Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS) insulation that has various applications in construction, packaging, and arts and crafts.
Styrofoam was invented by Dow Chemical Company in 1941.
Initially used as a replacement for balsa wood in life rafts during World War II.
In 1954, Dow started producing Styrofoam for insulation purposes.
In the 1960s and 1970s, Styrofoam became popular for packaging and arts and craft applications.

Styrofoam is a closed-cell extruded polystyrene foam (XPS) insulation made from polystyrene, a type of plastic.
The R-value of Styrofoam insulation varies depending on its thickness and density. Generally, it ranges from 3.6 to 5.0 per inch.
Styrofoam is not easily recyclable in most curbside recycling programs. However, some recycling companies accept Styrofoam and reuse it for new products.
Styrofoam insulation can increase energy efficiency, reduce noise, and resist moisture and mold.
Styrofoam is not recommended for food packaging as it is not microwave safe and may leach chemicals into food when heated.
