Every style earns its place somewhere in the house. Here is the plain-English version - what each one is, where it belongs, and the detail most people never hear.
Casement windows
WhatThe one that cranks open outward like a door.
WhereOver kitchen sinks and anywhere you want the full opening for air.
Fun factThe open sash catches side breezes that sliding windows miss entirely.
Double-hung windows
WhatTwo sashes that slide up and down independently.
WhereBedrooms and traditional facades - the classic American window.
Fun factBoth sashes tilt inward, so you wash the outside glass from inside the house.
Bay & bow windows
WhatThree or more windows angled out from the wall.
WhereLiving and dining rooms that want light from three directions.
Fun factAdds a window seat’s worth of usable space without moving a wall.
Sliding windows
WhatA sash that glides side to side on a track.
WhereWide openings and rooms facing patios or walkways.
Fun factNothing swings outward, so it never blocks a path or a porch.
Picture windows
WhatFixed glass that does not open at all.
WhereFraming a view you never want interrupted.
Fun factThe most airtight window made - nothing moves, so there is nothing to seal.
Awning windows
WhatHinged at the top, opening from the bottom.
WherePlaced higher on walls for privacy with airflow.
Fun factSheds light rain while open - fresh air even in a drizzle.

Six Reasons San Diego Homeowners Upgrade Their Windows
Laminated glass and reinforced frames hold up to wind-driven rain, hail and flying debris, so your openings stay sealed when the weather turns.
Low-E insulated impact glass from our manufacturer lines commonly cuts monthly cooling bills 20-30%.
Laminated impact glass shuts out up to 40% of outside noise - traffic, neighbors, weather.
Monitoring services run $30-90 a month. Laminated impact glass resists forced entry around the clock, with no subscription.
