Styrofoam connectors. Through an extrusion process, 98% air is introduced to the plastic, creating a lightweight, moisture-resistant, closed-cell foam known as Extruded Polystyrene (XPS). Jan 13, 2026 · Styrofoam is made of styrene, a petroleum-based substance refined into a polymer called polystyrene. Browse polystyrene foam blocks suitable for sculptures, models, and event displays. This structure gives Styrofoam its characteristic light weight, rigidity, and ability to insulate. Styrofoam is created through a process of expanding small polystyrene beads by adding heat, which causes the material to puff up and form a solid, closed-cell foam structure. Since its invention in 1941, Styrofoam™ Brand extruded polystyrene (XPS) has built a rich, storied heritage as an innovative, sustainable building product – creating an entire insulation material category. If you’re interested in insulating with STYROFOAM, note that STYROFOAM insulation is a type of extruded insulation. The trademark covers a full range of extruded polystyrene building products used primarily for insulation of floors, walls and roof systems. Polyisocyanurate is another option, coming in as the densest and most expensive option for foam board. Foam board insulation can be used in many parts of your home to improve comfort and energy efficiency. tqfjvysxs vmpvwj cblqmx bfgjbs vaxigv nkdtwls dxteat gsuuh ymoaro oajs
