Product Description
The UltraSpan™ US1100 Pre-Cured Silicone Weatherstrip is a low-modulus silicone rubber strip designed for new and remedial sealing applications. It delivers a long-lasting, durable, watertight seal as a primary or secondary barrier over moving and non-moving joints. With a unique ridged profile, it reduces sealant squeeze-out and improves installation quality. It is suitable for flashing, roofing, splicing, curtainwalls, and repair of failed sealants.
