Frame and sash main members are made of T6063-T6 aluminum alloy
extrusions. Typical extrusion wall thickness is .050 inches for
frame sections and .0465 inches for sash and screen sections.
Sash and screen extrusions are of tubular design for additional
strength and rigidity.
CONSTRUCTION: Frame components are assembled using double
screw coped corner construction and are secured by #6 x 3/4" 410
stainless steel screws. Frame depth with expander is 1".
Extruded aluminum expanders are used at the head, jambs, and
sill to compensate for opening irregularities. Frame head
utilizes a recess to capture the top of the upper sash for added
strength and rigidity. An extruded channel at the sill is used
for positive water drainage. An integral tongue extruded onto
the sill mates with the bottom of the lower sash for improved
rigidity and water control.
Active sash components are joined at the corner using mitered
corner construction and are fastened with zinc die cast self
locking corner angles. An extruded aluminum interlock is located
at the meeting rails for strength and improved resistance to air
infiltration. Weeps are employed at the bottom of each sash to
effectively vent any accumulated water from the sash.
GLAZING: Both sash are channel glazed using a flexible
vinyl glazing gasket along the perimeter of a single lite of
glass. Both sash may be re-glazed if necessary using existing
sash rails. Glazing options consist of clear, tinted, obscure,
and tempered glass.
SCREEN: Screen frame is made of tubular T6063-T6 aluminum
alloy extrusions and employs mitered corner construction,
fastened at the corner with self locking zinc die cast corner
angles. Screen cloth is of aluminum wire mesh held firmly in
place by a solid vinyl spline. HARDWARE: Sash are equipped with
spring loaded combination zinc die cast/stainless steel slide
bolts (with wire form handle, lower sash) that positively engage
punched holes in the master frame at predetermined locations
along the travel path of the sash. Stainless steel tension
springs located on one sash stile and one screen stile hold the
inserts firmly in place. Upper sash utilizes a stainless steel
lock plate that prevents sash movement from the outside.
Stainless steel wire form handle on screen allows screen to be
latched in place when fully closed.
FINISHES: All aluminum extrusions in master frame, sash,
and screen are finish painted with an electrostatically applied
enamel in a choice of three colors: White, Bronze, and Tan.
INSTALLATION: Installation of window shall be furnished
by others and should be done in a professional manner. Window
shall be set plumb and square in opening with no twisting or
distorting of the window, and shall be properly anchored. A
non-hardening sealant compatible with aluminum shall be provided
by the installer and applied by the installer in sufficient
quantity to provide a watertight seal between the window and
OPERATION: After installation, window shall operate
smoothly with no binding of either sash. Sash shall fully
interlock at the meeting rail when both sash are in the fully
closed position. Frame jambs shall be straight with no bowing in
or out and sash shall positively engage the frame jamb at all
points along the sash stile. Sash slide bolts shall positively
engage the holes in the frame jamb.
Sash and screen will be removable to the inside provided enough
clearance exists between the primary window and the storm window
WARRANTY: Window is covered by West Window Lifetime
