XPS Extruded Polystyrene Insulation Boards
Extruded polystyrene insulation or XPS insulation is manufactured through an extrusion process. This manufacturing process involves melting together the plastic resin and other ingredients. The liquid formed is then continuously extruded through a die and expands during the cooling process. This produces a closed cell rigid insulation. XPS offers thermal efficiency, as well as featuring impressive compressive strength and vapour resistance.
What are XPS Insulation Boards?
XPS insulation boards (also known as extruded polystyrene insulation) are a high performing insulation solution. Manufactured through an advanced extrusion process, these boards merge plastic resin with other materials to form a rigid, closed-cell structure. Key features include excellent thermal efficiency due to low thermal conductivity, superior compressive strength for durability and significant moisture resistance, making them ideal for both new constructions and refurbishments. Their versatile applications range from roofing and wall insulation to underfloor systems, embodying an effective, eco-friendly choice for modern insulation needs.
Is XPS Insulation Better Than EPS Insulation Boards?
When comparing XPS (extruded polystyrene) and EPS (expanded polystyrene) insulation boards, it’s important to consider their distinct characteristics to determine which is better suited for specific needs.
- Thermal Efficiency – XPS boards generally have a lower thermal conductivity compared to EPS, offering better thermal insulation. This means less heat loss in winter and reduced heat gain in summer, enhancing energy efficiency.
- Compressive Strength – XPS typically outperforms EPS in terms of compressive strength. This makes XPS more suitable for high-load applications like flooring insulation.
- Moisture Resistance – XPS boards have a lower water absorption rate than EPS. This resistance to moisture penetration makes XPS a preferred choice in damp environments or applications prone to water exposure.
- Durability – XPS, with its higher density, tends to have a longer lifespan and better resistance to degradation over time compared to EPS.
- Environmental Considerations – Both materials have varying impacts on the environment, with manufacturers increasingly focusing on eco-friendly production methods. The choice between XPS and EPS may also depend on the sustainability practices of the specific brands.
The Benefits of XPS Insulation Boards
XPS insulation boards offer a multitude of advantages for both residential and commercial properties. Their unique manufacturing process results in several key benefits:
- Exceptional Thermal Insulation
XPS boards are known for their low thermal conductivity, effectively reducing heat loss and helping maintain consistent temperatures, which can lead to significant energy savings.
- High Compressive Strength
These boards are remarkably robust, providing excellent durability and making them suitable for heavy-duty applications, such as load-bearing floors.
- Moisture Resistance
XPS boards resist water absorption, protecting structures from damp and mould, and ensuring long-term stability and insulation performance.
- Eco-Friendly
Many XPS boards are produced with sustainability in mind, contributing to the environmental efficiency of buildings.
- Versatility
Their adaptability makes them ideal for a variety of applications, including roofing, walls, floors, and even demanding environments like basements and cold storages.

-
What is the difference between XPS and extruded polystyrene?
XPS is actually a type of extruded polystyrene (it actually stands for extruded polystyrene insulation), so there isn't a difference between the two. It's a specific method of producing polystyrene insulation where the material is melted, mixed with additives and then extruded into the shape of the board. This process results in a closed-cell structure that offers excellent insulation properties, moisture resistance, and durability.
-
Is XPS better than PIR?
The comparison between XPS (extruded polystyrene) and PIR (polyisocyanurate) insulation largely depends on the specific requirements of your project. XPS is renowned for its excellent moisture resistance and high compressive strength, making it ideal for areas prone to moisture or where the insulation must withstand weight or pressure. PIR, on the other hand, boasts superior thermal efficiency and fire performance, making it a preferred choice in scenarios where thermal insulation and fire safety are paramount. Neither is inherently 'better' than the other; rather, the choice should be based on the specific needs of your insulation project. Consider factors such as the location of insulation, exposure to moisture, thermal requirements, and fire safety standards.
-
Does XPS insulation need a vapour barrier?
Generally, XPS insulation doesn't require a separate vapour barrier. This is due to its closed-cell structure, which naturally provides a degree of moisture resistance. The need for an additional vapour barrier can, however, depend on the specific conditions of your building project, such as the location of installation and the overall design of the building envelope. It's always a good idea to assess the individual requirements of your construction or renovation project. If you're unsure whether a vapour barrier is needed with XPS insulation in your specific situation, we recommend consulting with an expert.
-
What is the lifespan of XPS insulation?
XPS insulation is known for its long-lasting performance. Typically, it can last for several decades, often matching the lifespan of the building in which it's installed. Its durability is due to its moisture resistance and robust structure, which help it maintain its insulating properties over time. The exact lifespan can vary depending on environmental factors and the specific conditions of use.
