How to confirm the best PVB thickness for your project?

There’s an updated posts for this article,click: PVB thickness for facade laminated glass

Laminated glass is widely used in buildings,but confirming the best PVB thickness for your project to save the most costs and guarantee the glass quality is quite important.

PVB thickness are usually 0.38mm,0.76mm,1.14mm,1.52mm,2.28mm.Here is a guideline -PVB interlayer thickness for different laminated glass-Annealed laminated glass,tempered laminated glass,heat strengthened laminated glass,curved laminated glass.

Bulletproof glass,aquarium glass,and multi layer laminated glass are excluded.

1.Annealed laminated glass

Glass Types	Glass thickness	PVB thickness
Glass Types	Glass thickness	L≤800mm	L>800mm
Annealed laminated glass	≤6mm	0.38	0.38
	8mm	0.38	0.76
	10mm	0.76	0.76
	12mm	1.14	1.14
	15,19mm	1.52	1.52

2.Heat treated laminated glass-Tempered lami,heat strengthened lami

Glass Types	Glass thickness	PVB thickness
Glass Types	Glass thickness	L≤800mm	800<L≤1500	L>1500MM
Heat treated laminated glass	≤6mm	0.76	1.14	1.52
	8-12mm	1.14	1.52	1.52
	≥15mm	1.52	2.28	2.28

Note:For irregular shape laminated glass,or 2 pieces laminated glass with thickness difference over 3mm,an extra 0.38mm PVB is required.

3.Heat treated curved glass

Glass Types	Glass thickness	PVB thickness
Glass Types	Glass thickness	R>3000mm	R≤3000mm
Curved heat treated laminated glass	≤8mm	2.28	3.04
Curved heat treated laminated glass	≥10mm	3.04	3.04
