Overview
The ISOLCOL project aimed to reduce the noise and vibrations generated by pedestrian traffic on the open decks of the ship (e.g. swimming pool area) in the cabins immediately below these areas. Currently, the wood is glued on decks with a layer of viscoelastic interposed between the deck and floor to dampen noise and vibrations, but this leads to a series of problems related to the increase in combustible material on the ship, weight, costs and time for drafting and fixing. The aim of the project was to replace the viscoelastic by formulating a nano-glue including thermo-vibratory acoustic nano-insulating characteristics. This nano-glue is sprayed between the bridge and the wooden flooring in the upper part of the bridge and between the wooden flooring and the insulating panels at the bottom of the bridge. The project aimed for an improvement of the thermal and vibroacoustic insulation of the cabin, to reduce thickness and weight of the traditionally used insulation, to cut the thermal and vibroacoustic bridges constituted by the terminal part of the standard harpoons not covered by the insulation, and to the reduce outfitting time and cost.
