All the four edges ofthe shutter shall be square. In case of double leaf doors, rebates shall be provided at the meeting of stiles.Rebates shall be splayed type and one third the thickness of the stiles.
48The glass sheets for glazing shall be fixed by teak wood beading having mitred joints as per drawings andshall be fixed by means of approved neoprene based adhesive and nailing, the spacing between the nailsbeing no more than 300 mm.All wooden surfaces shall be coated with 2 coats of approved make polyurethane with stainer mixed toachieve desired shade.The shutter shall be fixed to the door frame, by means of hinge @ minimum 3 hinges per leaf, maximumspacing of hinges being 600 mm or as per drawing with suitable sized screws.The shutter when fitted to the frame shall satisfy all operational aspects of the door like smoothmovement, proper closing against the door frame etc.7.4 SPECIFICAITON FOR STEEL / ALUMINIUM DOORS, WINDOWS & VENTILATORS7.4.1 Steel windows & VentilatorsSteel windows, ventilators shall in general conform to IS 1081, IS 1038, IS 7452.7.4.2 Materials7.4.2.1 Rolled Steel SectionsRolled steel sections for the fabrication of steel windows, ventilators shall conform to IS 7452.7.4.2.2 Glass panesGlass panes for glazing purpose shall be as specified in item description. All glass panes shall haveproperly squared corners and straight edges. Glass panes shall be of following types in accordance withitem description.i. 4mm thick transparent sheet glass conforming to IS 2835 (wt. 7.2 kg / m)ii. 5.5 mm thick wired glass conforming to IS 5437.iii. 6.3 mm thick laminated safety glass conforming to IS 2553.7.4.2.3 WorkmanshipThe profile and type of windows, Ventilators (glazed, partly glazed / louvered, side hung / top hung /fixed shutter, composite) shall be as per drawings.The frames shall be constructed of sections cut of size and mitred. Corners shall be welded to form afused welded joint. Process of welding shall be flash butt welding. The welded joints shall be grinded tosquare and flat edges.Where larger units are to be formed by coupling individual units, the mullions, transforms shall be beddedin mastic to ensure weather tightness. Mastic shall be applied liberally to the channels of the outside framesections before assembly, and the two units being coupled shall be drawn together tight with clamps, themastic being squeezed out and cut off neatly when the units shall be screwed together tight.Where fixed glazing units are placed over openable units a push fit weather bar shall be provided.Before glazing, all opening parts shall be checked for their operational smoothness. The frame shall becompletely cleaned and bedding putty shall be placed in the rebate before glazing. Glass then shall becushioned into the bedding and shall be fronted with front putty in a manner so as to enable the painting tobe done upto the sight line. The back putty oozing out over the glazing rebate shall be cut off square andsmoothed down.For panes exceeding 600 x 300mm in size, glass shall be secured by special glazing clips inserted in holesalready provided in the steel sections, before applying the front putty.
