Science of Silence
Halyard
This facing meets the requirements of the Recreational Craft Directive.

It provides a seal to keep oil out. You can pierce it, but it has a re-enforcing layer behind it. It will burn, but once laminated in place it meets the ISO 9094 fire requirements of the EU Recreational Craft Directive.

In a fire the facing will burn, but not the foam behind it.

Custom options are available upon request, please call our technical helpline on +44 (0) 1722 713704 for more information.
• Meets ISO9094 fire requirements

• Supplied with 4 sheets (1000mm x 600mm) per box *Except 45mm version, which is 2 sheets per box

• Available in: 12mm, 32mm and 45mm thickness levels.


12mm materials: Offers a 12dB reduction at 1000Hz and above, but its efficiency reduces with the heavier noises of lower frequencies. The overall reduction will give excellent results with smaller, lighter engines. Lightweight and offers a good choice for restricted budgets.

32mm materials: Offers a 15dB reduction at 1000Hz. Noise doubles every three decibels, so this is nearly three times as good as the 12mm. It also holds a good performance at lower frequencies, making it excellent with larger engines. Good choice for mid-price range.

45mm materials: Offers a 30dB reduction at 1000Hz and provides an excellent overall performance.

Noise insulation can only be used with care, as it must not impede the flow of cooling air. Beware of solid mounted engines. Most of the noise will be structure borne with a solid mounted engine. The same applies with a steel hull. The Aquadrive anti-vibration system can reduce noise by 75% with such installations.
12mm (1/2") Materials

All are supplied with 4 sheets 1000 x 600mm (39" x 24") per box.

These material offers around 12dB reduction at 1000Hz and above, but its efficiency reduces with the heavier noises of lower frequencies. The overall reduction will give excellent results with smaller, lighter engines.

32mm (1.25") Materials

All are supplied with 4 sheets 1000mm x 600mm (39" x 24") per box
The 32mm materials offer a startling 15dB reduction at 1000Hz. Noise doubles every three decibels, so this is nearly three times as good as the 12mm. It also holds a good performance at lower frequencies, making it excellent with larger engines.

45mm (1.75") Materials

All are supplied with 2 sheets 1000mm x 600mm (39" x 24") per box
