SureSpan EX | Flexible Silicone Transition for Air Barriers
SureSpan EX is a high-performance, pre-cured silicone bridging system designed to create continuous, flexible transitions between air and water barriers and structural components such as windows, curtainwalls, or storefronts. It spans irregular geometries, seals dynamic joints, and absorbs movement and loading stress without requiring mechanical fasteners.
Product Description
Supplied in translucent yellow cured silicone, SureSpan EX simplifies quality inspection and delivers a durable seal that accommodates building movement. This elastomeric material is compatible with most sealants and glazing materials and is easy to install in both new construction and retrofit applications. It effectively bridges gaps that are too wide or complex for traditional joint fillers or flashings, delivering reliable protection for demanding building envelope conditions.
Key Benefits
- Seals complex or wide transitions between dissimilar building materials
- Ideal for high-movement joints, skylights, curtainwalls, and flashing
- Requires no mechanical fasteners—easy to apply
- Maintains continuous air and water barrier integrity
- Compatible with most sealants and R-Guard products
Common Applications
- Window-to-wall transitions
- Skylight or curtainwall flashing systems
- Dynamic joints subject to thermal and structural movement
