Permafloat® Dock Floats are premium-quality, durable, and can be easily attached to nearly any new or existing wood, steel, or aluminum dock system. Cellofoam rotationally molds each Permafloat® with a nominal 0.150 inch thick walls using virgin polyethylene with ultraviolet inhibitors to make the floats extra durable to withstand damage from harsh marine environments. Permafloat® Dock Floats are filled with expanded polystyrene foam for superior buoyancy, and the rugged shell encapsulates the foam to protect the marine environment. The floats are suitable for both residential and commercial applications, and are backed by a 15-year limited manufacturer warranty.

Cellofoam was a pioneer in the encapsulation of EPS foam in docks to protect the environment. We have taken this environmentally friendly stance one step further by refusing to sell EPS foam for unencapsulated dock flotation.
