Description

sonus multi 3 is a tough and resilient acoustic underlay that has been developed to attenuate impact sound beneath a range of floor finishes, delivering exceptional acoustic performance without ageing or collapsing. sonus multi 3 meets the requirements of Approved Document E (England & Wales), Technical Booklet G (Northern Ireland) and Example Construction floors under Section 5 (Scotland) (on certain floors).


sonus multi 3 is also available as a fire-retardant version. 


Features and benefits:

  • Offers long term performance without collapse or “bottoming” out under high point loads.
  • Resistant to ageing and deformation.
  • Quick and easy to install - simply bond to the subfloor beneath the final floor finish.
  • Product manufactured using recycled materials and 100% recyclable.
