EPS (Expanded Polystyrene) sheets are a versatile and popular material used in a variety of applications, from insulation to packaging. If you’re considering using EPS for your next project or product, it’s important to understand its properties, benefits, and how it compares to other materials like PIR (Polyisocyanurate). In this article, we will explore the characteristics of EPS polystyrene sheets, their uses, and how they stack up against other insulation materials. Let’s dive into everything you need to know about EPS polystyrene sheets.
What is an EPS Sheet?
An EPS sheet is a type of expanded polystyrene foam that is lightweight, durable, and offers excellent insulation properties. It is made by expanding polystyrene beads using steam, creating a foam structure with millions of tiny air pockets. These air pockets make EPS sheets highly effective at retaining heat and sound, making them ideal for insulation in construction and packaging. EPS sheets are available in various thicknesses and sizes, including options such as the Polystyrene Board 50mm for more specific applications.
EPS sheets are widely used in building construction, as well as in the packaging industry to protect fragile items during transportation. These sheets are also an eco-friendly choice, as they are recyclable and can be reused in certain applications.

What is the Difference Between EPS and Polystyrene?
While EPS and polystyrene are related, there is a key difference between them. Polystyrene is a type of plastic that exists in two main forms: solid and foam. EPS, or Expanded Polystyrene, is the foam version of polystyrene. The EPS foam is created by expanding polystyrene raw material to beads using steam, resulting in a lightweight, air-filled material that is more insulating than solid polystyrene.
In short, all EPS is polystyrene, but not all polystyrene is EPS. The expanded form (EPS) offers significantly better insulation properties, which is why it is commonly used for thermal insulation and lightweight filling in construction and packaging industries.
Which is Better, PIR or EPS?
When comparing PIR (Polyisocyanurate) and EPS, each material has its unique benefits. PIR is another type of thermal insulation material that is known for its high thermal resistance. It is typically used in high-performance insulation applications due to its superior R-value (thermal resistance) per cm of thickness.
However, EPS polystyrene sheets offer a more affordable and accessible solution, making them a popular choice for both residential and commercial building insulation. While PIR may provide good insulation in specific applications, EPS is more cost-effective, making it a better choice for those looking for high-performance material with value for money without compromising on insulation properties.
For example, if you need thermal insulation boards that offer both high performance and affordability, EPS sheets are a suitable choice. Formainsulation, a trusted name in insulation materials, offers a wide range of EPS products designed to meet various insulation needs.
Expanded Polystyrene Blocks

Expanded polystyrene blocks are large, dense blocks of EPS material that are used in a variety of applications, particularly in construction and Geofoam. These blocks are often used to create insulation panels for walls, roofs, and floors, providing high thermal insulation solutions. They can also be cut into custom sizes and shapes to be utilised in a wide range of lightweight filling applications according to the project requirements.
EPS blocks are lightweight, easy to handle, and cost-effective, making them a popular choice for large-scale construction projects. The blocks can be used in residential and commercial buildings, as well as landscaping projects. They are often chosen for their lightweight nature, high compressive strength, and environmental benefits, as EPS is an eco-friendly material.

EPS Polystyrene Sheets Price
The price of EPS polystyrene sheets can vary depending on factors such as thickness, size, and quantity. Generally, EPS is considered a cost-effective insulation material when compared to other options like PIR. The price of EPS polystyrene sheets is also affected by the desity and the specific properties of the material. For instance, thicker sheets or those with specialized characteristics, such as increased density or enhanced fire resistance, may cost more.
When buying EPS polystyrene sheets, it’s important to consider not just the price, but also the long-term benefits, including energy savings from better insulation and lower heating and cooling costs. Formainsulation offers competitive pricing for its EPS products, making it an affordable option for residential, commercial, and industrial applications.
EPS Polystyrene Sheets Cost
When evaluating the cost of EPS polystyrene sheets, it’s important to recognise their distinct economic advantages over other insulation materials such as PIR. EPS is typically more affordable, offering substantial cost savings without sacrificing quality or performance. This price differential makes EPS an especially attractive choice for large-scale construction projects and budget-conscious developments.
What sets EPS apart is not only its cost-effectiveness but also its efficient thermal insulation and high compressive strength properties. Despite being more affordable, EPS maintains its ability to significantly enhance energy efficiency, reduce heating and cooling costs, and provide excellent thermal insulation. These qualities ensure that EPS is a wise investment for both new builds and renovation projects using EIFS External Insulation Finishing System aiming to optimise cost while still meeting thermal insulation performance requirements.
For those seeking a balance of high-quality insulation at a competitive price, FORMA Insulation, a prominent supplier of EPS polystyrene sheets and Blocks, offers an extensive selection of products that combine durability with affordability.
