Automotive & Finished Parts


The careful selection and optimum processing of our fibers ensure that isoGLAS® products by Frenzelit shine with optimized properties.
Our high-temperature-resistant textile glass fibers pave the way for application-specific acoustic and thermal insulation. For many years we have been driving the development of new finishing techniques. 


Application temperature limit 550 °C (short peaks up to 650 °C)

E-glass is the base material. isoGLAS® products are extremely textile and harmless to health. Texturing guarantees a large storage volume and thus good insulation properties.
