Expanded polystyrene (EPS) insulation is growing in popularity amongst builders and homeowners seeking energy-efficient building solutions. With rising energy costs and a need to reduce our carbon footprint, EPS provides a cutting-edge way to improve thermal performance dramatically. Continue reading to learn more about what EPS is and what makes it a cutting-edge energy-saving solution.

What is Expanded Polystyrene Insulation?

EPS insulation consists of small plastic foam beads that are moulded into rigid foam insulation panels. The beads are expanded using steam and pressure to form a durable, lightweight and resilient product. EPS contains approximately 98% air, giving it excellent insulation properties. It is available in a range of compressive strength ratings to suit different applications. Common types are standard EPS for insulation behind brick veneer walls and high-density EPS for use under concrete slabs or as structural insulated panels (SIPs). Being mould, moisture and rot-proof, EPS retains its insulation value for the lifetime of the building.

Benefits of Using EPS in Building Construction

EPS insulation provides numerous benefits when used in walls, floors and roofing. It offers excellent thermal efficiency with an R-value of 4 per inch, which helps reduce heating and cooling costs. EPS insulation also improves home comfort by minimising temperature fluctuations and keeping interiors at stable temperatures. Its high insulation values mean thinner EPS constructions can achieve the required R-ratings. The closed-cell structure of EPS resists moisture absorption, making it resistant to mould and mildew.

EPS is lightweight compared to other insulations, reducing construction time and costs of masonry builds, as it is easy to cut, shape and install. It is also a durable material that does not degrade or compress over time, with a lifetime of over 50 years. Finally, EPS is an environmentally friendly insulation containing no CFCs, HCFCs or other damaging gases, and it is completely recyclable.

What makes EPS a cutting-edge energy-saving solution?

EPS insulation dominates in Europe and North America as a high-performance building material. Increased adoption locally in Melbourne and Regional Victoria has seen innovative building techniques emerge that maximise the energy efficiency benefits of EPS:

•  Insulated concrete formwork – Stackable EPS forms create insulated moulds for poured concrete walls. Replaces traditional brick with an energy-efficient concrete and EPS foam sandwich panel.

•  Insulated panel systems – Rigid panels of EPS bonded to oriented strand board (OSB) act as insulated structural walls and roofs. Quick installation and outstanding thermal resistance.

•  Insulated plastering substrates – Direct-fix plastering over EPS creates thin, thermally efficient render facades. Traditional bricks are redundant.

•  Under-slab insulation – EPS geofoam placed under concrete slabs prevents heat loss into the ground.

EPS insulation delivers an affordable, lightweight and environmentally friendly solution to developing thermally efficient building envelopes. As energy prices continue rising, EPS presents an innovative way to minimise heat flow and reduce energy consumption.
