Description

The Sika® AcouBond® System consists of a mat in two different thickness and an elastic, sound dampening single part polyurethane adhesive in three different versions.

It is used to bond solid wood boards, three ply engineered wood as well as chipboards (groove and tongue) in new constructions and especially for renovations in residential, office and industrial buildings, as well as sales and show-rooms.

Features/ Benefits:

  • Footfall sound reduction up to 18 dB (DIN 52 210).
  • Woodfloor bonded directly to subfloor.
  • No outwearing of mat.
  • Can be walked on during installation.
  • Quick and easy to lay (designated system).
  • Low adhesive consumption.
  • Suitable for common types of wood floors.
  • Suitable for bonding wood floors directly onto old tiles.
  • Reduces stress on the substrate.
  • Compensation of small substrate unevenness.
