Foilboard

What is Foilboard?

It’s the rigid insulation panel for under your floors, in your walls, in your roof and even to line your man-caves & sheds.

Manufactured in Australia from a fire retardant expanded polystyrene core (FR-EPS) with pure aluminium foil directly laminated to both sides, creating a SUPERIOR INSULANT, THERMAL BREAK and NON-PERMEABLE MOISTURE BARRIER.

Foilboard GREEN has been engineered and designed to ensure a quick and easy installation of a non-itchy, fibre free rigid insulation panel that will provide continuous thermal performance for the life of the building.

How Does Foil Insulation Work?

Foil Insulation works by using the basic laws of heat and cold to its advantage in order to insulate a building. Once installed, reflective foil insulation panels create a barrier between the inside of a property and the external environment. In the case of a hot day, foil insulation panels will reflect heat back out and away from a building, preventing it from getting too hot.

What is R-values achieved for Foilboard?

Total R value is the total of each and every element that makes up the construction of a building, and includes wall/ceiling/underfloor applications such as brick, plaster, internal air, cement sheeting and so on.

Added R value is what the Foilboard Insulation Panel combined with the adjacent still reflective airspaces adds to a particular system. The actual amount of airspace adjacent to the material will have a profound impact on the R value – the larger the space, the higher the R value. If the airspaces are ventilated or classified as open the R values will not be very high at all.

Can Foilboard Green panel be installed in conjunction with Bulk Insulation?

Yes. Although the Foilboard Green panel is designed to replace the need for bulk insulation, you can combine the two if your design and energy rating requirements call for it. For technical advice on how to best achieve this, please contact the Foilboard technical department.

Why is one side green & the other silver?

The Foilboard Green panel is designed as a pure aluminum faced product, one side is coated in a green anti-glare layer for use in applications where the sun may create a glare issue on the construction site. The Antiglare green does not affect the performance of the product.

Tips for cutting Foilboard?

• Always use a sharp knife. This will ensure that the edges are clean and precise.
• Always use a backing material to avoid cutting into the floor.
• Use a steep angle when cutting the board to reduce damage to the styrene underneath.
• Always measure twice and cut once. It’s better to cut a little extra than cut too short.

How does Foilboard Green compare to traditional wrap & batts?

Foilboard Green Insulation Panel eliminates the need for the supply and installation of two separate products at different stages of construction. It also speeds up the construction process by getting you up to lock up stage much sooner.

The most important benefit of the Foilboard Green range is that it provides a true thermal break around a building whilst also giving equal and greater R Values compared with labor intensive batts & wrap.

Where can Foilboard be used?

Foilboard can be used almost anywhere from walls, floors or ceilings within any residential and commercial project, it is even widely used to insulate sheds and factories. There are endless possibilities to where foilboard can be used to insulate.

How does it work?

Foilboard uses its aluminum surfaces to reflect both heat & cold energy sources. This means that in summer the heat on the outer side of Foilboard is reflected off the building, whilst also reflecting the cooler energy back inside. In winter the cold is reflected off the external side whilst the heat is reflected back into the room. Foilboard is able to achieve this by creating a thermal-break with low thermal conductivity – it slows / stops the transfer of heat or cold, preventing the flow of energy (hot or cold) between the two different sides of the panel. The system is also aided by using the still (unventilated) air spaces adjacent to the Foilboard surfaces, transforming the naturally still air next to Foilboard into a reflective air space. This dramatically increases the R-value of the air gap.
