dBA US-Cork

Product catalog summary

Product Overview: dBA US-Cork is an agglomerated cork product combined with a recycled polyurethane resilient layer designed for impact noise insulation in floating screed applications. It is specifically used under concrete slabs to prevent the propagation of impact sounds, such as footsteps, through a building's main structures. The product's undulated design enhances its sound insulation efficiency, particularly at mid and high frequencies.

artnovion dBA US-Cork Floor Underscreed Description dBA US-Cork is an agglomerated cork with recycled polyurethane resilient layer for impact noise insulation of floating screed. This underscreed is installed under concrete slabs so it prevents impact sounds generated by footsteps, for example, from propagating through the building's main structures. The undulated design makes it easier to deform, hence improving the material's sound insulation efficiency at mid and high frequencies.
