Window & Door Terms - C

Casing
Interior trim installed around windows and doors. Most common types (profiles) are Colonial, Modern and Ranch. Most common widths are 2 1/4" and 3 1/2".
Casement
Window made with one sash which opens (operates) similar to a door on a hinged/track mechanism. Sash is hinged on the top and
bottom. Fixed casements do not have hardware for operation.
Ceiling Joist
Rough-in frame work. 2 X 8s placed above the top plate of the first floor wall frame. Ceiling joists support the ceiling (dry wall, etc.).
Channel Balance
U-shaped metal mechanism with a series of internal ropes, springs and pulleys. Attached to the side frame (tracks) of metal double and single hung windows. The mechanism also attaches to the window sashes, and keeps the sashes in position when raised.
Check Rail
The top rail of the bottom sash and the bottom rail of the top sash in a double hung window. These rails meet in the center of the
window when window unit is in closed position. Check rail equipped with either vinyl or rubber "bulb" weatherstrip.
Cladding
A protective layer or "skin" applied to the exterior of some doors and windows. Cladding can be made of aluminum or vinyl and can be of seamless (welded) design or installed in overlapping sections.
Closure
A hydraulic tube like device attached to the storm door panel and to the entry door jamb. The closure is adjustable and controls the speed in which the door panel closes.
Compression Weatherstrip
Linear bulb or fin type weather-stripping used on doors and windows. Used to seal door or window when unit is in the closed position with pressure applied to weather-strip.
Condensation
A natural occurrence on all windows that is caused by excessive humidity, or vapor, present in the air. When the vapor comes in contact with a cooler surface the vapor turns to droplets of water. (A glass of ice water in a warm room is a good example of condensation.)
Conduction
Energy transfer from one material to another by direct contact. This energy transfer is measured in BTUs.
Convection
Heat transferred by currents that flow from a warm surface to a colder surface.
Cripple Stud
For rough-in frame work; the 2 x 4 (Stud) which is positioned vertically underneath the header (header support)
and runs down to the bottom plate (2 x 4). Cripples are also used to fill in the gaps between the top plate and the header and the sill
plate and bottom plate.
Crown
Decorative trim nailed to the wall near the ceiling.
