A scale drawing of any side of a building; or, refers to the height above a specific reference point, especially sea level. [top]

The cap inserted in the ends of deflection channel retainer clips against rough opening jambs; usually made of aluminium sheet metal or PVC. [top]

The aluminium component installed in the end of a deflection channel against rough opening jambs. Used to extend the deflection channel to the jamb and provide a base to caulk on for the external sealing process. [top]

A program sponsored by the US Department of Energy which establishes minimum performance standards for a window to be recognized as energy efficient. Three different sets of standards for U-Value and solar heat gain have been established for three different climate zones in the US. [top]

Exterior length refers to the heel dimension of the exterior height of a frame or installation component. (Bypass frames have taller exterior heights to allow bypass slab to be hidden behind it, the interior height is shorter so the frame can rest and be secured on top of the slab to support the weight of the window.) [top]

Any additions to the original scope of work defined by the contract are considered extra's to the contract. [top]

The process in which a heated material is pushed through a die, used to produce aluminium, vinyl (PVC), and other profiles or components used in the production of windows and doors. Term also is used to refer to the profiles or lineal manufactured by this process and used to make window and door components. [top]
