12 blocks of .9lb Virgin EPS 16” x 48” x 48” were used to build this floating dock and swim platform in South Hadley, MA. Un-encapsulated EPS floats are less expensive than standard encapsulated dock floats and are commonly used on private lakes and ponds. On larger bodies of water under the control of private associations and government agencies, encapsulated floats are typically required. At Universal Foam Products we provide a variety of encapsulated top mount floats and flange mount floats as well as un-encapsulated EPS floats and Styrofoam Brand flotation billets.
