1 inch (25 mm) beyond the face of the exterior wall. Flashing & Weeps: Continuous sill flashing with end dams must be installed beneath the brick course. Weep holes are then placed in the mortar joints directly under the sill to allow any trapped moisture to escape. Drip Detail: A drip groove or projection is essential to prevent water from running back along the underside of the sill and into the wall. Modeling in BIM Software Architects and designers often face challenges modeling these details in software. Here are common workflows: Revit: Experts recommend modeling the sill within the window family rather than as a separate wall sweep, allowing it to resize automatically with the window. Chief Architect: Since built-in sill functionality can be limited, many users utilize
The top surface of the sill must be sloped. This is often called a "wash." A flat sill allows water to pool, which leads to saturation and leaks. brick sill detail
A well-designed and installed brick sill detail is essential to prevent water infiltration, damage to the building's structure, and to ensure the longevity of the building. By understanding the components of a brick sill detail and following best practices for design and installation, architects, builders, and homeowners can ensure a watertight and durable exterior envelope. A properly designed brick sill detail is a critical component of a building's exterior envelope, providing a visually appealing finish to the window and door openings while protecting the building from the elements. 1 inch (25 mm) beyond the face of the exterior wall
