Winflex® Vario

Winflex® Vario


Winflex® Vario is a special membrane for quick and safe sealing of installation joints on windows and exterior doors in accordance with recommendations of the guidelines of the German RAL quality assurance association for windows and doors and DIN 4108-7.

With Winflex® Vario the installation joint, depending on weather conditions, can dry out towards the inside or outside, since the water vapour diffusion behaviour of Winflex® Vario flexibly adapts to the physical and structural properties of the building structure, thus helping the installation joints to dry out optimally.

Customer benefits

  • reliable planning, reducing warehousing by half
  • numerous types for every situation of application
  • installation joint dries out optimally
  • structural movements can be absorbed through lateral stretchability / flexibility
