The demand for laminated glass is rising with the passing day, but most customers are confused about the variety of Interlayer film available in the market. What is the difference between the interlayers, and how can you select the best option? The most common interlayers used in Australian marketing for constructing buildings are PVB and EVA.  

The difference between PVB and EVA interlayer

Both PVB and EVA interlayers are good options for manufacturing laminated glass. Both types of interlayer films get used by glass manufacturers. Both options have got their features and properties. Now you might be thinking about which inter-layer is better or the difference between them. Let’s talk about the differences in detail now:

PVB laminated glass

The most common layer is PVB, which stands for polyvinyl butyral. Due to its flexibility and optical clarity, most glass manufacturers use this interlayer film material. Standard PVB is combined with annealed glass so the glass processors and glaziers can easily cut the glass after lamination. PVB is quite famous because, for urgent repairing of A-class glass or replacement, the professional professions prefer PVB interlayer film. The reason behind this preference is that it requires less processing.

For customized specifications and size for a longer lead time, PVB is preferred over any other inter-layer film.

PVB Inter-layer film applications

Let’s talk about the applications of PVB inter-layer:

  • Windows and residential doors
  • Shop windows and fronts
  • Overhead gazing
  • Internal glass partitioning
  • Hospitals, schools, and buildings
  • Internal glass balustrades

PVB interlayer film availability

PVB interlayer is available in the following details:

  • Acoustic PVB
  • Colored PVB
  • Solar performance PVB
  • Tinted PVB
  • Structural PVB

Benefits of using PVB

Following are the benefits that you will have to consider PVB inter-layer film:

  • PVB inter-layer will filter 99% of UV rays coming from the sun
  • You can get PVB in a variety of thicknesses.
  • A cost-effective laminate option.
  • You can mix and match PVB inter-layers.

EVA interlayer film

EVA is known as an alternative to safety glass, but it is not commonly used as PVB. As compared to PVB, EVA has more resistance against moisture, which can be considered for both internal and external glazed applications when the edges are exposed. You will have a lot of choices while you are choosing the color in EVA interlayer film.

Using EVA inter-layer film to make laminated glass, you can use different products like paper, decorative wire mesh, fabrics, printed PET films, and photovoltaic cells.

EVA Inter-layer film applications

Let’s talk about the applications of EVA interlayer.

  • Smart glass
  • Switch glass
  • Solar panels
  • Decorative laminated glass

EVA inter-layer film availability

EVA inter-layer is available in the following details:

  • Clear EVA
  • Tinted EVA
  • Colored EVA

Benefits of using EVA

Following are the benefits that you will have to consider EVA inter-layer film:

  • For exposed edge and external applications, EVA is the best option so far.
  • You can customize the material to add up more products if you are using EVA interlayer film.
  • EVA inter-layer is an affordable and more cost-effective option as compared to PVB interlayer film.

Find out which film is the best for you.

Going for interlayer film options can be confusing because most are similar in terms of looks. However, EVA brings much better options in terms of transparency, thermosetting, and several other aspects.
