Flexible seal, easy installation.
Keep weather out of hard-to-seal areas with US1100 UltraSpan* weatherstrip. This pre-cured, 100% silicone weatherstrip helps create watertight splices, seals, and transitions in new or remedial applications. Its distinctive ridged profile is highly effective and easy to apply.
US1100 UltraSpan weatherstrip remains elastic no matter the weather, and repels dirt to help keep buildings looking beautiful. Its low-modulus formula maintains optimal flexibility while working to minimize stress at transitions and joints. US1100 UltraSpan can deliver exceptional performance to repair and restore failed sealants in joints, skylights, flashing, parapets, window perimeters, and on EIFS.
US1100 UltraSpan weatherstrip is fully compatible with most silicone sealant and coating products by GE Silicones. Used together, they form a highly effective barrier system to seal out water and air.
US1100 UltraSpan weatherstrip is backed by world-class technical support and our extended limited warranty.
