Crown Navy Board

Short Description
Crown Navy Board is manufactured from shot free, non-combustible glass mineral wool to provide a rigid board. It is faced with a tough, puncture resistant woven glass cloth and backed with a white glass tissue. Crown Navy Board is used for the thermal and acoustic lining of bulkheads, decks and other internal primed steelwork structural surfaces in Admiralty shipping and similar marine and offshore applications where Defence Standard 02-802 (NES 802) Part 1applies.
Standards
Crown Navy Board is made from inorganic glass wool, defined as mineral wool in BS 3533. Crown Navy Board is manufactured under a BS EN ISO 9001: 2000 Quality System assessed by BSI. Crown Navy Board has a Class 1 surface spread of flame to BS 476 Part 7.
Facings
Crown Navy Board facing is factory applied and comprises a white, woven glass cloth of approximately 440 g/m² which conforms to Defence Standard 02-802 (NES 802) Parts 1 and 5. The backing is also factory applied and comprises a lightweight glass tissue of 35g/m² which provides a suitable surface to ensure consistent glue rates. At butt joints and internal and external angles, where the glass cloth facing is not continuous, it should be reinforced with a 50mm wide strip of glass cloth tape. In areas subject to high wear, metallic cladding is usually used, bonded to Crown Navy Board with epoxide adhesive.
Acoustics
Because of the acoustic absorbent nature of the product, Crown Navy Board will contribute significantly to the reduction of reverberant noise within an area and will also make a contribution to the reduction of transmitted noise between areas.

Permanence

Crown Navy Board is rot proof, odourless, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. Crown Navy Board is dimensionally stable under varying conditions of temperature and humidity and is compatible with all surfaces on which it is likely to be used in normal applications.

Form and Dimensions

Crown Navy Board is supplied as 900mm x 600mm slabs in thickness of 25 and 50mm (all dimensions are nominal). Other sizes and thickness may be available subject to enquiry.
