There are several different types of insulation on the market and it can be difficult to know which is most suitable for your project. From glass wool insulation to foil-backed insulation, there is a solution available for every application. When it comes to insulation materials, expanded polystyrene insulation is a popular choice and it provides several advantages. This insulation material is widely used in various construction projects and it’s worth exploring if you’re not sure which type of insulation to use. Below we have put together some information about expanded polystyrene insulation, covering all of the basics you need to know. 

What is Expanded Polystyrene Insulation?

Expanded polystyrene insulation is a type of rigid insulation. It’s made from expanded polystyrene beads, which are heated causing them to expand significantly from their original size. During the manufacturing process, the beads are mounded and pressed into rigid boards or blocks that have a closed-cell structure. The finished product is very lightweight and has excellent thermal properties. This type of insulation is available in various thicknesses and densities to meet different insulation requirements. The thickness and density of the rigid boards determine their thermal resistance, commonly referred to as the R-value. Higher-density insulation boards generally have a higher R-value, resulting in improved effectiveness.

Why is Expanded Polystyrene Insulation Popular?

Expanded polystyrene insulation is popular for several reasons, which contribute to its frequent use in the construction industry. Some of the factors that make this insulation a preferred choice for a range of applications include; 

    Excellent Thermal Insulation – Expanded polystyrene insulation offers high thermal performance. Its closed-cell structure and air pockets effectively reduce heat transfer, minimising heat loss during winter and heat gain during summer. This results in improved energy efficiency and reduced energy bills. 

 

    Moisture Resistance – This type of insulation is known for being moisture-resistant. It doesn’t absorb water like other insulation materials, preventing mould, mildew and rot. This ensures the long-term performance and durability of the insulation, particularly in areas with high humidity or that are prone to moisture exposure.

 

    Lightweight and Easy to Install – Expanded polystyrene insulation is lightweight, making it very easy to handle. The rigid boards are available in various sizes and they can easily be cut to meet your specific construction requirements. Their ease of installation saves time and labour costs during the installation process.

 

    Durability and Longevity – This insulation material is known for its durability and long lifespan. It doesn’t degrade over time, maintaining its shape and insulating performance. This longevity reduces the need for frequent insulation replacements or repairs, resulting in long-term cost savings.

Where can Expanded Polystyrene Insulation be Installed?

Expanded polystyrene insulation is incredibly versatile and it can be used in a wide range of applications. It’s suitable for wall insulation, floor insulation, roof insulation and loft insulation, to name a few. This versatility makes it a great choice for any construction and renovation projects, and it can be installed in a variety of different types of properties. 

Is Expanded Polystyrene Insulation Expensive?

When compared to other insulation materials, expanded polystyrene insulation is a cost-effective choice. Even high-quality products are relatively low cost and the ease of installation can help to reduce overall project costs. This combined with its excellent insulation properties makes it a popular option for both residential and commercial projects. The energy savings achieved over time contribute to its long-term cost-efficiency.
