    Project Description

    Corotop® ULTRA 220

    An extremly durable, three-layer, highly vapour permeable membrane produced in a thermobonding technology. The product is higly resistant not only to mechanical damages, but also unfavourable weather conditions including UV-rays and high temperatures. This product is recommended especially on fully-boarded roofs and when a construction is exposed to heavy load. The membrane offered to clients who appreciate the best quality.

    Application:

    •  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 and concrete tiles

    Advantages:

    •  minimize heat loss
    • regulate two-way vapour permeability
    • protects thermal-insulation againts damping
    • very high grammature guarantees extreme resistance to any damages
    • also available in version with 2 adhesive stripes (Corotop Ultra 220+)
