Interiors by INEXA Craftsmen to the world´s finest ships TNF High Noise Reduction

The QUIET around TNF accomodation systems is a reason for installing them. Many ship and rig owners specify TNF low noise products to improve their work and leisure environments, which will also be comfortably ahead of the authorities’ noise level regulations. There are three vital parameters, which determine the noise reduction you can achieve: • Ship layout. • Application of low noise sources. • Design of low noise cabins. High noise reduction is where the Inexa TNF products excel. When correctly installed, they provide maximum quiet and comfort by reducing unwanted structural and...

TNF ship interiors designed to provide complete low noise accommodations on ships The average figures (field values) achieved with TNF standard high noise reduction products and • 40-42 dB noise reduction between cabins. • 10 dBA reduction of structural noise. These values cause a considerable improvement on conventional cabin standards. For higher noise reduction values, special TNF products and designs will be used. Most modern ships and offshore platforms are constructed to low background noise Low background noise increases the need for an accommodation installation with high noise...

High noise reduction bulkhead system The high noise reduction bulkhead panel TNF 2SM has a good noise reduction value - only 50 provides real privacy insulating properties. Type 2SM wall panel construction Floating floor units. The TNF FS floating floor units have a steel surface and a underlay of specially developed insulation material. The floating floor unit provides extremely effective noise reduction and structural noise damping, which contributes to the overall quiet of any Fully insulated self-supporting ceiling With a free span up to 3000 mm, the TNF B class ceilings are the lids on...

Correct installation of TNF products is important -they are tailor made for quiet assurance in the future! Reduction of airborne sound The inherently high noise reduction values of the prefabricated TNF panel system are maintained after installation, as interior designs are tailored to ensure the best results in any type of project. The product and installation details shown are examples from TNF technical literature. Corner and T-joints Prefabrication minimizes noise penetration at the joints and noise transmission through the steel surface of the panels. QUIET panel construction QUIET...

VLD Velocity Level Difference Reduction of structural sound No hangers provide high Velocity Level Difference (VLD). Transfer of noise from ship side or steel bulkhead to the wall panels can be minimized by resting the top channels on the panels. Self supporting ceiling provides high VLD Floating floor provides high VLD Telescopic window box provides high VLD Our technical services department can assist architects and engineers by creating design proposals of their actual projects, using a 3D CAD system. The drawings serve as a basis for the contractor to ensure correct installation.

TNF is the complete high quality accommodation system for all marine interiors. The TNF system includes wall and ceiling panels, doors, floors and wetunits. TNF has been leading the development in marine interiors since 1973. The world famous TNF quality is demonstrated in the environment, which can be designed to provide the ideal conditions for all functions. TNF www.inexa.com info@inexa.com
