Hush Retrofit Panel

Suitable for:

  • domestic
  • residential
  • industrial
  • education

Hush RetroFit Panel is an innovative multi purpose board that contains high levels of mass to ensure optimum acoustic improvement to airborne noise issues in existing buildings.
This unique board has been designed to ensure to optimise airborne noise reduction without adding much depth to existing floors, walls or ceilings. The Hush RetroFit Panel has a unique sand infill which significantly reduces airborne noise due to its high mass levels. When coupled with an impact layer on a floor it significantly improves impact performance also. This versatile product can be used on separating floors, walls and ceilings to significantly reduce noise nuisance issues from a neighbouring space.

For advice on the use of Hush Retrofit Panel, as part of a system within any project, please contact our experienced technical team on 0151 933 2026 who will be happy to give comprehensive and practical advice to meet with your requirements.
