Vycor® Plus

Vycor® Plus, a high performance self-adhered flashing membrane, provides premium protection against water infiltration in all critical non-roof detail areas, that traditional building papers, felts and housewraps cannot match. When properly installed, it can reduce the risk of rot and mold development, often associated with costly call-backs.


  • Ripcord — With the sophistication of construction practices it becomes a must to follow the proper sequencing principles. Ripcord offers the flexibility to install half the membrane before and the other half after the other building envelope components are installed, i.e. housewrap or felt. Only in this way are the proper installation principles followed.
  • Easy to work with — Membrane installation is fast and easy—simply remove the release paper and press onto the substrate. With Vycor Plus contractors can flash more windows with better quality.
  • Superior adhesion capabilities — The membrane creates a strong bond to the substrate for long-lasting waterproofing protection.
  • Seals around fasteners — The specially formulated rubberized asphalt adhesive seals around fasteners, allowing no water to penetrate and get to the substrate.
  • Forms water - tight laps — Vycor Plus’ superior adhesion properties ensure strong laps, even in seams in the flashing.
  • Measurement markings — The membrane surface is clearly marked at every 6 in.(150 mm) and 12 in. (300 mm) intervals to facilitate the installation procedure.
  • Highly conformable and flexible — Can accommodate settlement and shrinkage movement.
  • Proven track record — Vycor Plus employs the same proven technology as our Ice &Water Shield®—the market leader in self-adhered underlayments for over 30 years.
  • Long-lasting waterproofing protection — Both the polyethylene film and the specially-formulated rubberized asphalt components create a water and moisture barrier that does not degrade from the effects of the environment.
