and durability. This thermal window shall be constructed from specially designed, heavy gauge,
extruded sections split with a structural thermal break in accordance with Northern Building
Products, Inc. standards and drawings. Frame sill shall have a nominal thickness of not less
than 0.078”. The aluminum extrusions for main frame and sash sections shall be of 6063-T6
alloy and shall have a minimum ultimate tensile strength of 22,000 P.S.I. and a yield strength of
16,000 P.S.I.
CONSTRUCTION:
All joints of the sash and master frame shall be butt-type construction, and shall be secured by
means of screws into integral screw ports. Sash shall interlock at center meeting rail. All
moving sash shall have an extruded push/pull handle rail.

continuously adjustable by use of a screwdriver and without requiring removal of a sash.
Rollers shall have nylon QUIET-TREADS.
All fasteners, screws, rivets and other miscellaneous fastening devices shall be of aluminum,

THERMAL BARRIER:
The thermal insulator shall be poured in place polyurethane. The polyurethane shall be selfadhering to the adjacent aluminum surfaces. After the polyurethane becomes solid, aluminum
sections shall be debridged, preventing any contact between interior and exterior metal. There
shall be a minimum of 3/8” separation between the interior and exterior metal surfaces after the
debridging process.
OPERATION:
Both operating sashes shall operate freely and be removable when in an unlocked position, for
ease of window cleaning. All operating sash surfaces shall be completely separated from
metal-to-metal contact through the use of woven pile, vinyl, or nylon.
PERFORMANCE:
Manufacturer shall furnish an affidavit of certified test report from an independent testing
laboratory indicating that the window has satisfactorily met the performance requirements for
HS-HC50 of AAMA/NWDA 101/I.S.2-97 for windows and doors.
GLAZING:
Sash shall be glazed with 7/8” sealed insulating units. Triple insulating glass is optional. Glass
shall be set in channel type gaskets (marine glazing), which shall be of material compatible
with aluminum, and shall be resistant to deterioration by all forms of weathering, and shall be
suitably retained to maintain a watertight seal between glass and surrounding frame. Flexible
vinyl to be of commercial standard.
GLASS:
Glass shall not be less than “B” quality. Standard factory glazing shall be single strength, 7/8”
insulating glass. Triple insulating glass units shall also be available.
EXTERIOR PANNING SYSTEM: (Optional)
Exterior panning, where used, shall be extruded aluminum of 6063-T6 aluminum alloy, 0.062”
thick. Aluminum section shall be one piece designed to lock around the entire window frame,
shall completely cover exterior of the window frame, and shall be a completely weather tight
connection, but shall allow unrestricted expansion and contraction of panning members and
window frame. The panning section shall be secured at the corners with screws into extruded
