Features and Benefits

• Smooth Film Surface with Repositionable Adhesive: The special adhesive allows one-time repositioning during installation while maintaining aggressive, long-term adhesion for a flawless fit.
• Self-Sealing Around Fasteners: Self-seals around nails and metal roofing fasteners to prevent water penetration at vulnerable connection points.
• Split-Back Release Film: Peels off in layers for faster, easier installation that reduces labor time and increases homeowner value.
• Fiberglass Reinforcement: Resists wrinkling and buckling to lay flatter under shingles and maintain integrity over time.
• Extreme Temperature Performance: High-temperature compound prevents melting or flowing on metal roofs; passes low-temperature flexibility tests down to −20°F for cold-climate installations.
• Enhanced Footing Pattern: Unique film surface pattern improves footing even in hot weather conditions, reducing slipping hazards during installation.
