Our expanded insulation cork products (dark brown lower-density cork) may have a noticeable smell upon receipt. The smell is often described as a smoky or burnt wood scent, similar to wood heated over a campfire. It is the result of the natural production process, where cork granules are exposed to heat and pressure, releasing a natural binder that eliminates the need for toxic synthetic adhesives. This process essentially "bakes" the cork granules, producing the characteristic scent.

The strength of the odor depends on factors such as the size of the space and the level of ventilation. It gradually becomes less intense over a period of time, with the rate of dissipation being highly dependent on airflow. Installing in a well-ventilated space and leaving windows open during and after installation will help the scent dissipate more quickly.

If you are sensitive to the smell or wish to reduce it more quickly, applying a sealer such as a water-based polyurethane or polycrylic will help seal in the odor. It is a good idea to choose a product with UV protection for added long-term benefit.
