TABLE OF CONTENTS Numerous configurations of doors 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 latter three types.
The materials of construction for widows include: wood, steel and aluminum, vinyl, fiberglass, and combinations of these materials. However, the availability of different window configurations allows 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.
Whether the hollow metal frame are set up and welded or knocked down (KD), if they are not properly stored and installed in metal-framed drywall partitions or masonry openings, problems will arise, if not during actual construction, then certainly during the postconstruction period.
