If you’ve think you’ve seen building sites using Styrofoam block construction, you’re probably looking at EPS (expanded polystyrene). Styrofoam is a specific brand name for flat insulation sheets despite being used as a general term. EPS blocks have high compressive strength and are lightweight and easy to handle as a void fill material used to build today’s stadium seating, auditorium and swimming pools. Blocks can be easily cut and shaped to fit large areas including level floors, tiered seating and sloped access. A huge range of regular and custom fit EPS blocks are available from Universal Foam Products.
