The core differences between U profile glass of different thicknesses lie in mechanical strength, thermal insulation, light transmittance, and installation adaptability.
Core Performance Differences (Taking Common Thicknesses: 6mm, 8mm, 10mm, 12mm as Examples)
Mechanical Strength: Thickness directly determines load-bearing capacity. 6-8mm glass is suitable for partitions and interior walls with short spans (≤1.5m). 10-12mm glass can withstand greater wind pressure and loads, making it suitable for exterior walls, canopies or enclosures with spans of 2-3m, and also offers stronger impact resistance.
Thermal Insulation: The hollow structure is the core of thermal insulation, but thickness affects cavity stability. U profile glass with a thickness of 8mm or more has a cavity that is not easily deformed, ensuring more stable thermal insulation performance. 6mm glass, due to its thinner cavity, may experience slight thermal bridging after long-term use.
Light Transmittance and Safety: Increased thickness slightly reduces light transmittance (12mm glass has a 5%-8% lower transmittance than 6mm glass), but the light becomes softer. Meanwhile, thicker glass has stronger shatter resistance—10-12mm glass fragments are less likely to splash when broken, offering higher safety.
Installation and Cost: 6-8mm glass is lightweight (approximately 15-20kg/㎡), requiring no heavy equipment for installation and featuring lower costs. 10-12mm glass weighs 25-30kg/㎡, needing matching stronger keels and fixings, which leads to higher installation and material costs.
Scenario Adaptation Recommendations
6mm: Interior partitions and low-span exhibition hall walls, ideal for pursuing lightweight design and high light transmittance.
8mm: Regular indoor and outdoor partitions, corridor enclosures, balancing performance and cost-effectiveness.
10mm: Building exterior walls and medium-span canopies, suitable for scenarios requiring certain wind pressure resistance and thermal insulation.
12mm: Exterior walls of high-rise buildings, coastal windy areas, or scenarios with heavy load requirements.
