Moisture Control is the First Step to Mold Control

Water from both exterior and interior sources is among the worst enemies of building structures. When moisture enters and remains within the wall system, it creates a favorable environment for the development of rot, mold and mildew. Repairing these types of problems can be very difficult and extremely costly.

Air Control is the First Step to Better Energy Performance

The key to optimizing energy performance is preventing the movement of air both into and out of the building envelope. Air leaks around window and door openings make it difficult to keep a comfortable indoor environment, forcing the HVAC system to work harder, while driving up energy costs.

A properly integrated flashing tape that adheres and seals aggressively to the substrate will create the most effective barrier against water and air migration while acting as a drainage plane to shed water down the exterior of the building envelope.

What Makes VYCOR® PRO Flashing Different?

VYCOR® PRO flashing, with its unique film and non-asphaltic, butyl-modified adhesive technology, provides premium protection against water infiltration in all critical non-roof detail areas, that traditional building papers, felts, housewraps and other flashing products cannot match.

In addition, VYCOR® PRO’s wide application and service temperature windows make it appropriate for use in any environment.

Product Description

VYCOR® Pro flashing is composed of a durable, tear and puncture resistant engineered polypropylene backing film, paired with an aggressive, non-asphaltic, proprietary butyl-modified adhesive. VYCOR® PRO flashing comes in 75 ft rolls and is available in:

• 4 in. (102 mm)
• 6 in. (150 mm)
• 9 in. (225 mm)
• 12 in. (305 mm)

Features & Uses

• Superior adhesive capabilities — Non-Asphaltic, proprietary butyl-modified adhesive seals and adheres to the substrate creating a best-in-class barrier against air and water intrusion.
• Seals around fasteners — The specially formulated adhesive seals around fasteners, preventing water penetration.
• Forms water-tight laps — VYCOR® PRO’s superior adhesion properties ensure strong overlaps. 
• Highly Conformable — Thin and pliable membrane is easily worked into tight details.
• Wide application window — Primerless adhesion to wood sheathing from 25°F (4° C)
• Wide Service Temperature Window — Suitable for in-service conditions up to 176° F (80° C)
• Long exposure time — 120 days of exposure provides protection over long, unpredictable construction cycles
• Flexible Application — VYCOR® PRO’s wide performance window makes it appropriate for use in all regions
• Easy to work with — This high performance barrier membrane is easy to apply with 6 and 12 inch (150 mm and 305 mm) measurement markings.
• Superior Weather Protection Solution — Use in combination with VYCOR® ENV-S™ or VYCOR ENV® fully-adhered weather barriers to provide superior protection from wind driven rain.

Compatibility

• VYCOR® Pro flashing contains no asphalt, and is fully compatible with rigid and flexible PVC window nailing flanges.
• Compatible with common weather resistive barriers and many types of sealants. Refer to Technical Letter 1, Chemical Compatibility with Other Building Materials and Sealants for more information.

Usage

VYCOR® PRO flashing is a unique solution appropriate for working around a number of detail areas, including, but not limited to:

• Window and door openings (headers, sills, jambs, thresholds, nailing flanges)
• Deck-to-wall intersections
• Corner boards
• Wall-to-wall tie-ins
• Foundation sill plates
• Sheathing panel seams
• Under stucco finishes
• Masonry walls
• Application to EPDM in vertical applications
• Other non-roof detail areas
