What is Extruded polystyrene?

Commonly known as XPS, extruded polystyrene is a versatile material that’s used across a wide range of industries. From insulation to packaging, this closed-cell foam is valued for its lightweight, durable and insulating properties. More than that, XPS is an environmentally-friendly choice, as it can be recycled and repurposed. So, next time you come across a foam cooler or a sturdy insulation board, remember you’re dealing with the magic of this material.

Benefits of Extruded Polystyrene

The followings are the top benefits of this material for your building projects.

Insulation Properties

One of the primary benefits of using extruded polystyrene for your building projects is its insulation properties. It has a closed-cell structure which helps to keep heat inside during the colder months and outside during the warmer months. It can help to lower your energy bills and create a more comfortable living or working environment.


It is water-resistant, making it an ideal choice for applications where moisture is present. It includes parts of the building that are below grade, such as foundations and basements. Its water-resistant properties ensure that the material does not get damaged by water exposure, making it an excellent choice for damp environments.


Extruded polystyrene is incredibly lightweight, weighing only 2-3 pounds per cubic foot. It makes it easier to transport and handle on the job site. Its lightweight properties also make it an excellent choice for roofing applications, where weight can be a concern.

Excellent Thermal Performance

One of the most significant benefits of using XPS insulation in your building project is its outstanding thermal performance. XPS insulation provides excellent resistance to heat flow, making it an ideal choice for both hot and cold climates. It can help reduce heating and cooling costs significantly and keep the interiors of a building comfortable.

Environmentally Friendly

This is also an environmentally friendly material. It is 100% recyclable and can be reused for other purposes. Additionally, it has a low carbon footprint, making it an excellent choice for sustainable building projects.


Extruded polystyrene is fire-resistant, making it an excellent choice for buildings that need to meet fire code regulations. It is classified as a Class A material which means it is highly resistant to flame spread and produces low smoke levels.


This material is cost-effective compared to other building materials. Its lightweight properties and easy installation make it a popular choice for builders and architects looking to save on labour and transportation costs.

Moisture Resistance

XPS insulation is moisture resistant, making it an ideal choice for areas that are prone to moisture build-up. Unlike other insulation materials that can easily absorb moisture, XPS insulation does not absorb water, which makes it an excellent choice for basements, below-grade walls, and other areas that are prone to moisture problems.


Extruded polystyrene is a versatile material that has numerous benefits for building projects. Its insulation properties, durability, and environmentally friendly nature make it an excellent choice for both residential and commercial construction. Additionally, its water-resistant, fire-resistant, and lightweight properties make it a versatile material that can be used for a variety of applications. With its affordability and ease of installation, this material is a go-to material for builders and architects looking for high-quality materials that deliver results.
