**************************************************************************
[Provide mullions between multiple window units which meet the design
pressure of [720] [1440] [1920] [_____] Pa [15] [30] [40] [_____] psf.]
Provide mullions with a structural thermal break. Secure mullions and
transom bars to adjoining construction and window units in such a manner as
to permit expansion and contraction and to form a weathertight joint.
[Where window cleaner anchors are required, reinforce mullions and anchor
to adjoining construction so as to provide safe and adequate support.]
Provide mullion covers on the interior and exterior to completely close
exposed joints and recesses between window units and to present a neat
appearance. [Provide special covers over structural support at mullions as
indicated.]
2.2.7
Accessories
Provide windows complete with necessary hardware, fastenings, clips, fins,
anchors, glazing beads, and other appurtenances necessary for complete
installation and proper operation. [Furnish extruded aluminum subframe
receptors [and subsill] with each window unit.]
2.2.7.1
Hardware
AAMA 101. The item, type, and functional characteristics shall be the
manufacturer's standard for the particular window type. Provide hardware
of suitable design and of sufficient strength to perform the function for
which it is used. Equip all operating ventilators with a lock or latching
device which can be secured from the inside.
2.2.7.2
Fasteners
Provide concealed anchors of the type recommended by the window
manufacturer for the specific type of construction. Anchors and fasteners
shall be compatible with the window and the adjoining construction. Provide
a minimum of three anchors for each jamb located approximately 150 mm 6
inches from each end and at midpoint.
2.2.7.3
Window-Cleaner Anchors
**************************************************************************
NOTE: Window-cleaner anchors should be shown and
specified for windows having sills more than [1800
mm] [6 feet] above grade, adjoining balconies, or
adjoining roofs, unless window cleaning methods at
activity make use of anchors unnecessary.
Coordinate window cleaning procedures and
requirements with using activity. When requested by
using activity, removable or tilting-type sash may
be provided instead of anchors. Removable or
tilting-type sash may be specified as Contractor
option when these units are desired by using
activity and are economically competitive with
double-hung sash equipped with anchors. When
appropriate, add the following at end of paragraph
SECTION 08520N
