HUSH-Mesh Firewire


Hush-Mesh Firewire is used in conjunction with Hush-Slab 100 Sound Absorber, to create a 1 hour fire resistance at ceiling level. Hush-Mesh Firewire enables work to be carried out from above in situations where the appropriate fire resistance cannot be applied to the ceiling side of the separating floor.


  • Creates a one hour fire resistance used in conjunction with Hush-Slab 100 within a timber joisted separating floor.
  • Ideal for use above lath and plaster ceilings or where work can only be carried out from above.
  • Compatible with a range of Hush®-Systems, designed to exceed the current Building Regulation requirements of Part E (England and Wales), Section 5 (Scotland) and Part G (Northern Ireland).
