What Are The Properties Of Laminated Glass:
Jun 02, 2017

1. Safety performance: Building laminated glass can withstand the impact of accidental penetration, even if the glass is broken, the pieces will still be with the PVB film together to reduce the risk of broken or glass fall, you can avoid the glass caused by personal injury Or property damage.

A. Wind pressure strength: in the working temperature ≤ 70 ℃, equivalent to the same thickness of 0.8 glass single glass; if the working temperature ≥ 70 ℃, equivalent to the same thickness of single glass 0.6 times. (PVB thickness of 0.38mm, 0.76mm and 1.52mm respectively) See JGJ113-2003 "Technical specification for construction glass".

B. Human impact safety requirements The maximum allowable area of laminated glass: see JGJ113-2003 "Technical specification for construction glass".

2. Sound insulation performance: PVB film has a damping function of the sound waves, so that the construction of laminated glass can effectively control the sound of the spread, play a good sound insulation effect. It is recommended to adjust in the following order, increase the damping (using laminated glass and increase the thickness of PVB) → increase the thickness of the insulating glass air layer → increase the thickness of the glass, by improving the sound insulation level of the glass by changing the specification parameters. The sound barrier STC value of the window is affected by the window frame, generally lower than the glass STC value of 1 to 3 level.

3. Security features: PVB film with special laminated glass can be made anti-bullet glass, anti-bomb glass and electromagnetic shielding glass.

4. Control of sunlight and UV protection: Building laminated glass can effectively reduce the transmission of sunlight, to prevent glare and block ultraviolet. Ultraviolet transmittance <1%.
