The process of making Expanded Cork brings to mind... popcorn!

The process of making Expanded Cork Insulation begins with carefully harvesting the cork bark from cork oak trees. The harvested cork bark is sorted and cleaned to remove any impurities such as dirt and debris. The cork is then boiled to soften it and make it easier to work with. The softened cork is cut into small cubes or granules, which are then heated to a high temperature. This causes the cork to expand (just like popcorn), darken and become lighter in weight. Suberin that is released during the process is a natural adhesive that binds the expanding grains. Once the cork is expanded, it is graded based on its size, quality, and colour.
