Introduction

Sika Danmark A/S (Sika Cufadan) is one of the world leaders in the development, manufacture and supply of a complete range of marine primary deck coverings, fire rated and sound reducing flooring systems for the reduction of airborne noise and damping of structure borne noise under the brand name SikaFloor® Marine.

As a member of the Swiss Sika Group, the service package includes a comprehensive range of structural sealants and adhesives for cruise ships, ferries, leisure boats, luxury yacht, commercial ships and offshore equipment manufacturing yards. This extensive line of marine products – Sikaflex® – covers all of your caulking, levelling, bedding, protecting, sealing, bonding and glazing needs.

We offer simple solutions that provide efficient and effective results at very competitive prices. The unique features of our products are setting new standards for weight reduction, noise reduction, thermal insulation and fire resistance.

Primary Deck Coverings

SikaFloor® Marine S-110 Lightweight Deck Covering
SikaFloor® Marine KG-202 Lightweight Underlay
SikaFloor® Marine KG-204 Standard Underlay
SikaFloor® Marine KG-404 Quick Drying Underlay
SikaFloor® Marine Thermo-Light Lightweight
SikaFloor® Marine E-43 Epoxy Deck Covering

S-110 Lightweight Levelling Compound

SikaFloor® Marine S-110 is a single component, lightweight deck covering with a density of 0,9 g/cm3 used in thicknesses up to 10 mm.

SikaFloor® Marine KG-202 is a multi component, lightweight underlay, with a density of 0,9 g/cm3, used in thicknesses from 8 mm and up. With densities this low, substantial weight savings are obtained over
conventional products.

SikaFloor® Marine KG-204 is a fast curing multiple-use underlay with a density of 1,2 g/cm3, used in thicknesses from 8 mm and up.

SikaFloor® Marine KG-404 is a standard multiple underlay, with a density of 1,4 g/cm3, used in thicknesses from 8 mm and up.

SikaFloor® Marine Thermolight is a lightweight thermal insulation underlay, with a density of 0,6 g/cm3, used in thicknesses from 10 mm and up.

SikaFloor® Marine E-43 Strö is both an epoxy primer and a deck finish material for wet room areas, with a density of 1,2g/cm3 (unfilled) 1,5g/cm3 (filled).

Constructions for vibration damping and sound reduction

The comfort requirements are steadily being increased, setting new standards for the maximum allowable noise and vibration level onboard ships. Regardless whether we are talking about cruise ships or working vessels, the new requirements have been introduced to protect passengers and seamen against noise.

Even though the noise sources on today’s ships are equipped with the most effective means of reducing the transmission of noise and vibration, it is experienced that a sufficient noise reduction cannot be obtained without additional noise reduction on the steel deck and bulkheads. Sound reducing and damping solutions are required to meet today’s standards. These solutions are described below.

Constrained visco-elastic vibration damping systems

SikaFloor® Marine PK-90 Alu

PK-90 Constrained Visco construction

The PK-90 constrained visco-elastic damping construction applied on top of the deck plates is the solution to reduce the radiated sound power from the deck.

The resonant vibration of the deck is decreased by increasing the loss factor of the deck construction.

SikaFloor® Marine PK-90 systems provide an extremely high sound reduction, which by far exceeds all similar systems. The ILv (Insertion Loss) in dB re 10-9 m/s is 14-19 dB largely throughout the entire frequency area. This unique vibration damping construction consists of SikaFloor® Marine PU-Red viscoelastic damping layer and steel or Alu tiles or SikaFloor® Marine KG-303 compound as constraining layer.

Sound Reducing Floating Floors

SikaFloor® Marine Litosilo (A-60)
SikaFloor® Marine Litosilo Light (A-60)
SikaFloor® Marine Litosilo Steel (A-60)
SikaFloor® Marine Litosilo Alu

The SikaFloor® Marine Litosilo and the SikaFloor® Marine Litosilo Light (both A60 with only 20 mm mineral wool). SikaFloor® Marine Litosilo Light (A60) is a similar product to the well known SikaFloor Marine Litosilo. The product offers easy application and low weight 22,5 kg per m2 (excl. Rockwool® marine slabs).

The SikaFloor® Marine Litosilo Steel construction is unique, as it is a combination of a constrained visco construction and a floating floor construction. This combination provides extremely high sound reduction
in the low frequency area as well as in the high frequency area.

The marine slabs are specially developed, thus they provide a significant improvement compared to conventional marine slabs.

The SikaFloor® Marine Litosilo system provides a very good sound reduction effect (impact and structure borne) with very low building heights from 45 mm.

Increasing demands made by regulatory authorities, ship owners and passengers with regard to the noise level on board the ships can only be met by a global evaluation of the build up principles of the accommodation.

In the noise sensitive areas there will be a need for noise reducing measures, such as insulation, noise reducing floorings and general low noise accommodation design principles.

Special attention should be given to areas in the vicinity of the engine room, propulsion system, above discotheques, below areas with high level of human activities, etc., as these areas are especially exposed to both airborne, impact and structure borne noise.

A suitable floor construction with good noise reducing properties throughout the frequency range, and especially in the low frequency range, is the combined visco-elastic and floating flooring systems. Our visco-elastic systems are also used under teak decks to reduce the propagation of impact noise to the below areas.

Fire rating

With the exception of the Alu solutions all SikaFloor® Marine Litosilo systems and combination systems are A60 Class approved according to the latest IMO testing standards for “A” Class division, fire integrity.

Approvals

All SikaFloor® Marine products are Wheelmark approved according to Council Directive 96/98/EC on Marine Equipment and also approved by major authorities, including US Coast Guard as well as by the leading Classification Societies, in compliance with the IMO rules.
