Foilboard insulation sheets are Australian made insulation products designed for the demands of the Australian climate. Easy to handle and simple to install, Foilboard insulation sheets are suited to a wide range of residential projects, including new homes, extensions, and detached structures such as sheds, garages, and pool houses.

Each sheet features a polystyrene core with pure aluminium foil laminated to both sides. This construction helps reflect heat away from the building element it is installed to, supporting strong thermal performance across a range of applications. With multiple thicknesses available, Foilboard insulation sheets can be selected to suit different parts of a build, including tighter spaces as well as floor and roof applications.

Foilboard sheets are lightweight, fibre free, and non itchy, making them a practical option where straightforward installation matters. The rigid construction of Foilboard insulation sheets is also designed for long-term performance, making them a dependable choice for projects where ongoing insulation value is important.

Common Uses For Foilboard Sheets

• Insulating under timber floors in new and existing homes
• Use as an all in one moisture barrier, insulator, and thermal break for new homes
• Insulating against masonry and concrete pre-cast walls
• Insulating underneath concrete soffits

Frequently Asked Questions about Foilboard Insulation Sheets

What Is Foilboard?

Foilboard is a rigid insulation panel designed for use within the building envelope. According to the manufacturer, Foilboard GREEN is made by laminating pure aluminium to both sides of a fire-retardant expanded polystyrene (FR-EPS) core, with one side finished in a green anti-glare coating. Its function is to help buildings stay cooler in summer and warmer in winter by reducing heat transfer through the building structure.

What Is Foilboard Used For?

Foilboard is used in a range of insulation applications across walls, floors, roofs, and ceilings. Common uses include underfloor insulation, wall systems, suspended slabs, roof and ceiling applications, sheds, garages, garage doors, caravans, and motorhomes, with the panels usable in both residential and commercial projects.

Is Foilboard Insulation Good?

Foilboard can be considered a strong insulation option when it suits the application and is installed correctly. The manufacturer states that it combines a rigid FR-EPS core with reflective aluminium surfaces, and that adjacent reflective airspaces can improve overall system thermal resistance. Foilboard also describes the product as moisture-resistant, fibre-free, non-itchy, and engineered to maintain its integrity for the life of the building.

What Are the Advantages of Foilboard?

The main advantages Foilboard identifies are that it is lightweight, rigid, fibre-free, moisture-resistant, and easy to install. The manufacturer also says it provides a thermal break, helps reflect radiant heat, is available in multiple thicknesses and sheet sizes, and can be used across a wide range of building elements including walls, floors, roofs, sheds, and garages.
