High Security Acoustic Fencing

Trident® Jakoustic 3 | High Security Fencing

Trident® Jakoustic 3 system is of sandwich construction comprising two facings of interlocking ‘V’ timber boards, interlined with a layer of high security steel mesh 2.28m above ground. The interlocking ‘V’ coupled to a tongue and groove locates the boards in such a way that eliminates gaps even when boards shrink and expand with changes in the weather. The totally flat attack face, high security steel mesh interlining and combination of unlike construction materials makes the fence extremely difficult to scale or penetrate.
