Windows provide light, ventilation, and architectural character. This episode covers window types, construction, installation, safety requirements, and energy efficiency considerations.

Window types explored include:
- Fixed windows (transoms, fanlights, eyebrows, sidelights, Palladian)
- Operable windows (double-hung, single-hung, sliding, casement, hopper, awning)
- Bay and bow windows
- Special considerations for each type

We detail window components: sashes, frames, glazing, rails, stiles, meeting rails, muntins, jambs, sills, tracks, and trim. Understanding these parts is essential for identifying defects and communicating findings.

Installation standards cover proper rough opening preparation, flashing integration (a common failure point), attachment methods, and the importance of square and plumb installation.

Safety requirements receive extensive coverage:
- Emergency escape and rescue openings (5.7 sq ft minimum, specific dimensions)
- Window wells for below-grade openings
- Fall protection for operable windows near floors
- Safety glazing requirements (in doors, near doors, near bathing areas, large windows, near stairs)

Energy efficiency topics include Low-E coatings, hermetic seal integrity, and the limitations of home inspection regarding energy performance assessment. Typical defects and IRC 2018 R308 and R310 standards round out this comprehensive episode.
