What a picture window is
A picture window doesn't open. With no sash or meeting rail, it gives you the largest uninterrupted glass and the best seal of any window. Many homeowners flank one with casements or sliders on each side for air.
Glass for big windows
A large pane facing west or south collects a lot of heat. Low-E coatings tuned to block solar heat matter more on a big window than anywhere else in the house. Tempered glass is required in some locations, such as near doors and floors. See low-E glass for New Mexico.

Frame choice
Bigger glass is heavier. Fiberglass and wood-clad frames stay stiff in large sizes and allow narrower frames. Vinyl works well for many picture windows too; size limits vary by brand.
Installation
Big units take a bigger crew and careful handling. We plan access, protect floors and furniture and set the window square and level so it seals properly.

Common questions
Can you enlarge my window opening?
Sometimes. Making an opening bigger involves the wall structure and stucco and often needs a permit. We'll tell you what's involved.
Will a big window make the room hot?
Not with the right glass. Solar-control low-E makes a big difference on west and south walls.
