Casement Window Installation Diagram with Framing Details #23601 (License: Personal Use)

This technical illustration depicts a casement window integrated into a brick exterior wall, featuring precise framing specifications: two 2×10 headers spaced 16 inches on center, a 2×4 sill plate, and a “button” support block. The window is shown open at an angle, revealing the structural relationship between the wood framing, masonry backup, and flashing plane. Annotations emphasize critical load-bearing and moisture management details essential for code-compliant construction.

Used in construction manuals, builder training materials, or HVAC/ fenestration guides to demonstrate proper window rough opening framing in masonry walls; targets architects, carpenters, and home inspectors seeking compliance with building codes like IRC Section R602.
