Manufactured using processes that do not produce ozone-depleting gasses, polystyrene XPS insulation creates a stable and comfortable living environment by reducing reliance on heating and cooling appliances, saving on energy costs and prolonging the life of a building.Manufactured in Australia from high-quality extruded polystyrene, StyroTherm is a highly compressive and durable product. The density and closed cell structure of XPS foam make the product practically impervious to water, dimensionally stable and organically inert.

Fully compliant with the Building Code of Australia, StyroTherm can be used as an insulation material across a range of residential, commercial and industrial buildings. It is particularly effective for floor insulation, under slab insulation, and slab edge insulation, where it reduces thermal bridges.

Extruded polystyrene is also an ideal foam board for model-making and creating event props because it is easy to cut with a knife or wire cutter and can be carved and sanded.

Due to its density, XPS insulation is suitable for use in moist environments with no loss in thermal resistance, and will retain its dimensional stability. It is also easy to install in any weather.

FAQs

What are the benefits of a green roof?

Green roofs provide substantial environmental and economic benefits by improving building insulation, which reduces heating and cooling costs. They also enhance urban air quality by filtering pollutants and particulate matter and extend the life of roof membranes by protecting them from UV rays and physical damage. Green roof systems support urban biodiversity by creating habitats for animals and insects and can increase property value and appeal.

Green roofs on buildings provide recreational spaces that promote mental well-being and stress reduction. They help combat the urban heat island effect, leading to more comfortable living

How do green roofs work?

Green roof systems are multi-layered and combine vegetation with roofing materials. It begins with a waterproof membrane to protect the building from water infiltration. Above this, a root barrier prevents root penetration into the waterproof layer, followed by a drainage layer, which ensures proper water management, and a growing medium supports plant life while retaining moisture. Polystyrene XPS insulation is integrated into the system to provide excellent thermal resistance, further improving the building's energy efficiency by reducing heat transfer.

Incorporating XPS polystyrene insulation into a green roof benefits from improved thermal performance and contributes to sustainability by reducing energy consumption and supporting urban biodiversity.

What is the best green roof material?

The best green roof insulation material provides excellent thermal performance, moisture resistance, and durability. XPS foam board meets these criteria well. It offers superior thermal resistance, which helps maintain consistent indoor temperatures and reduces energy consumption for heating and cooling. The moisture resistance of XPS thermal insulation makes it suitable for green roof applications, where exposure to water and varying weather conditions is expected.

What is the life expectancy of a green roof?

When appropriately installed and maintained, green roof systems in Australia have demonstrated impressive longevity, often lasting between 30 to 50 years or more. With diligent maintenance practices, such as consistent watering, proper drainage management, and periodic inspections to address any potential issues, green roofs can remain durable and functional for several decades, providing long-term environmental and financial benefits.
