    • STYROFOAM™ Brand Buoyancy Billets are an excellent choice for floating structures
      • Large blocks of lightweight, moisture-resistant, rigid extruded polystyrene foam
      • Buoyancy Billets are composed of millions of tiny air cells, each one acting as an independent buoyancy chamber
    • Applications: Floating docks, rafts, boat wells and boathouses
    • Styrofoam costs less to install
    • Simply cut with a hand saw and fasten into place
    • Won't lose buoyancy even if punctured
    • Unaffected by salt or fresh water
    • Won't waterlog, rust or corrode
    • Resistant to damage from destructive marine growth
    • Just one cubic foot (0.03 cubic meter) of billet can float up to 55 pounds (25 kilograms)
