The various options of laminated glass processors offer make for more challenges when selecting a custom laminated glass product for an application. Typically, manufacturing &#;custom laminated glass&#; is the process of combining two or more panels of glass with an interlayer, which is placed in between the glass, bonding the panels together. Custom laminated glass is required in applications where safety and structural rigidity is compromised or subjected to high-pressure loads.
The two most popular options are SGP (ToughView) and PVB (ToughGuard).
Below we have gathered some key information to help you identify what laminate you require.
What is SGP?
SGP (SentryGlas® Plus) is a more rigid interlayer innovated by DuPont and produced by the supplier, Kuraray. The interlayer is 5 x stronger and up to 100 x stiffer than regular laminates such as PVB. This option provides the highest level of structural performance and edge stability for finished glass applications.
When would we use SGP?
Most commonly, when frameless balustrades are required without a handrail an SGP interlayer combined with toughened glass is required- ToughView. ToughView, when broken will hold together if a panel of glass was to break. Regular laminates, when broken are less rigid, meaning they are more likely to collapse and provide no support. This could be particularly dangerous if someone or something is to rest weight on the compromised glass. Edge stability is another factor why SGP is more suited in exposed edge applications as opposed to other interlayers like PVB, as it tends to absorb significantly less moisture, meaning less chance of de-lamination over time.

What is PVB?
PVB is another type of interlayer but does not have the same structural properties of SGP. When PVB laminated glass breaks, glass tends to hold together opposed to that of ordinary annealed or toughened glass. PVB is a more cost-effective solution and suitable product where higher structural performance is not required.
When would we use PVB?
Commonly PVB is used in windows and doors for both residential and commercial fit outs. When used it is highly recommended the edges are not exposed to high moisture or wet areas as this greatly increases the risk of the glass de-laminating and discolouring over a period of time.

Product Description
SGP Laminated Glass
SGP Laminated glass is one special laminated glass which is using SGP as interlayer. The laminated glass will tend to stay together and hold on SGP in broken, thus qualifying as a safety glazing material. The SGP laminated glass will stay standing when both sides glass are broken, it is about give times stronger and up to 100 times stiffer than PVB laminated glass. So the SGP laminated glass is widely used for the application which faces to bad weather like storms, hurricane and cyclone, not safety places and so on.
And the SGP yellow index is much smaller than PVB, so it is much more clear than PVB laminated glass, so high-end building project usually choose SGP laminated glass.
Key features of SGP laminated glass
Exceptional Strength: SGP laminated glass is renowned for its incredible strength. It is up to five times stronger and 100 times stiffer than traditional laminated glass. This exceptional strength makes it ideal for applications where safety and security are paramount.
Safety: In the event of breakage, SGP laminated glass holds together and remains intact, reducing the risk of injury from sharp glass shards. This makes it a preferred choice for buildings and structures that require high levels of safety, such as glass railings and overhead glazing.
Durability: SGP laminated glass is highly resistant to impact, weather, and UV radiation. This durability ensures that it maintains its structural integrity and appearance over time, even in harsh environmental conditions.

Clarity: Unlike traditional laminated glass, SGP has superior optical clarity. It minimizes distortion and maintains a crystal-clear view, making it suitable for architectural applications like glass facades and canopies.
Design Flexibility: SGP laminated glass can be customized to meet various design and aesthetic requirements. It can be combined with other types of glass, such as low-iron or colored glass, to achieve specific visual effects.
Blast Resistance: Due to its exceptional strength, SGP laminated glass offers enhanced blast resistance, making it suitable for high-security installations like government buildings and critical infrastructure.
Sound Insulation: SGP laminated glass also provides good sound insulation properties, which can help create quieter and more comfortable indoor environments.
UV Protection: It offers excellent UV protection, reducing the fading of interior furnishings and artworks by blocking harmful UV rays.
Easy Maintenance: Cleaning and maintaining SGP laminated glass is relatively straightforward, as it resists stains and can be cleaned with standard glass cleaning products.
