Laminated Glass
Hurricane and Seismic Resistance – The glass remains bonded together after breakage, helping maintain the building envelope during hurricanes, earthquakes, and other extreme events, thereby enhancing overall building safety.
Excellent Acoustic Insulation – The PVB interlayer effectively dampens sound transmission, significantly reducing external noise and creating a quieter indoor environment.
UV Protection – Laminated glass blocks more than 99% of harmful ultraviolet (UV) radiation, helping protect furniture, curtains, artwork, displays, and other interior furnishings from UV damage and fading.
| Glass Substrate Thickness (mm) | 3.2--19 |
| Overall Laminated Glass Thickness (mm) | 6.38--60 |
| Glass Types Available | Symmetrical Safety Laminated Glass, Asymmetrical Safety Laminated Glass, Bullet-Resistant Glass, etc. |
| Maximum Size (mm) | 2850X10000 |
| Minimum Size (mm) | 300X300 |
| Interlayer Types | PVB / SGP Interlayers (0.38 mm, 0.76 mm, 1.14 mm, 1.52 mm, 2.28 mm, etc.) |
| Interlayer Colors | Ultra Clear, Clear, Opal White, Ceramic White, Blue, Gray, Green, and Pink |
Minimum PVB Interlayer Thickness for Standard Laminated Glass
| Glass Type | Glass Substrate Thickness (mm) | PVB Interlayer Thickness (mm) |
| Standard Flat Laminated Glass | ≤5 | 0.38 |
| 6--8 | 0.76 | |
| 10--12 | 1.14 | |
| ≥12 | 1.52 |
Minimum PVB Interlayer Thickness for Flat Tempered or Heat-Strengthened Laminated Glass
| Glass Type | Glass Substrate Thickness (mm) | PVB Interlayer Thickness (mm) | ||
| Short side ≤ 800mm | Short side > 800mm | Short side > 1500mm | ||
| Flat Tempered or Heat-Strengthened Laminated Glass | ≤6 | 0.76 | 1.14 | 1.52 |
| 8--10 | 1.52 | |||
| 12--15 | 1.52 | |||
| 19 | 2.28 | |||
| ≤12 | 1.90 | |||
| ≥15 | ≥2.28 | |||
Note: For flat tempered or heat-strengthened laminated glass, when both the height and width exceed 800 mm and the aspect ratio is close to 1:1, bow distortion during the tempering process becomes more difficult to control, which may result in a dish-shaped deformation. In such cases, the PVB interlayer thickness should be increased by an additional 0.38 mm beyond the specified minimum requirement.
Minimum PVB Interlayer Thickness for Curved Tempered Laminated Glass
| Glass Type | Glass Substrate Thickness (mm) | PVB Interlayer Thickness (mm) | |
| Bending Radius ≥ 3 m | Bending Radius ≤ 3 m | ||
| Curved Tempered Laminated Glass | ≤6 | 1.52 | 1.90 |
| ≥38 | 2.28 | ||
Note: The glass substrate thickness shall be based on the thickness of the thicker lite in the laminated glass assembly. For irregular-shaped, notched, drilled, oversized, extra-long, or extra-wide glass, the PVB interlayer thickness should be increased by 0.38–0.76 mm, depending on the specific application. Laminated glass constructed with a thickness difference greater than 2 mm between the two glass lites is not recommended, as the uneven load distribution may adversely affect its structural performance.
