The Tectonic Headtrack allows for the top of full-height walls to meet multiple performance criteria. It deals with inter-storey drift and vertical deflection between two structures effectively while not conceding acoustic and fire performance.
Slots in the vertical and horizontal plane of the head track are designed to allow for building deflection and inter-floor movement caused by seismic activity and dead/live loading. Wall junction details have been developed and tested to reduce damage to the wall due to seismic and building drift.
Acoustic:
An acoustic assessment was carried out on a wall system with a Tectonic Headtrack to evaluate the performance in a partition system. A high-density passive fire protection strip was fitted to both sides of the track in the specially designed recess. Sound intensity measurement showed that on a STC 52 wall there was no reduction in the overall acoustic performance of the partition. Where a fire rating is not required, a high mass filler strip can also be used, of between 4 – 5 kg m². Test report available on request.
Fire testing:
The Tectonic Headtrack is defined as a control joint, therefore, when it is used in a fire rated system, the correct passive fire protecting must be employed. Tectonic Headtrack has been fire tested to with AS 1530.4-2014 Methods for Fire Test on Building Materials. Although the detailing is up to the fire engineer, we recommend two passive fire protection systems: RyanFire Batt 502 and RyanFire Graphite Strap.
