HOW SUPERYACHTS DO IT
Several kilometres of Silomar are used on each project. Silomar is a closed cell foam with a high degree of springiness, and available in a range of dimensions.
Several suppliers also provide acoustic plywood sheets, which are reassuringly expensive but very effective, and are now becoming more used widely in housebuilding. The central filling of this ply is usually a dense, lead-impregnated rubber which deadens sound between decks.
the deckhead linings of a superyacht can float too. here’s a rubber mounting plate for a suspended ceiling on a 150ft Sunseeker. note the lack of bolts holding it up – a powerful adhesive is used instead. decorative panels will be attached to the grey wooden beams using plastic clips
a cross section of a typical floating floor. the plywood’s built-in sound barrier can be clearly seen, and neighbouring sheets have been joined with a rebate to ensure no sound gaps. the whole thing rests on a bed of blue Silomar foam
