect and will provide optimum sound reduction. INSTALLATION Due to their light weight, Phonotech elements can by installed by one person alone. The intuitive Phonotech attachment system guarantees easy and fast assembly. APPLICATION The Phonotech® DK220 acoustic system can be laid both on flat roofing and sloped roofing. FINISHES Most of our acoustic systems are tested without a finishing coat (sealing, tiles, etc.) This gives the customer total freedom on the choice of roof finish to be applied.
