Tempered vs Laminated Glass: Differences, LA–LX Codes and Mandatory SNI 9144
Choosing tempered vs laminated glass for doors, shower screens, railings or canopies is now also a compliance question. Industry Regulation 22/2026 makes SNI mandatory for both: laminated safety glass follows SNI 9144-1:2022 and tempered (toughened) safety glass follows SNI 9144-2:2022. The obligation applies 6 months after the regulation was promulgated on 31 July 2026.
Key Facts
- Laminated safety glass = two or more glass sheets bonded with an interlayer; if broken, fragments stay attached to the interlayer (2026-07-31, source: Ministry of Industry Reg. 22/2026 (promulgated 31 Jul 2026), Pasal.id).
- Tempered safety glass = pre-stressed glass that breaks into small, blunt pieces (2026-07-31, source: Ministry of Industry Reg. 22/2026 (promulgated 31 Jul 2026), Pasal.id).
- Laminated types are coded LA, LD, LHS, LM, LP, LR, LT and LX (Article 2(4)) (2026-07-31, source: Ministry of Industry Reg. 22/2026 (promulgated 31 Jul 2026), Pasal.id).
- The SNI obligation applies 6 months after the regulation takes effect; certified products must carry the SNI mark and an electronic mark (2026-07-31, source: Ministry of Industry Reg. 22/2026 (promulgated 31 Jul 2026), Pasal.id).
Tempered vs laminated glass: the main differences
- Tempered: strong against impact and heat, breaks into small granules. It cannot be cut or drilled after tempering, so sizes and holes must be final before ordering.
- Laminated: fragments stay on the interlayer so the opening stays closed; suited to skylights, canopies, railings and upper-floor windows.
- Laminated tempered glass (code LT) combines strength with fragment retention.
Which to use where
- Shower screens and glass doors: tempered is usually enough.
- Overhead glass (canopies, skylights) and railings: prefer laminated or laminated tempered.
- Ask suppliers for the SNI mark or certificate.
Transition
Glass produced or imported before the regulation took effect may still be sold to end users. Test samples and R&D lots of up to 10 sheets are exempt.
