Expansion Joint Manufacturers Association: Standards & Members

The soft lead cap covers the sealant, shielding it from UV radiation, moisture, and physical damage, which extends its service life. Its flexibility allows it to creep into new configurations as the building moves, preventing the joint from checking or opening up. This ensures a continuous, long-lasting barrier against water penetration.

WEATHERCAP® is ideal for protecting horizontal and vertical masonry joints in a wide range of applications. It is frequently used for historic building preservation and new construction, particularly on stone copings, parapets, cornices, belt courses, window and door lintels, sills, and entrance steps. It provides a reliable, long-term solution.

Yes, WEATHERCAP® is highly effective for new construction projects requiring maximum durability in masonry joints. It provides long-term protection from day one, reducing future maintenance needs. The A-2 Type A cap, for example, is specifically designed for new-construction installation, while other sizes are suitable for both new and restorative work.

Type A is a flat cap designed for joints where masonry units are set in approximately the same plane, such as the top joints of a coping or lintel. Type B is a 90-degree cove cap designed for right-angle joints, such as where a projecting lintel meets a side wall or a window sill meets the supporting masonry.

Yes, the WEATHERCAP® system can be painted to match the surrounding masonry or architectural color scheme. If left unpainted, its lead surface will naturally oxidize to a dead neutral grey color that blends unobtrusively with most stone and masonry, preserving the building's aesthetic while ensuring robust joint protection.

WEATHERCAP® is supplied in standard 6-foot lengths, allowing for easy handling and field cutting to fit specific joint dimensions. Our manufacturing and supply chain are fully operational, and materials are typically shipped within 48 hours of order placement to ensure your project stays on schedule. All sales are final.
