What is the difference between polystyrene and expanded polystyrene?
The main difference between these two materials lies in their density. Extruded polystyrene is much denser than expanded polystyrene (2.18 lbs. on average for XPS vs. 0.93 lbs.
What sizes do Styrofoam sheets come in?
The common large sheets come in four Imperial sizes of 8′ x 4′, 60″ x 40″, 48″ x 36″ and 40″x 32″.
How much does EPS foam cost?
EPS Data Summary: Cost: $9 -$13(prices vary based on product specifications)
How strong is expanded polystyrene?
The mechanical strength of EPS varies with its density. The most important mechanical property of EPS insulation and building products is its resistance to compressive stresses, which increase as the density becomes higher. EPS has a compressive resistance between 10 – 60 psi for most construction applications.
Is Expanded polystyrene the same as extruded?
Expanded polystyrene is a type of foam made from polystyrene. It is a lightweight, rigid and closed cell insulation. Extruded polystyrene is another form of foam made from polystyrene. The trademark name for this product is Styrofoam (by The Dow Chemical Company).
What is the R-value of 2 inch Styrofoam insulation?
A wall utilizing STYROFOAM T-MASS Technology with a 2-inch exterior layer and a 4-inch interior layer of concrete along with a 2-inch layer of STYROFOAM extruded polystyrene insulation would result in a material R-value of approximately 11.33.
What is the difference between extruded and expanded polystyrene?
What is the Difference Between Expanded and Extruded Polystyrene? Expanded polystyrene or EPS is a thermoplastic foam material that we produce from solid beads of polystyrene whereas the extruded polystyrene or XPS is a foam material that we produce from solid polystyrene crystals.

Is expanded polystyrene safe?
Expanded Polystyrene (EPS) or Styrofoam, is a petroleum-based non-biodegradable foam, which the EPA and International Agency for Research on Cancer consider styrene a “possible human carcinogen” and “that such materials can have serious impacts upon human health, wildlife, and aquatic environment, and the economy.”
What is expanded polystyrene used for?
Expanded Polystyrene (EPS) is a rigid cellular plastic, which is found in a multitude of shapes and applications. It is used for fish boxes, packaging for electrical consumer goods and for insulation panels for building. These are the most commonly known uses and we will mention others in this document.
