Antique Chimney Caps for Sale: Unique Designs & Styles

Type A is a flat cap designed for joints between masonry units on the same plane, such as copings, balustrades, and lintel tops. Type B is a 90-degree cove cap used where masonry units meet at a right angle, like where a projecting lintel or water table joins a wall. The choice depends entirely on the joint's geometry.

The primary benefit is extending the life of masonry sealant by protecting it from UV rays, weather, and physical stress. Its soft lead composition allows it to flex and creep with building movement, preventing joint checking and moisture penetration. It also resists corrosion and mold and can be painted to match the masonry.

Yes, absolutely. While it is renowned for its use in historic preservation, WEATHERCAP® is also specified for new construction to ensure long-term joint durability. The A-2 Type A cap, for example, is designated specifically for new installations, providing proactive protection for masonry joints from day one.

WEATHERCAP® products are made from a soft lead composition. This material is specifically chosen for its unique properties: it has a low elastic modulus and creeps under stress, allowing it to move and deform with the building's natural settlement and thermal cycles without failing. This ensures a permanent, flexible seal.

WEATHERCAP® is installed as an adjunct to caulk or sealant. The cap's splined anchor shaft is embedded into a sealant-filled masonry joint. This integrated system ensures the cap is held securely while protecting the sealant beneath it. We provide detailed technical information, CAD drawings, and installation guidance to support proper application.

Yes, WEATHERCAP® can be painted to match the surrounding masonry or architectural details for aesthetic purposes. If left unpainted, its surface naturally oxidizes to a dead neutral grey color, which blends seamlessly with most stone and masonry, making it visually unobtrusive while providing superior protection.
