Carton of (4) Straight Flash Tyvek

The DuPont™ StraightFlash is a premium, self-adhered flashing designed to provide superior protection for the heads and jambs of rectangular windows. As part of the DuPont™ Weatherization System, StraightFlash bridges the gap between the rough opening and the building envelope, protecting one of the most vulnerable areas of any structure from water infiltration and potential damage.

Engineered with DuPont™ Tyvek® and a 100% butyl-based adhesive, StraightFlash offers exceptional durability and weather resistance. Its versatile design makes it ideal for a range of residential and commercial applications, providing lasting protection while contributing to energy efficiency and sustainability.

Key Features:

• Superior Water Resistance: Effectively protects against water intrusion at the heads and jambs of rectangular windows.
• 100% Butyl-Based Adhesive: Ensures a strong, long-lasting bond that withstands extreme temperatures without compromising performance.
• UV Resistant for 120 Days: Allows extended exposure to sunlight without degradation, providing flexibility during construction.
• Durable & Tear-Resistant: Made from high-quality DuPont Tyvek® for lasting strength and resilience.
• Easy Installation: Features quick-release backing and forgiving initial tack for easy repositioning and accurate placement.
• Cold-Weather Application: Can be applied in temperatures as low as 25°F, maintaining pliability in colder conditions.
• Adheres to Most Common Building Materials: Works with wood, vinyl, metal, and other substrates.
• No Asphalt Content: A cleaner, more environmentally friendly product without the mess of asphalt-based flashings.
• AAMA Approved & Code Compliant: Meets AAMA 711-07 standards for self-adhering flashing and complies with modern building codes.
