IS 15345:2003 is the Indian Standard (BIS) for installation of frameless door and window shutters - code of practice. This code provides guidelines for the installation of frameless glass door and window shutters. It covers the requirements for materials like glass and hardware, workmanship, dimensional tolerances, and sealing methods to ensure a safe, secure, and weather-resistant installation.

Key Differences
≠IS 15345 is a highly prescriptive code specifically for frameless shutters, whereas international equivalents like AS 1288 are broader, performance-based standards covering all types of glazing.
≠The Indian standard provides specific minimum glass thicknesses (e.g., 10 mm for doors), while international codes typically require thickness to be determined by engineering calculations based on wind load, panel size, and support conditions.
≠IS 15345 refers to Indian standards for materials (e.g., glass to IS 2553, sealants to IS 11866), while international codes reference their respective national or regional standards (ASTM, BS, EN, AS).
≠The Indian standard provides explicit dimensional tolerances for the prepared opening (e.g., ±2 mm), which is less common in international codes that often defer to the system manufacturer's specifications.
Key Similarities
≈All standards mandate the use of safety glass (typically toughened/tempered) for frameless door shutters due to the high risk of human impact.
≈There is a common emphasis on maintaining adequate clearances or gaps around the glass perimeter to accommodate thermal expansion, building movement, and installation tolerances.
≈All codes recognize the critical importance of proper sealant application (typically structural silicone) for weatherproofing and, in some cases, structural bonding.
≈The requirement for using setting blocks made of non-deteriorating, resilient material (like neoprene or EPDM) to support the glass and prevent glass-to-metal contact is a universal principle.

Mandatory Glass Type for Doors
Toughened safety glass conforming to IS 2553 (Part 1).
Grade A safety glass (toughened or laminated) in areas subject to human impact.
AS 1288-2021
Minimum Glass Thickness for Doors
Not less than 10 mm.
Determined by calculation based on wind load and panel size; typically 10 mm or 12 mm for common door sizes.
AS 1288-2021
Clearance Gap (Glass to Frame/Wall)
About 3 mm.
3 mm to 6 mm, calculated based on panel dimensions and expected thermal movement.
BS 6262-3:2018
Opening Preparation Tolerance (Width/Height)
±2 mm.
Generally specified by the system manufacturer, often within ±1/8 inch (≈3 mm).
ASTM E2112-19
Setting Block Hardness
60 to 70 Shore A durometer.
70 to 90 Shore A durometer is commonly specified for setting blocks.

Minimum Edge Cover by Channel/Fitting
Not explicitly defined, but implied by fitting design.
Generally requires a minimum 'bite' or edge cover, often 8-10 mm, depending on the system.
