Tri-Fin® Weatherseals

ULTRAFAB'S ultimate pile weatherseal for minimizing air and water infiltration

• Three pliable barrier fins integrated into an assembly with self-supporting pile, and built-in "pile directors", providing the ultimate seal in a pile and fin weatherseal
• Tests have indicated a 25% improvement in air infiltration compared to a single fin
• Solid polypropylene backing inserts more easily, saving time and reducing waste
• Pile height and backing width are always uniform because of ULTRAFAB's unique non-woven manufacturing systems
• Tri-Fin® weatherseals have the structural integrity and consistency which assures a tight seal and barrier against air and water infiltration
• No possibility of off-center pile that binds, breaks or stretches in an extrusion
• ULTRAFAB's unique ultrasonic welding assembles the fin, fibers and backing into an integrated, unified assembly that won't break apart during fabrication or while in use
• Need a softer fin? Ask about Soft Touch Fin®. ULTRAFAB can also provide a combinaton of Soft Touch Fin® and Ultra Fin®

Tri-Fin® Weatherseal Choices
