- Soft lead flexes with building movement
- Reduces sealant exposure, extends joint life
- Oxidizes grey to blend seamlessly with masonry
GSA Historic Preservation Specified
U.S. Patent 6991400
WEATHERCAP Joint Caps are patented soft lead strip systems designed to protect masonry joints from moisture penetration caused by building movement. Used in horizontal and vertical masonry applications, they extend sealant life, resist corrosion, and preserve structural integrity on both historic landmarks and new construction.
In masonry construction, a joint cap (like WEATHERCAP) protects the sealant within a masonry joint from environmental exposure and building movement. It reduces the effective joint opening size, buffers stress at right-angle transitions, and prevents moisture penetration that could otherwise damage the sealant and surrounding structure over time.
