Instruction for Use

Preparation of the substrate:
The surface of the base substrate shall be strong, even, smooth, clean, dry and free of foreign bodies.
  • Two-layer membrane underlay film, non-adhered system with heavy-duty protection. The membrane is laid loosely on the substrate or with the addition of a geotextile separating layer (optional). The longitudinal overlaps are 8 cm, and are welded by removing the protective films and pressing to achieve self-adhesion. The transverse overlaps are 20 cm, of which 10 cm are welded and the rest serves as protection.
  • Two-layer non-adhered system membrane underlay for green roofs. The sheet is laid loosely on the substrate or with the addition of a geotextile separating layer (optional). The longitudinal overlaps are 8 cm, and are welded by removing the protective films and pressing to achieve self-adhesion. The transversal overlaps are 20 cm, of which 10 cm are welded and the rest serves as protection.
