Spray foam insulation has been chosen to insulate the fish rooms of newly built shipping vessels by Parkol Marine shipbuilders for superior insulation. In order to achieve this, a seamless membrane of spray foam insulation has been applied to help reach optimum U-values.
A closed-cell spray applied polyurethane foam insulant can be used directly onto the internal surfaces in marine applications. This will insulate the vessel which is particularly important when fishermen are trying to maintain a cold environment in which the fish are kept before reaching shore again.
Initially all the hot works were completed and the shipwrights fixed all the groundings within the underside of the deck head together with the bulkheads and sides, all down to the level of the water line. Following completion of these works engineers from Hull based R&S Insulation applied the BASF Elastospray insulation system. This is a closed cell system which has achieved a Class 1 fire rating to BS 476 Part 7 for the surface spread of flame.
In order to provide a level finish with the front face of the groundings, the thickness of insulant was varied from around 300 mm to 600 mm according to the contours of the vessel. Richard Knowles and Stephen Shultz from R&S Insulation have an extremely good record for marine works with Richard being one of the most experienced engineers in this field having sprayed polyurethane foam since the mid 1970’s, but younger business partner Stephen is not far behind. R&S Insulation said that they “chose the BASF Elastospray system for its cost effectiveness, coupled with excellent supplier back-up”.
Following completion of the insulation works the area was panelled out by the shipwrights and finished with a hard, waterproof and hygienic coating.
Both R&S Insulation, the installers, and BASF, the material suppliers are members of the British Urethane Foam Contractors Association. The association represents spray foam installers for marine and other sectors and has a list of registered installers at www.bufca.co.uk.
