Features

Lietzke Acoustic Doors are manufactured to provide sound transmission reductions where access/egress is required through walls of acoustic properties. The doors can be manufactured from various materials, each having differing acoustic properties, dependant on the STC rating required. All door constructions share a common finish being 0.55mm thick Colorbond or Galvabond steel and the units must be fitted with the appropriate accompanying acoustic seals to both door and frame. Most locking devices and hardware can be factory fitted to the door.

Applications

Any application requiring sound transmission reduction such as transformer sub-stations, plant rooms, school activity rooms and auditoriums

Finishes

Standard finish is Colorbond but may be finished in factory applied durable polyester powdercoat over Galvabond.
