Material Guide: Cork

What is cork and what makes it good?

Cork is a completely natural material that is produced by harvesting the bark of the Cork Oak Tree (Quercus Suber). It possesses many key properties that make it desirable for use as a building material. Among other factors:

• It has insulative properties

• It is sustainable

• It is impermeable (water resistant)

• Its elasticity make it comfortable to the touch

• It is durable

What makes Cork sustainable?

• It can be harvested from the same tree every 9 years without damaging the tree.

• It can be recycled straight back into new cork products

• It’s biodegradable

But keep in mind: Cork Oak Trees are native to Europe and South America meaning that cork is typically imported into Australia and therefore carries that embodied carbon with it.

What is embodied energy?

Embodied energy is the sum of all the energy that is used to produce a material, product or building. This includes the energy required to harvest, manufacture and transport an item. A lower embodied energy is desirable and can be a useful factor in selecting materials.

Where can I use it?

The most common use of cork in the home is for flooring. This is because it has great durability as well as being water and fire resistant. It can also be used in other creative ways to bring warm timber tones into spaces at a lower price.

So should I use it?

Definitely. The cork feels good underfoot, provides insulative qualities and performs well from an environmental perspective. It works well in a warm natural colour palette and can be a stand out feature in your home.

Just make sure you weigh up where the cork is coming from and any other materials, oils or adhesives being added into the cork product you choose.
