IPEX Expansion Joints for Thermal Expansion Management

Lead's unique properties, like its softness and low elastic modulus, allow it to remain flexible and 'creep' into new configurations as a building moves. This accommodates stress without tearing, ensuring a continuous, weatherproof seal that other materials cannot provide, which significantly prolongs the joint's integrity and performance.

Type A is a flat cap for joints between masonry units on the same plane, like on top of copings or across lintels. Type B is a 90° cove cap used for right-angle joints, such as where a horizontal surface meets a vertical wall, around window frames, on entrance steps, or at other perpendicular junctions.

Yes, absolutely. While renowned for historic preservation, WEATHERCAP® is highly effective for new construction, ensuring long-term joint durability from day one. The A-2 Type A model is specifically designated for new-construction installation, providing proactive protection against future movement, settlement, and moisture intrusion in modern masonry.

WEATHERCAP® physically covers the sealant, shielding it from UV radiation, weather, and physical damage. It also reduces the effective size of the joint opening, lessening strain on the sealant during building movement. This protective barrier dramatically extends the sealant's functional lifespan and prevents premature failure and margin checking.

Yes, it is the premier choice for such projects. Its use is specified in the U.S. General Services Administration's (GSA) Historic Preservation Technical Procedures. The system has a proven track record on numerous national landmarks, preserving original masonry while providing durable, long-lasting joint protection that respects historical building materials.

All WEATHERCAP® stock and custom joint caps are supplied in standard 6-foot lengths. This allows for easy handling and transportation to the job site and enables installers to cut the material to the precise size needed for various masonry joint configurations, minimizing waste and ensuring a proper fit for each application.
