Window space
(0% ventilating) a window or area of a window which does not open
Fixed window
(100% ventilating) a window consisting of a number of top-hinged horizontal sashes one above the other, the bottom edges of which swing outward and operated by one control device
Casement window
(50% ventilating) a window which moves horizontally in grooves or between runners
Sliding window
(50% ventilating) a window having two vertical sliding sashes, each closing a different part of the window
Double hung window

Pivoted window
relatively low in cost, lightweight, and corrosion resistant but because they are such efficient conductors of heat, synthetic rubber or plastic thermal breaks are required to interrupt the flow of heat from the warm to the cool side of the frame
Aluminum windows
3 Type of aluminum finishes
- Anodized
- Baked enamel
- Flouropolymer resin
stronger than aluminum, these sections are more rigid and thinner in profile than aluminum sections, offer narrower sight-lines and allow larger lights to be installed in a given rough or masonry opening, the frame and sash sections are welded together and are usually galvanized and bonderized and primed for painting
Steel window
thicker than aluminum or steel frames but they are more effective as thermal insulators, the frames are usually kiln-dried, clear, straight-grained wood, factory treated with water repellant preservative
