Fire Rated Stud Walls
Assessment criteria are represented by three performance measurements known as
“Fire Resistance Levels (FRL)”
- Structural Adequacy
- Integrity
- Insulation
This indicates the number of minutes that the specimen fulfils the requirements of the three fire test criteria e.g. -/60/60, 60/60/60 etc.
Peer Industries Pty Ltd steel studs are tested for FRL in conjunction with plasterboard complying with AS2588.and 1530.4 as well as the BCA
Any plasterboard can be used with Peer steel studs provided those plasterboards are manufactured to AS2588 and are tested for required FRL.
Refer to plasterboard manufacturer’s specification for required FRL.
Sound Transmission Class – STC
Peer Industries steel stud wall with plasterboard complying with AS2588 and the BCA underwent laboratory tests to establish their sound insulation characteristics.
The sound transmission loss through the stud wall was calculated for each specified frequency.
Measurements are made in one-third octave bands from 125 to 4000 Hz.
The STC rating is determined by comparing the measured sound transmission loss curve of an assembly in reference to STC contours.
Each such assembly is conveniently expressed as a single number known as STC of that assembly.
A higher the STC value indicates a better acoustic performance.
Refer to the plasterboard manufacturers specifications for required STC.
Any plasterboard can be used with Peer steel studs provided these plasterboards are manufactured to AS2588 and are tested for required STC performance.
