Extruded Polystyrene Insulation Boards (EPS Boards)
Expanded polystyrene insulation or EPS insulation is manufactured using a mould to contain small foam beads. Heat or steam is then applied to the mould, which causes the small beads to expand and fuse together. This manufacturing process does not form a closed cell insulation as there can often be voids between each of the beads where they are not touching one another. EPS insulation features an impressive R-Value and, generally, is more budget friendly than extruded polystyrene.
What are EPS Extruded Polystyrene Insulation Boards?
EPS extruded polystyrene insulation boards are a type of insulation material known for their efficiency and cost-effectiveness. Made from expanded polystyrene, these boards are produced by expanding small foam beads in a mould using heat or steam. This process causes the beads to fuse together, forming a lightweight yet sturdy insulation material.
Whilst these boards aren’t completely closed-cell (meaning there can be tiny gaps between the beads), they still offer excellent insulation properties. A key feature of EPS insulation is its impressive R-Value, indicating strong resistance to heat flow, which enhances energy efficiency in buildings.
EPS boards are versatile and can be used in various applications, including floor, wall and roof insulation. They’re particularly popular due to their lightweight nature, making them easy to handle and install. Additionally, they’re 100% recyclable, aligning with eco-friendly building practices. Flood resistance is another notable property, providing peace of mind in areas prone to water exposure.
EPS extruded polystyrene insulation boards are an effective, eco-conscious choice for insulation, offering a balance of performance, durability and environmental sustainability. At Workplace Interior Shop, we provide a diverse range of insulation solutions, tailored to meet various needs. Whether you’re refurbishing an existing structure or insulating a new build, our selection is crafted to deliver superior thermal efficiency and ease of installation, ensuring your project benefits from top-quality, sustainable insulation solutions.

Is EPS or XPS better for insulation?
When comparing EPS (expanded polystyrene) and XPS (extruded polystyrene) for insulation, both materials have their unique advantages. The choice often depends on specific project requirements. EPS is known for its cost-effectiveness and high R-value per pound, making it an efficient insulator. It's also lightweight, easy to handle and can be recycled, appealing to eco-conscious projects. Its breathability makes it less susceptible to moisture retention, reducing the risk of mould growth. XPS, on the other hand, typically offers a higher R-value per inch than EPS, meaning it can provide slightly better insulation in thinner applications. It's also more moisture-resistant than EPS, making it a preferred choice in environments where water exposure is a concern. however, XPS tends to be more expensive.
-
How thick should EPS insulation be?
The ideal thickness of EPS insulation depends on several factors, including the specific insulation requirements of your project and the climatic conditions of the area. Generally, the thickness can range from 25mm to 150mm, as seen in our product range at Workplace Interior Shop. For most standard applications, a thickness between 50mm and 100mm is typically sufficient to provide effective insulation. In colder climates or for buildings with higher energy efficiency requirements, thicker options, such as 120mm to 150mm, may be more appropriate. It's important to note that the chosen thickness should align with the building regulations and energy efficiency standards relevant to your project. Consulting with a professional or referring to local building codes can guide you towards the most effective thickness for your EPS insulation needs.
-
Does EPS need a vapour barrier?
Whether EPS insulation requires a vapour barrier largely depends on the specific conditions of your project. In many cases, EPS doesn't necessarily require a separate vapour barrier due to its breathability and low moisture absorption rate. In environments with high humidity or in specific building applications where moisture control is a crucial factor, however, incorporating a vapour barrier can be beneficial. It helps in preventing moisture from penetrating the building envelope, thus protecting the structure and the insulation from potential dampness and related issues like mould growth. It's essential to consider the overall design of your building, the local climate and the specific placement of the insulation when deciding on the need for a vapour barrier. In some cases, local building regulations may dictate the necessity of a vapour barrier with EPS insulation. We recommend consulting with a building professional or referring to relevant building codes to determine the best approach for your insulation project, ensuring it meets both performance and regulatory requirements.
-
Can you walk on EPS insulation?
EPS insulation isn't designed for bearing heavy loads, such as direct foot traffic. While it possesses good compression properties, it's primarily intended for thermal insulation and not as a load-bearing surface. Walking directly on EPS insulation boards, especially without proper covering or support, could lead to damage or deformation of the material. This can compromise its insulative properties and overall effectiveness. For areas where foot traffic is expected, it's advisable to protect the EPS insulation with a sturdy layer, such as plywood or a similar material, to distribute the load and prevent damage. This approach ensures the longevity and efficiency of the insulation while maintaining safety.
-
How long does EPS insulation last?
EPS insulation is known for its durability and longevity. When installed correctly and protected from direct exposure to sunlight and mechanical damage, it can last for the lifetime of the building, often exceeding 50 years. Its inert nature means that EPS does not degrade over time under normal conditions. It maintains its thermal properties and structural integrity, ensuring long-term efficiency and performance. Additionally, EPS is resistant to moisture, rot and mould, further contributing to its lifespan. Regular checks and maintenance of the building envelope can help in preserving the condition of the EPS insulation. At Workplace Interior Shop, we assure our customers that our EPS insulation products are designed for lasting performance, providing reliable and effective insulation for many years.
