    Corotop® RED STRONG 180

    Corotop Red Strong is a very durable, three-layer and highly vapour permeable membrane produced by thermobonding method which guarantees strong connection between layers. Using this membrane increases the safety during application and supports moves on a roof slope. It is recommended especially on fully-boarded roofs because of very good resistance parameters. Produced in an unique red colour, being the colour of the Corotop brand, the membrane is a synonime of prestige and the highest quality and bestseller in our offer.


    • the membrane dedicated on roofs with full or part-boarding
    • initial underlay for thermally insulated, ventilated, sloping roofs
    • to be used to most types of roof coverage, particularly under ceramic, concrete and metal tiles


    •  minimizes heat loss
    • regulates two-way vapour permeability
    • protects thermal-insulation againts damping
    • the product with unquestionable resitance parameters in its class
    • the flagship Corotop product
    • also available in version with 2 adhesive stripes (Corotop Red Strong 180+)
