The standard specifies several aluminium alloys for fenestration products: extruded window sections should use an alloy conforming to HE9-WP under IS:733-1956; hollow aluminium profiles are to comply with HV9-WP as per IS:1285-1958; cast hinges for top-hung ventilators must meet A-5-M designation according to IS:617-1959; and extruded hinges for top-hung ventilators should adhere to HE10-WP or HE30-WP alloys per IS:733-1956. These selections ensure appropriate strength, durability, and corrosion resistance.
Composite assemblies are identified by a modular coding system that includes width, type, and height components separated by slashes. Width and height are expressed in module counts, while the type uses letter codes such as C for centre-hung, F for fixed glass, H for horizontal glazing bars, N for no horizontal bars, S for side-hung, and T for top-hung shutters. For example, a door 12 modules wide by 21 modules high, side-hung with horizontal glazing bars, is denoted as 12HS21. Coupled units combine these designations, for instance, 6HS12 / 12HS21 / 6HS12 for side-coupled window-door-window setups.
The standard employs a modular system where one module is approximately 8.25 cm. Dimensions for doors, windows, and ventilators are measured to the outer frame edges and expressed in modules for width and height. Clearances of about 1.25 cm are allowed on all sides for installation. Common module counts include 6, 10, 12, 13, and 21, corresponding to specific centimeter values. This modular approach simplifies coordination with building openings and standardizes fenestration dimensions.
Recommended hinges include cast or extruded aluminium alloys compliant with IS standards. Projecting hinges are typical, with widths ranging from 50 mm for windows to 67 mm for doors. Non-projecting hinges may be used if mutually agreed upon. Hinges feature stainless steel or anodized aluminium alloy pins and are fixed into frame slots by riveting or welding. Locking handles are cast aluminium with anodized finishes and utilize a two-point nose engaging mechanism with aluminium strike plates. Friction hinges incorporate stainless steel washers to prevent loosening.
Glazing must be installed on the exterior side of the aluminium frames. Glass panes should weigh at least 7.5 kg/m², be free from defects, with squared corners and straight edges. Standardized glass sizes are provided in detailed tables, covering various glazing bar types such as fixed, centre-hung, side-hung, and top-hung. Glazing clips, usually four per pane (six for larger doors), may be used based on agreement, spaced at about 30 cm along horizontal bars or aligned with vertical frame slots. Fixing screws and lugs vary by substrate and installation type, with galvanized wood screws for wooden rebates, longer screws for non-rebated concrete or brick, and adjustable steel lugs with bolts for masonry or steel work.
