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.

Ultra Clear Laminated Glass: What Is It and Advantages

What is ultra clear laminated glass?

Ultra clear laminated glass is a safety glass made of two or more pieces of ultra clear glass sandwiched between one or more layers of ultra clear PVB/SGP film, which are bonded under high temperature and high pressure within a certain period of time.

Advantages of ultra clear laminated glass

1. High safety: It has high impact resistance and is not easy to break. Even if it is broken, the glass will stick firmly to the film, avoiding human injury caused by the falling fragments.

2. Sound insulation: Ultra clear laminated glass can reduce noise by 30-40 decibels and create a quiet environment

3. Excellent UV protection: Ultra clear laminated glass can block 99% of UV rays

4. Beautiful: Joy Shing ultra clear laminated glass is made of the best materials and is of high quality. The glass transmittance reaches more than 90%, making it visually clearer and free of bubbles.

Safety Insulated Glass: What It Is and Advantages

 What is safety insulated glass?

Safety insulated glass is a glass component that consists of two or more pieces of glass, separated by an aluminum frame filled with high-efficiency molecular sieves, and the edges are sealed with high-strength sealant.

The structure of safety insulated glass

Advantages of safety insulated glass

1. Heat insulation and energy saving: The dry and sealed gas middle layer has good heat insulation and heat preservation properties, which can effectively reduce the U value of the heat transfer coefficient, thus greatly reducing the temperature difference between indoor and outdoor heat transfer. If inert gas is filled, the U value will be lower and the energy saving effect will be better.

2. Sound insulation: Safety insulated glass has very good sound insulation performance. The 6+12A+6 structure insulated glass can reduce the noise by more than 30 decibels. The noise reduction performance can be improved if inert gas is filled.

3. Anti-condensation: If the temperature difference between indoor and outdoor is large, condensation will form on single-layer glass, but condensation will not easily form on the surface of insulated glass. Due to the influence of the air spacer, even if the outer glass is very cold, the inner glass will not become cold easily, thus eliminating and reducing condensation on the inner glass.

Safety insulated glass in different sizes

Safety insulated glass is widely used in building doors, windows and curtain walls due to its excellent sound insulation, heat insulation and anti-condensation properties. As a professional glass manufacturer, Joy Shing Glass can customize and deeply process glass as required. Integrated glass solutions for your construction projects.
