The BKP has set the development of its liner type from the beginning under one maxim: optimal benefit for every user. Thus, an innovative and flexible production process was created, which allows the specification of a large number of individual parameters - for a product that combines the advantages of previously known liners and also offers new qualities. The Berolina liners are seamless, depending on the requirement profile made of glass fiber or polyester sheets or as a sandwich of both materials, are light-curing and have a theoretically endless stretching behavior. This feature is made possible by the patented engineering wall construction.
The fiberglass complexes in the Berolina liner are overlapping and staggered. This realizes decisive advantages.
The Berolina liner can also be laid in a single step for cross-section and / or profile transitions and adapts to the conditions without difficulty.
The continuous fiber orientation in the circumferential direction optimizes the flow of forces without hindering the expansion.
