EPS vs. XPS: What’s the Difference?

While both expanded polystyrene (EPS) and extruded polystyrene (XPS) are types of foam insulation, there are several key differences between the two materials. Understanding these differences can help you choose the best option for your specific needs.

Production Method

The primary difference between EPS and XPS is their production method. EPS is created through a steam-driven process that expands tiny beads of polystyrene, while XPS is created through a continuous extrusion process that produces a uniform, dense foam board.

Physical Properties


Density Low to medium High
Thermal Conductivity Low to medium Low
Water Resistance Poor Excellent
Compression Strength Low to Medium High

EPS has a lower density and thermal conductivity than XPS, making it an effective choice for insulation in a variety of applications. However, XPS is more water-resistant and has a higher compression strength, making it a better option for use in applications where moisture and heavy weight loads are concerns.

Environmental Impact

Both EPS and XPS are recyclable, but the process for recycling XPS is more complex and less widely available than EPS recycling. Additionally, EPS is often made using less energy than XPS, making it a more environmentally-friendly option.

Expanded Polystyrene Blocks

Overall, the choice between EPS and XPS depends on the specific needs of your application. EPS is a versatile and eco-friendly option, while XPS provides greater water resistance and compression strength.

Is EPS Recyclable?

One of the most common questions about expanded polystyrene (EPS) foam blocks is whether they are recyclable or not. The answer is yes, EPS can be recycled, but it’s important to understand the process and limitations of EPS recycling.

EPS can be recycled by crushing and compacting the material into solid blocks, which can then be melted and re-used to create new products. However, it’s worth noting that not all recycling facilities accept EPS due to the transport and storage limitations of the bulky material.

Fortunately, there are EPS recycling programs available in many areas throughout the United States. These programs typically involve drop-off locations or curbside collection for EPS products, which are then transported to a recycling facility for processing.

It’s also important to note that while EPS is recyclable, it’s best to reduce and reuse EPS products whenever possible to minimize waste. For example, EPS packaging materials can be reused for storage or shipping purposes rather than being disposed of after a single use.

Recycling EPS is an eco-friendly option that can help reduce waste and conserve resources. By participating in EPS recycling programs, you can help ensure that EPS foam blocks are reused instead of ending up in landfills or waterways.

Is EPS Toxic?

There is a common misconception that expanded polystyrene (EPS) foam blocks are toxic. However, this is not true.

EPS is made from a thermoplastic material that does not contain any harmful chemicals such as CFCs, HCFCs, or formaldehyde. It is also free from heavy metals like lead, cadmium, and mercury.

Additionally, EPS does not emit any toxic fumes or gases when burned, making it a safe option for use in construction and packaging applications.

In fact, EPS is categorized as a “nuisance dust” by the Occupational Safety and Health Administration (OSHA) and is not regulated as a hazardous material.

Overall, EPS is a safe and non-toxic option for various applications.
