Being labour intensive would mean a higher investment for the buyer. However, your energy bill will immediately drop. Making cork a sustainable material as well as it a competitive energy-efficient and eco-friendly insulating material.


Cork has a high specific heat capacity and high thermal inertia. Keeping homes warm in the winter, and cool in the summer.


Cork’s unique structure enable it to absorb up to 70% of tones that are found within the 400 to 4000Hz frequency range. Instead of transmitting sound waves and vibrations, cork absorbs them. Thus possessing anti-vibration properties, which is advisable for a house in large noisy cities and areas.


Being naturally resistant to moisture, cork will not need a specific moisture barrier to strengthen resistance.
