TABLE OF CONTENTS Numerous configurations of doors and and windows are in use in residential, commercial, and industrial construction today.
Sliding, revolving, folding, and vertical rise doors are specified in some projects, but it is the rare construction project that does not include swinging doors either wood or metal or laminate clad. This section emphasizes these later three types.
The materials of construction for windows include: wood, steel and aluminum, vinyl, fiberglass, and combinations of these materials. However, the availability of different window configurations allow for a multitude of fenestration configurations: single and double hung, fixed lights, casements, sliders, awnings, and pivots to meet specific architectural designs. This section is devoted to general window design and materials of construction.
Commonly referred to as hollow metal, these doors and frames are available in many standard sizes and configurations and any number of custom design variations. The design and classification standards are established by the Steel Door Institute (SDI) for grades, sizes, metal gauges, and hardware locations.
