How To Choose Tempered Glass Thickness

Aug 09, 2026 Leave a message

Selection for Standard Residential Applications
‌Standard interior windows and partitions: Choose a thickness of 5mm–8mm; this balances transparency with practicality and offers excellent cost-effectiveness.
‌Street-facing units and balcony areas: Prioritize a thickness of 10mm–12mm; this provides superior wind-load and impact resistance, effectively handling vibrations caused by traffic.
‌Decorative glass for tabletops and countertops: 8mm is the optimal choice; it offers high load-bearing capacity and wear resistance, ensuring the glass resists scratching and deformation during daily use.

 

Selection for High-Risk Safety Applications
‌Shower enclosures, large floor-to-ceiling windows, and railings: Must use tempered glass with a thickness of 12mm or greater; lamination is recommended so that no sharp shards are produced upon breakage, maximizing home safety.
‌Horizontal surfaces exceeding 1.5m² or cantilevered structures: Minimum nominal thickness should be ≥8mm, with an upgrade to 10mm recommended to mitigate hidden risks associated with deformation under load or stress concentration at the edges.

 

Selection for Transportation and Industrial Applications
‌School bus side windows: Typically use 5mm tempered glass to reduce vehicle weight while maintaining safety standards.
‌High-impact applications (e.g., front windshields): Use 4+4mm laminated tempered glass (total thickness of 8mm) for enhanced penetration resistance.
‌Aquarium viewing windows and underwater camera ports: Select tempered glass ranging from 6mm to 40mm based on pressure requirements; custom specifications exceeding this range are available for specialized applications.
