A high-vapor permeable, watertight roofing underlay ensures proper drying of structures and insulation materials.

  • ensures proper drying of the construction and insulation materials
  • enables the formation of a pleasant microclimate in the space
  • due to its features it increases the thermal insulation properties by about 10%
  • extends the lifetime of the construction, substructure and cover
  • the possibility of installing the roof repayment, horns or diagonal concrete slab
  • prevents penetration of the pest and thus protects the structure from decay and rotting
  • prevents cooling and condensation of water in thermal insulation
