Foilboard Insulation

Foilboard Insulation is designed for use in walls, floors and roofs. Foilboard 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. It is suitable for residential, commercial and industrial applications.

Foilboard for Walls, Ceilings and Floors

Unlike traditional bulk insulation and insulated batts, Foilboard® GREEN’s slimline profile makes for an ideal thermal break & vapour barrier, and with its superior thermal performance, it ensures a continuous “eskie” effect to the building year round. Some of the benefits of Foilboard are listed below:

  • Endorsed by Standard Australia
  • BCA Compliant
  • Fire retardant insulation panel
  • Does not require the use of protective clothing or safety gear whilst installing
  • Green insulation – Formaldehyde free
    CFC & HCFC free
  • The insulated panels have Zero Volatile Organic Compounds (VOC’s)
  • Has no harmful carcinogens ( No dangerous fibrous airborne particles
  • Achieves high R-values without the need for reengineering the building’s design
  • An insulated panel can be Installed without gaps
  • Lightweight and fast to install foil insulation board
  • Foilboard insulated panels are Impervious to moisture
  • 100% Australia made
  • 100% Australia owned

The difference between rigid insulation sheets and batts

Foilboard® GREEN rigid board insulation will maintain the same thermal performance (R-value) for the life of the insulation panel. It will not sag and it will not delaminate. Foilboard® Australia backs its Foilboard® GREEN with a 25 year performance guarantee. Fully endorsed by Standards Australia, the Foilboard® GREEN rigid insulation panel is the premium insulation product in its market, both in manufactured quality and product performance and that is why it is backed by a 25 year performance guarantee. This durable rigid panel is specifically designed to achieve exceptionally high thermal values, making it the ideal product. Unlike traditional bulk insulation and blankets, this rigid panel will not shrink, sag or droop, ensuring that the building performs to its optimal thermal value from day one, to year 25 and beyond. The insulation board cost depends largely on its R-value (also known as R-rating) however bulk order discounts are also available.

Reduce Your Energy Costs with Foilboard

Foilboard® GREEN rigid insulation panel ensures optimum performance by creating a thermal barrier around your building or home – reducing your energy consumption costs and carbon footprint making for a healthier, greener environment. The material’s ability to create a more consistent ambient temperature means you are not reliant on inefficient artificial heating and cooling. This reduces energy use and the production of greenhouse gases creating a more sustainable future for all and saves you money. The pure aluminium that is directly laminated to both sides of the Foilboard® Insulation Panel is 100% recyclable.

Foilboard Insulation FAQs

Foilboard insulation can be used in a wide range of commercial and residential applications, and is suitable for ceilings, walls, underfloor and under slab applications. The reflective foil insulation panels can also be used for insulating caravans, garages, sheds and containers. Foilboard insulation is a popular choice for both new builds and retrofit projects and is compliant with the Building Code of Australia. 

Foilboard Green insulation panels are available in a range of R values. Incorporating them in your project will improve the total R value of the building. How much depends on the type of building, installation method, and amount of air space. For example, installing a Foilboard GREEN rigid insulation panel into a standard 150mm concrete precast system can increase the thermal performance from R0.3 to R2.4.
The added R value that Foilboard insulation can offer your project depends on the installation method and the amount of air space adjacent to the panels. A larger air space will lead to higher R values, so long as the air space isn't ventilated or classified as 'open'.

Foil insulation panels are an affordable and effective insulation product, trusted throughout Australia by builders, home owners and designers. The industry-leading product is designed to provide continual thermal performance throughout the lifetime of your building, which makes it great value for your investment. Foilboard Insulation is endorsed by Standards Australia and is backed by a 25 year performance guarantee.

Foilboard Insulation is simple to install and easy to handle. Use the installation guides listed above, or contact our customer service team for advice.
Follow these tips for an effective installation:
  • Install with the anti glare side (the green side) facing outwards. You can install Foilboard GREEN rigid panels horizontally or vertically, however Foilboard recommends using a horizontal pattern to ensure the best possible fixing.
  • Use the gridlines to measure the panels to the correct size. They are easy to cut with a sharp blade or knife. Use any cutoffs to fill in gaps and smaller sections.
  • Start from the top of the building and work downwards. In windy conditions, start on the windward side of the building.
  • Tape the joints between panels to ensure an airtight seal. This prevents any thermal leakage and makes sure you achieve the highest R value or thermal performance possible.

Foilboard Install Guides

Foilboard Insulation is designed for a range of applications including walls, ceilings and underfloor areas. Click on the links below to learn how to install Foilboard Insulation in different applications.

Yes, Foilboard insulation can be used in conjunction with bulk insulation, we recommend using it with bulk insulation, such as Knauf Earthwool Insulation for residencial homes.

Yes, Foilboard can be used as a vapour barrier. The reflective foil insulation panels create a non permeable moisture barrier with zero vapour transmission. Due to the waterproof materials, the boards are impervious to moisture. No air passes through the boards, meaning inside and outside air do not meet or create a dew point, eliminating the risk of condensation.

In most applications, foil insulation requires an air gap of at least 25mm in order to insulate effectively for radiant heat. Installed without an air gap, and the effective R value of the boards will be close to zero. But installed with the correct sized unventilated air gap, Foilboard insulation can dramatically increase the total insulating performance.

Foilboard panels can be painted, but the paint may affect the way the insulation performs. Since the reflective surface is made from aluminium, it requires etch priming before being painted. If you are using paint, it should be a water clean-up.

Foilboard insulation has a number of environmental advantages. The product has no volatile organic compounds (VOCs) and no CFCs are used in the manufacturing process. The entire product can be recycled. Designed to last the lifetime of the building, Foilboard insulation will require replacing less often than other types of insulation. What's more, Foilboard insulation is effective at improving the energy efficiency of the building. Better thermal regulation inside leads to less reliance on energy for heating and cooling, and therefore less greenhouse gas emissions.
