Winflex® Optima Vario is a special membrane for fast and reliable sealing of abutment joints on windows and exterior doors in accordance with the recommendations of the RAL Quality Assurance Association installation guidelines for windows and front doors and DIN 4108-7.
Winflex® Optima Vario allows the abutment joint to dry out from the inside or outside, depending on weather conditions, since the Winflex® Optima Vario water vapour diffusion characteristics allow it to adapt to the physical properties of the building structure, thus assisting optimal drying of the abutment joints.
The same Winflex® Optima Vario tape can be used for internal and external sealing, in both cases blocking moisture from penetrating the joint.
