3 Windows Curtain Walls Entrances torefronts Main Frame Construction The frames have a depth of 3 7/8 and are constructed of 6063-T6 aluminum alloy. The nominal material wall thickness for the frame is.080, and the sill has a minimum wall thickness of.094. Corners are of screw spline construction and sealed. ee llustration 1. ash Frame Construction The sash consists of aluminum members with.080 nominal material wall thickness of 6063-T6 alloy. Corners are of screw spline construction and sealed. Dual weather-stripped continuous interlock at the sash meeting rail(s) offers superior weathering and structural performance. ee llustration 2. llustration 1 Thermal Barrier The upper sash meeting rail is thermally improved using two-part, high density polyurethane. ll remaining members are thermally isolated with two thermal struts consisting of glass reinforced polyamide nylon, mechanically crimped in raceways extruded in the exterior and interior extrusions. ee llustration 3. Weather tripping ll sash are weather-stripped with FN-EL or equal. Two holes per sash and two slots through the window frame facilitate weepage. creens creen frames are extruded 6063-T6 aluminum alloy. creens are easily removed by retracting two plungers located on the interior face of the screen frame near the sill at each jamb. Full or half screens are available. 18 x 16 mesh screens are available in fiberglass and.011 diameter aluminum. 18 x 18 mesh screens are available in.009 diameter stainless steel. llustration 2 Hardware locks, access controlled sweep locks, pole ring sweep locks, and keepers are of cast white bronze with a U25D finish.
