Laminated glass is formed as a sandwich of 2 sheets of glass, between which is bonded together with a tough and thermoplastic polyvinyl butyral (PVB) interlayer under heat and pressure.

 

 

Applications：

1. Architecture&Furniture

2. Automotive windshield

3. Bullet/burst-proof purpose

 

Specification ：

Max. size：

For architecture:2438mm x 6000mm

 

For automobile:991mm x 2197mm

 

 

Standard Colors Of PVB Interlayer

Laminated glass with a tinted interlayer will beautify the buildings and harmonize their appearances with surrounding views which meet the demand of architects。

 

May crack under impact, but typically remains intetral. Splinters and sharp fragments adhter to interlayer.

 

The PVB interlayer withstands penetration from impact. Even if the glass cracks, splinters will adhere to the interlayer and not scatter. In comparison with other kinds of glass, laminated glass has much higher strength to resist shock, burglary, burst and bullets.

 

Example 
• 6.38 Laminated glass is constructed of 2 x 3mm panes of glass with 1 x 0.38mm PVB interlayer 

The second way laminated glass construction can be identified is through the number of panes and number of PVB interlayer’s 

Example 
• 6.4 Laminated glass can also be know as 33.1 as this has 2 x 3mm panes of glass (33) combined with 1 PVB interlayer. 

Safety: Laminated Glass breakage properties and impact resistance are determined and classified in accordance with EN 12600: Glass in building. Pendulum test. Impact test method and classification for flat glass.

Security:The protection provided by laminated glass against burglary or vandalism is determined and classified according to EN 356: Glass in building. Security glazing. Testing and classification of resistance against manual attack.

Explosion Resistance:Minimise the risk of injury from flying glass shards, the performance is determined and classified in accordance with EN 13541: Glass in building. Security glazing. Testing and classification of resistance against explosion pressure.

Noise Reduction:Laminated glass has natural sound dampening capabilities which may be measured in accordance with EN 140: Acoustics. Measurement of sound insulation in buildings and of building elements. The values may then be expressed according to EN ISO 717: Acoustics. Rating of sound insulation in buildings and of building elements.

Ultra-Violet Radiation:Laminated glass can be used to protect materials from fading by blocking up to 99% of ultra-violet light from the sun.
