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
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.
Does installing Foilboard Green in my house create condensation?
No, Foilboard does not create condensation when installed. As the Foilboard is of a waterproof nature, the passing of air from one side to the other does not happen, thus the inside and outside air of two different temperatures cannot mix to create a dew point. Having no dew point the condensation is not able to be formed.
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
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.
What is foilboard?
Foilboard® is a rigid insulation panel that is installed within existing cavities to ensure the building stays cooler in summer and warmer in winter made by applying pure aluminum to both sides of an FR-EPS Core. One side is coated with a specially formulated ink to create an anti-glare finish that does not inhibit the reflective performance of Foilboard®
