PERFORMANCE
A. Basic Function
1. Fill, cover, close, or otherwise protect all glazed openings in the exterior walls (other than
doors) so that the entire exterior enclosure functions as specified, using windows and
other opening elements as specified, without using components that must be installed at
changes of season.
2. The elements comprising exterior windows and other openings include windows, fixed
glazing other than glazed walls, ventilation openings, protection devices for openings,
and elements that form or complete the openings, unless an integral part of another
element.
3. Where exterior window and other opening elements also must function as elements
defined in another element group, meet requirements of both element groups.
4. Brand Names: Where brand names are listed, they represent the Basis of Design unless
those items are identified as approved proprietary items in project requirements.
B. Amenity and Comfort
1. Thermal Performance of Elements Forming Exterior/Interior Separation: Per Code.
2. Air Infiltration: Per Code.
C. Appearance
1. Sight Lines of Glazed Areas: Provide maximum glazing area with minimum interruption
by framing members.
2. Frames: Construct frames of openings to give a flush appearance without shadow lines.
D. Health and Safety
1. Fire Resistance: Rating as required to maintain fire resistance rating of exterior wall in
which they occur.
2. Operable Openings
a. Where operable units are indicated, provide projecting in- or out-swinging units
unless otherwise indicated.
(1) Provide in-swinging projecting (“hopper”) units at all first-floor locations and
other locations subject to pedestrian traffic unless otherwise indicated.
b. Provide stops to limit openings so that a 5” diameter sphere will not pass through.
Provide stops that require special tools for adjustment or removal.
c. Provide insect screens to keep insects, birds, and animals out.
