Reducing Boat Engine Noise

Our SA25FF/B/6 Foam Barrier composite acoustic insulation originally designed for boat engines is the perfect solution to reduce noise pollution from enclosed areas where a high degree of sound proofing is required. Combined with resistance to wear and tear, the insulation incorporates a black polyurethane face that is a tough, oil and water resistant skin protecting the insulation, yet gives effective sound absorption wherever internal engines or hydraulic power packs are used without the problem of liquid or dust contamination.

Originally designed as inboard boat engine sound insulation, this versatile product has a wide variety of other uses where a reduction in noise is required.  Comprising a mineral loaded soundproofing mat sandwiched between two layers of sound absorbing foam, this very efficient sound absorbing insulation is finished with a very tough, impermeable black polyurethane skin resistant to most fluids associated with petrol and diesel engines.

SA25FF/B/6 is easily cut to shape when required and can be installed using our special contact aerosol adhesive.  A self-adhesive version of this material is not produced due to its weight.  With a mass of 5kg/m2 the special contact adhesive is more efficient but when the product is inverted, additional mechanical fixings are required as a safety precaution.

For installation into the engine compartment of a boat, the insulation should line all of the sides and the top of the bay.  If there is a possibility of fluid contamination, sealing of the cut edges can be achieved using a silicon sealant.
