wood fiberpanelwall

The PENTAFLEX® STK sound-insulating cage is part of the PENTAFLEX® joint sealing system designed for the construction of water-impermeable concrete structures (white tank). The two-part sound-insulating cage is mainly used in semi-detached and terraced houses and is used both in element wall construction and in-situ concrete construction. It separates the solid components and thus prevents flanking sound transmission in the external walls. The sound insulation joint strip seals the joint against pressing water. Advantages Reliable sound insulation Sound insulation tested Secure sealing of the joint Simple and reliable connection to the PENTAFLEX KB® seam sheets by means of the PENTAFLEX® joint tape connection Technical Details Sound-insulating cage consisting of hydrophobic soft fibreboard with integrated steel retaining stirrups
