COMERCIAL
Commercial Window Wall
Our commercial window wall range, in three mullion depths that trade sightline for wind load and span. 120S is the entry point at a 4 3/4" mullion depth, sized for low-rise commercial and podium levels up to 105 mph / 14’. 150S steps up to 5 7/8" for mid-rise elevations, taking greater wind load and span up to 120 mph / 24’ — its face width is 2 9/16" against 120S’s 1 15/16", so stepping up in depth does show on the elevation. 180S is the deepest at 7 1/8", for high-rise and high-wind elevations up to 135 mph / 65’, at the same face width as 150S so a tower can step up in structural capacity without a visible change in the facade grid. All three take casement, tilt & turn, awning and door elements on one sightline, glazed with pressure plates; U-factor and SHGC vary with the glazing or panel specified.
