DuPont™ Tyvek® StraightFlash™ VF VersaFlange™ – 6 in x 125 ft Self-Adhered Window & Door Flashing

DuPont™ Tyvek® StraightFlash™ VF VersaFlange™ – 6 in x 125 ft

DuPont™ VersaFlange™, formerly known as Tyvek® StraightFlash™ VF, is a professional-grade self-adhered flashing membrane designed specifically for non-flanged and brick mold windows and doors.

It helps connect the window or door frame to the surrounding sheathing or weather-resistant barrier (WRB), helping protect vulnerable openings from bulk water intrusion and supporting a more durable building envelope.

VersaFlange™ is especially useful for openings that do not have a standard integral mounting flange and require a specialized flashing detail.

Best For

• Non-flanged windows and doors
• Brick mold window and door installations
• Connecting frames to sheathing or WRB
• Professional window and door flashing details
• Contractors and builders who need a purpose-built flashing system

Key Benefits

• Designed for non-flanged and brick mold openings: Made specifically for window and door configurations that do not use a standard integral flange.
• Specialized dual-sided butyl adhesive: Helps create the connection between the window or door frame and the surrounding wall system.
• 100% butyl adhesive: Provides durable adhesion without asphalt or bitumen.
• Durable Tyvek® topsheet: Designed to withstand normal jobsite handling and installation conditions.
• Scored release liner: Helps make installation and positioning easier.
• Repositionable initial tack: Allows installers to make adjustments before applying firm final pressure.
• Long UV exposure tolerance: Designed to withstand up to 270 days of UV exposure when installed according to DuPont guidelines.

Typical Applications

• Brick mold windows
• Brick mold doors
• Non-flanged windows
• Non-flanged doors
• Window and door jamb flashing
• Head flashing details
• Straight-run flashing applications
• Integration of window and door frames with sheathing or WRB

How VersaFlange™ Compares

Choosing the correct DuPont™ flashing product depends on the type of opening and installation detail.

• VersaFlange™ / StraightFlash™ VF: Best for non-flanged and brick mold windows and doors. It uses a specialized dual-sided adhesive configuration to integrate the frame with the surrounding sheathing or WRB.
• Tyvek® Flashing Tape: Better suited for standard flanged window and door applications and general straight flashing details.
• Tyvek® FlexWrap™: Better suited for corners, curved surfaces, sills, and transitions that require a flexible flashing membrane.

Installation Notes

• Install only on clean, dry surfaces that are free from frost, dirt, oil, moisture, and loose debris.
• Follow the DuPont™ installation sequence appropriate for the specific window or door configuration.
• Remove the scored release liner only as needed during installation.
• Apply firm pressure across the adhesive contact areas to achieve a strong bond.
• A roller is recommended where appropriate to help ensure proper adhesive contact.
• Reposition the membrane before applying full pressure if alignment needs correction.
• Always maintain proper flashing sequence so water is directed toward the exterior.

Why It Matters

Window and door openings are common locations for water intrusion. A purpose-built flashing membrane helps protect framing, sheathing, insulation, and interior building components by helping direct bulk water away from the opening.

VersaFlange™ is engineered specifically for challenging non-flanged and brick mold installations where a conventional flange flashing method may not be appropriate.

Frequently Asked Questions

Is VersaFlange™ the same as Tyvek® StraightFlash™ VF?
Yes. StraightFlash™ VF is the former product name associated with VersaFlange™. The VersaFlange™ name may be used on newer packaging and product literature.

Is the entire 6-inch width adhesive on both sides?
No. VersaFlange™ uses a specialized dual-sided adhesive configuration for its intended window and door installation method. It should not be interpreted as conventional flashing tape with full-width adhesive coverage on both faces.

Is this full-width double-sided flashing tape?
No. If your project specifically requires adhesive covering the complete width of both sides of the membrane, this product is not designed for that application.

What type of openings is this designed for?
VersaFlange™ is designed primarily for non-flanged and brick mold windows and doors.

Can I use this for curved corners or complex transitions?
For curved surfaces, corners, and transitions that require more flexibility, Tyvek® FlexWrap™ is generally the more appropriate DuPont™ flashing product.

Does this contain asphalt or bitumen?
No. VersaFlange™ uses butyl adhesive rather than asphalt-based adhesive.

Before Ordering

Confirm that your installation calls for VersaFlange™ / StraightFlash™ VF and that the specialized adhesive configuration matches your window or door flashing detail. If you need conventional full-width double-sided adhesive flashing, choose a product specifically manufactured and labeled for that application.
