Exterior Windows and Doors

Exterior windows and doors are openings and assemblies that connect a building's interior with outdoor light, access, and air. Frames, glazing, panels, hardware, and seals combine to form operating or fixed elements within the exterior enclosure. Placement, proportion, and junction details connect the appearance of a facade with daylight, circulation, and the weather conditions surrounding occupied rooms.
