"I" is a numerical value which describes the area of the cross section of a member about the neutral axis perpendicular to the loads. "I" values determine the deflection characteristics of a member. (Members with higher "I" values deflect less than members with lower "I" values. [top]

International Building Code.
The IBC is an international building code that was created by the International Code Council in an effort to combine the three major building codes that were created by the three major model code groups in the US (Building Officials and Code Administrators International (BOCA), International Conference of Building Officials (ICBO), and the Southern Building Code Conference International (SBCCI). The International Building Code primarily covers non-residential construction. [top]

Interior measurement of the sealed unit opening. [top]

An extruded aluminium bracket designed to hold the base of the frame to the sill of the rough opening. [top]

A window composed of Insulating Glass (Also, Sealed Unit) [top]

Insulating glass is a combination of two or more panes of glass with a hermetically sealed air space between the panes of glass. This space may or may not be filled with an inert gas such as argon. [top]

Insulation refers to a material that has the ability to reduce heat or cold transmission. [top]

Insulating Bar; placed between two pieces of extrusion to prevent temperature transfer. [top]

The inside surface of a window or door. [top]

A corner coupler installed in a building that has the center of the coupler angles radius on the exterior side of the building. Interior corners are the reverse of an Exterior Corner. [top]

A method in which glass is secured in an opening from the interior of the building. [top]
