    Project Description

    Corotop® Metallic

    The vapour barrier which is a combination of nonwoven polypropylene with a layer of aluminum screen. Thanks to the reflective coating reflects heat radiation and increases energy efficiency of rooms. Product resistant to mechanical damage.


    • 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
