Architectural Chimney Section Drawings With Firebox Sizes Scale 1 20

This AutoCAD DWG file presents detailed chimney prototype construction drawings, including multiple plan views and sectional cuts labeled as Prototype 1, Prototype 3, and related section references. The drawings clearly illustrate chimney geometry, firebox layout, flue alignment, and structural buildup with accurate dimensions shown in meters. Section drawings such as A A and B B highlight wall thickness, internal cavity sizing, base support, and chimney height relationships. Each prototype is drafted with precise measurements, including widths of around 0.85 to 1.75 meters, vertical heights up to approximately 2.65 meters, and detailed offsets for masonry and lining components. These chimney section drawings support technical understanding for residential and architectural applications.
