The Difference Between Ultra Clear And Clear Tempered Glass, Usage Suggestions

The video introduces the difference between ultra clear tempered glass and clear tempered glass, the reasons for the difference, and usage suggestions.

The data shows that the visible light transmittance of 8mm clear tempered glass is 88%, and the visible light transmittance of 8mm ultra clear tempered glass is 91%. The reason for the difference between the two products is that clear tempered glass contains iron sulfide and nickel sulfide, while ultra clear tempered glass contains low iron content. Therefore, ultra clear tempered glass has a lower self-explosion rate. In actual use, if there are no extremely high requirements for light transmittance and self-explosion rate, clear tempered glass can meet most needs. If you require extremely low self-explosion rate, we recommend heat soaked test. Joy Shing Glass can provide integrated glass solutions according to your project. If you have this need, you can contact us at any time.

The King of Safety Glass - Laminated Glass

Laminated glass, often referred to as the king of safety glass, is a remarkable building material. It is composed of two or more layers of glass, bonded together by a layer of polyvinyl butyral (PVB) interlayer. This unique construction gives laminated glass its exceptional properties, making it a preferred choice for a wide range of applications where safety, security, and aesthetics are paramount.

Laminated Glass

Characteristics of Laminated Glass:

Safety and Security: One of the most significant advantages of laminated glass is its ability to hold together when shattered. Unlike ordinary glass, which breaks into sharp and dangerous shards, laminated glass remains intact, thanks to the interlayer. This property reduces the risk of injuries, making it an ideal choice for applications where safety is crucial, such as automotive windshields and building facades.

Impact Resistance: Laminated glass offers excellent resistance to impact from external forces. It can withstand blows from rocks, debris, or even attempted break-ins, providing enhanced security against burglary and vandalism. The interlayer absorbs and dissipates the energy from impacts, preventing the glass from shattering and maintaining its structural integrity.

Sound Insulation: The PVB interlayer in laminated glass helps to dampen sound transmission, making it an excellent choice for environments that require noise reduction. Whether it's for residential buildings near busy streets or office spaces seeking a peaceful working environment, laminated glass effectively reduces noise pollution, providing tranquility and comfort.

UV Protection: Laminated glass offers reliable protection against harmful ultraviolet (UV) rays. The interlayer filters out a significant portion of UV radiation, which can cause fading and damage to furniture, artwork, and other interior elements. This feature is particularly valuable in applications such as museums, galleries, and homes with valuable possessions.

Laminated glass, with its unmatched safety, security, and aesthetic qualities, has rightfully earned the title of the king of safety glass. Its ability to withstand impacts, resist breakage, and provide protection against UV rays has made it an indispensable material in various industries. Whether it's for automotive, architectural, or interior design applications, laminated glass continues to redefine safety standards and elevate the functionality and beauty of modern structures.

Application of Laminated Glass

PVB Film VS SGP Film In Laminated Glass

Laminated glass is composed of two or more pieces of glass with one or more layers of organic polymer interlayer sandwiched between them. After special high-temperature pre-pressure (or vacuuming) and high-temperature and high-pressure process, the glass becomes A composite glass product that is permanently bonded to an interlayer film.

Laminated glass is a widely used glass in the field of architectural glass, and is also called safety glass. Commonly used laminated glass films include: PVB and SGP.

PVB film has good safety, sound insulation, ultraviolet resistance, cold resistance, and impact resistance. However, PVB film has poor water resistance and is easy to peel off when exposed to moisture for a long time. It is currently the most widely used interlayer material for architectural glass and automotive glass.

SGP film has good toughness, strength, light transmittance, moisture resistance, bending resistance, aging resistance, and UV protection. SGP laminated glass is mainly used in glass lighting roofs, glass exterior windows, curtain walls, etc.

Performance comparison of PVB film and SGP film

1. Strength. The load-bearing capacity of SGP film laminated glass is 2 times that of PVB film laminated glass of the same thickness; the tear resistance strength is 5 times that of PVB film.

2. Bending resistance. Under the conditions of equal load and equal thickness, the bending deflection of SGP film is only 1/4 of that of PVB film. When the glass is broken, the bending deformation of SGP film laminated glass is small and it is not easy for the whole piece to fall.

3. Strong stability and moisture resistance. SGP film is colorless and translucent, has good weather resistance and is not prone to yellowing. The yellowing coefficient of SGP film is less than 1.5, while the yellowing coefficient of PVB film is 6~12, so SGP is mostly used in ultra clear laminated glass.
