Acoustic underlays are soundproof flooring materials used with most common flooring coverings to specifically reduce the impact sound, suited to a wide range of finished flooring surfacing including timbers, laminated, bamboo, ceramics, marble, vinyl, carpets.

Acoustic underlays are environmentally safe, remain permanently elastic, available in prefabricated roll, sheet rolls or sheets in thickness from 3mm to 20mm to meet various acoustical requirements for excellent results in floor isolation and superior sound control.

Applications

  • High-rise buildings
  • Hotels
  • Houses, apartments and condominiums
  • College dormitories
  • Classrooms
  • Schools

Features & Benefits

  • Green, environment-friendly soundproof flooring
  • Excellent impact sound deadening in residential and commercial floors
  • Permanently resilient
  • Suitable for loose lay and direct stick applications
