摘要

The cover material (10) in the form of a thermoplastic sheet (18) with sticky surfaces is provided at least on its top surface with a cover layer (22) which consists essentially of a durably weather resistant plastic material with a non-sticky surface. This layer covers at least 80 % of the width of the thermoplastic sheet.
