PUCA - Réemploi et reconfiguration thermique des fenêtres en fin de viePARTIE 1The replacement sash remained operable despite the central hvac. To solve the problem of balancingthe heavier glazing, the upper sash were fixed in place, and the lower sash were doublycounterweighted in both pockets. All missing hardware was replaced with replicas.POWER HOUSE ELLIS ISLAND NATIONAL MONUMENT NEW YORK CITYUnlike the Main Building to the south, the windows of the more modest Power House, which werenot stabilized in the 1970s, were determined to be beyond repair. All windows in the building, mostlydouble-hung including the most minor casements and a group of horizontal pivot sash, werereplaced brick to brick with new operable units. As in the Main Building, the objectives of exteriorrestoration were balanced with interior use. Most windows did not require insulated glazing and,apart from the introduction of vinyl weatherstripping, matched the original millwork exactly. Severalunits in spaces planned for office use were equipped with insulated glass, requiring an enlargementof the center muntin from I-in. to 1 1/2-in., a modification that is visible upon close inspection. Agreater visual impact, however, resulted from the substitution of the original clear plate glass withobscure glass in windows where the incinerator storage was housed. By introducing a nonuniformpattern of glazing, the effect, whether· intentional or not, softened the hard edge of the newwindows in this otherwise weathered building.Juin 2012Les Bâtisseurs d’Emmaüs48
