TRI-FIN® Weatherseals

Description

• 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 ULTRA SOFT FIN®. Ultrafab can also provide a combination of ULTRA SOFT FIN® and ULTRA FIN®
