    Project Description

    Corotop® Active Control 98

    Two-layer vapour insulation based on polypropylene fibre. The product is actively vapour-permeable and can be applied on roofs, walls and floors as the vapour-permeability regulator. Thanks to modern technology it creates an active water vapour-barrier and eliminates the „plastic bag” effect, which can be a reason for mildew arise.


    • to attics, walls and ceilings
    • recommended in rooms where increased vapour level is generated
    • applied as a complementary product with high vapour permeable membrane in a roof system


    • light and easy application
    • protects thermal insulation againts damaging water and damp influence
    • prevents from mildew arise
    • helps to sustain healthy and fresh climate at the attic
    • actively regulates vapour level in a room
