    Manufacture of the material with other physical and mechanical properties is accepted upon agreeing about with a consumer.

  • Typical application:

    EXTROOF roofing fabrics are used for reinforcement of roofing materials and other similar purposes.

  •  

    • durability,
    • stable dimensions during processing and service (the fabric is woven plain with leno selvage),
    • stiffness – for maintaining shape of finished material during transportation and storage (the fabric is impregnated with a stiffness-imparting blend),
    • bio and moisture resistance,
    • good impregnability and adhesion with bituminen binding agent,
    • blind (filled up) structure,
    • glass fabric is not inflammable.
