AYRLITE 2071 - 1

AYRLITE 2071 Acoustic Honeycomb Panel DESCRIPTION AYRLITE® 2071 is a revolutionary fibre-free, lightweight sound absorbing aluminium honeycomb panel. It is faced on one side with a flat micro-perforated aluminium sheet (AYRLITE® 2071 | FLAT) or with a corrugated microperforated aluminium sheet (AYRLITE® 2071 | CORR). The panel has outstanding sound absorption, particularly at low frequencies. The sound absorption properties are unique and remarkable for such a low weight and fibre-free material. Being all-aluminium, AYRLITE® 2071 has very good fire performance. Health and safety features are also excellent because there are no loose fibres. Although principally developed for high-performance marine vessel interior applications, AYRLITE® 2071 is also attracting interest in other marine sectors, restaurants, construction and mining industries. • Fully compliant with European Union Marine • Outstanding sound absorption especially at low frequencies Equipment Directive (EU-MED) 96/98/EC. May be used on vessels constructed, registered or operated in the European Union • Free of any fibrous or dust producing materials • Low weight, high stiffness & easy to fabricate • DNV Type Examination Certificate, for C-Class applications (on SOLAS and HSC vessels) • Fully Recyclable; all-aluminium • DNV Type Approval, for C-Class applications (on SOLAS • Standard panel thickness is 40mm.

SOUND TRANSMISSION LOSS As well as outstanding sound absorption capabilities, AYRLITE® is also very good for Sound Transmission Loss. The Sound Reduction Index to ISO 717.1 for the AYRLITE® | FLAT and AYRLITE® | CORR can be found in the graph below. The Transmission loss can be even further improved by embedding Quadzero® or similar material into the panel.
