Optima Vario

Winflex® Optima es - The complete window sealing system

Winflex Optima es is the ideal product to seal abutment joints between brickwork and windows - economically and efficiently. The specially developed BOSIG High-Tack adhesive applied full-surface will absorb moisture without loss of adhesion to the substrate. The absorbed moisture will diffuse through the carrier membrane to be expelled from the joint.




  • High elasticity and flexibly adaptable
  • Extremely generous adhesive coating
  • Split cover foil
  • Very good to plaster/paint over
  • No fluid adhesive systems sticking to window surfaces
  • Tight against driving rain up to 600 Pa (outside)
