We use ECR Ultrapipe glass exclusively, which was developed together with our supplier specifically for the production of the BB2.5. The material thickness of the glass fibre composite is 0.7 mm. This effects an efficient application of the material, because the deviation to the statically necessary wall thickness lies at 0.6 mm maximum. Cost advantages for the project calculation are the result.
Our glass fibre, which is sewn onto the entire surface of each individual glass roll, forms a homogeneous surface in the pipe liner, which improves the flow properties in the sewer and ensures the durability against wear as well as cleaning in the sewer.
