LPS 1175 Security Rated

Jakoustic® Class 3| Security Rated Fencing

Jakoustic® Class 3 is the only reflective acoustic barrier fence system certified to LPS 1175 SR3 and provides resistance to determined entry using a range of tools including battery power tools. The double layer of timber boards results in a totally flat face making climbing the fence extremely difficult and is ideally suited to applications requiring a natural timber façade, where privacy is important, or for the containment of noise into or out from a site.

Jakoustic® Class 3 LPS 1175 SR3 meets the recent guidance within ‘Physical Mitigation’ measures issued by the National Counter Terrorism Security Office (NaCTSO) to cover assets from view, making observation into a site more difficult. 

25 year service life guarantee
