and where required by local codes and ordinances. Under these conditions, all
metal doors and frames are completely factory finished and salt spray,
humidity, and weathering tested. Metal covered wood core doors are less
desirable than hollow metal doors since the sheet metal cladding is lighter
and subject to faster deterioration. Where sound transmission qualities are
required, specify composite construction steel doors with a Sound Transmission
Coefficient (STC) rating.
8.4.2
Fire-Rated Doors and Frames. Strict requirements for fire doors
and frames (i.e., labeled doors) preclude changes or modifications except when
approved by the fire protection engineer. However, to assure maximum
protection for fire doors with ferrous metal components, ensure all such
metals are hot-dip galvanized; and, in addition, frames are shop primed.
8.4.3
Glass Doors. Where design or the aesthetics dictate solid glass or
metal framed glass doors, frames are stainless steel, type 304 or 316 in 12,
14, or 16 gauge, polished and finished except where the exterior doors are in
a well protected area in which case aluminum (clear anodized after
fabrication) may be considered.
8.4.4
Plastic Laminate Faced Doors. Use plastic laminate covered doors
primarily for interiors; however, under given design parameters, they could be
used as an exterior door where weather protection is maximized (such as where
door is on the lee side of the building or where the building overhang is
sufficient to protect the door from wind-driven rain). These doors are also
of hollow, mineral or solid cores, with high pressure decorative laminate
facings on all exposed edges. Ensure exposed edges (top and bottom) are
weatherproof treated against moisture and water penetration if door is to be
used for exterior purposes.

8.5.1
Window Selection. Base the selection of window types on the
standard building design criteria including wind conditions and frequency of
tropical storms. Operable windows of the awning or projected type are the
recommended options. Jalousie type windows are less desirable for air
conditioned areas because of their high air and water infiltration factors.
8.5.2
Aluminum Windows. Aluminum windows, whether fixed or operable, are
the designer's only choice. Aluminum does oxidize readily and the finish
specified should be anodic (clear or colored). Alternatively, factory-applied
fluorocarbon or electro-deposited epoxy finishes provide excellent corrosion-
resistance and color retention. For added protection to anodized finishes,
select a clear aliphatic urethane finish factory-applied over the anodic
coating. Use stainless steel hardware for operable parts.
8.5.3
Other Windows. Do not use steel, wood, and plastic-clad wood
windows in tropic regions.
