Abstract (en)

The membrane has a body, and a set of surfaces that is located on both sides of the body of the membrane. One of the set of surfaces includes cork particles having a granulometry ranging between 0.5 to 3 mm, i.e. preferably between 1 to 3 mm. The cork particles are heat treated with steam. A reinforcement (1) is impregnated with mineral or plant bitumen, where the membrane with the cork particles is subjected to double calendaring on a surface by utilizing a set of calendaring units (4, 5). An independent claim is also included for a method for manufacturing a protective membrane.
