This architectural drawing is a SEALING DETAIL of the structure in AutoCAD 2D drawing, CAD file, and dwg file. One sort of mechanical seal is a substance called sealant that is used to stop fluids from passing through gaps in materials. Sealants are used to prevent the passage of heat, sound, and dust in building construction and are sometimes interchangeable with caulk. For more details and information download the drawing file.
