Our cork insulation panels combine sustainability and performance. Cork is a sustainable material for sustainable construction and in the form of cork board insulation offers high performance in thermal, acoustic and anti-vibration insulation, especially suitable for use in external and internal walls, slabs and floors, roofs and ceilings. It is a fantastic thermal and insulator and offers acoustic protection. Each cork insulation panel is environmentally friendly and 100% recyclable at the end of it’s lifespan – they are made from a renewable raw material – cork, which is undergoes a thermal process and releases a resin called suberin – which acts as a natural binder, so no substances are required to form the insulation panels and hold them together.
Because of the natural properties of cork, these insulation boards can be particularly well suited to areas where high moisture levels are present, such as bathrooms and basements. We have specific insulation system which utilizes cork boards working in conjunction with lime plaster to give a robust and eco-friendly insulation system – View our cork based wall insulation system here.
ISOVIT PAINEL ICB is used as thermo-acoustic insulation in the ISOVIT CORK (ETICS) external thermal insulation composite system, correcting linear thermal bridges and reducing their thermal transmission, thereby improving the energy efficiency of the building where it is set up, as well as the acoustic comfort of houses by increasing insulation to the outside noise (air sounds).

FAQs
Amorim Cork Insulation Board (ICB) FAQs
What is Amorim Cork Insulation Board (ICB)?
Amorim Cork Insulation Board, often referred to as ICB, is a rigid insulation board made from 100% natural expanded cork granules. The boards are manufactured using heat and pressure, which activates the cork’s natural resins to bind the material together without synthetic adhesives.
What is cork insulation board used for?
Cork insulation boards are commonly used for:
• External wall insulation systems
• Internal wall insulation
• Roof insulation in breathable build-ups
• Floor insulation and ground-bearing slabs
• Timber frame and masonry construction
They are suitable for both renovation and new build projects.
Is cork insulation breathable?
Yes. Expanded cork insulation boards are vapour permeable, allowing moisture to move through the structure. This makes them suitable for breathable wall systems and heritage building applications.
Is cork insulation environmentally friendly?
Yes. Amorim Cork Insulation Board is made from renewable cork harvested from cork oak trees without harming the tree. The manufacturing process uses no added synthetic binders, and cork is recyclable and biodegradable.
How is cork insulation board manufactured?
Cork granules are expanded using superheated steam. During this process, the cork releases a natural resin called suberin, which binds the granules together. No artificial glues or chemical binders are required.
Is cork insulation fire resistant?
Cork insulation has good fire performance characteristics and will char rather than igniting or melting. It does not produce molten droplets like some synthetic insulation materials.
Does cork insulation provide thermal insulation?
Yes. Expanded cork insulation boards offer consistent thermal performance and help reduce heat loss through walls, roofs and floors. They also provide thermal mass benefits, helping regulate indoor temperatures.
Is cork insulation suitable for external wall insulation?
Yes. Cork boards are widely used as part of external wall insulation systems. They can be mechanically fixed and rendered with compatible breathable lime or mineral renders.
Is cork insulation durable?
Yes. Cork is naturally resistant to mould, pests and decay. When installed correctly, cork insulation boards have a long service life and maintain their composition over time.
What are the key benefits of cork insulation compared to synthetic insulation?
Cork insulation offers:
• Natural and renewable material
• Breathability and moisture regulation
• No added chemical binders
• Good acoustic performance
• High durability
• Reduced environmental impact
It is often chosen for sustainable, ecological and heritage construction projects.
