The use of glass in various types of projects is quite common. Among the most used are tempered and laminated, both being ideal when it comes to safety.

Despite the similarity between the two materials, some characteristics of each of them are capable of distinguishing them. So today you will know the difference between tempered glass and laminated glass. Follow next!

Tempered glass

Let's start by talking about tempered glass and its main features. To be produced, for example, the material undergoes a thermal treatment: it is placed in an oven heated to approximately 600ºC, and then cooled abruptly.

The process is essential to stiffen the structure of the material. In addition, it is responsible for providing five times greater resistance to thermal shock compared to common glass, being able to withstand large variations in temperatures. In relation to laminated glass, tempered glass is not very flexible.

Another notable feature of this material is that, after processing, it cannot be pierced or cut. If this happens, the part can be completely shattered, although the fragments are small and not very sharp.

Tempered is considered a safety glass, being widely used in windows, doors, showcases, bathroom boxes, stoves and partitions.

Laminated glass

Now, it's time to talk about the attributes of laminated glass, also classified as safety glass. Thus, it is easier to understand the main differences between it and tempered, starting with the manufacturing process, which is quite different.

In the case of laminate, there is the union of two or more plates, which can be of common or tempered glass. What unites the pieces are intermediate layers of PVB (Polyvinyl Butyral) films, forming a kind of sandwich. This process ensures that, in the event of damage to the material, the splinters remain glued to the film and do not come loose.

The PVB film is also responsible for filtering about 99% of ultraviolet rays, which can, in the long term, discolor objects present in the place, such as furniture and fabrics. Furthermore, the laminate reduces noise as it dampens sound vibrations through the layers of polyvinyl butyral.

A disadvantage compared to tempered is that laminate is less resistant to frontal impacts. Thus, it is more recommended to use it on floors, skylights, steps, handrails, guardrails and roofs.

Which one to choose for your project?

When deciding on the type of glass that will be used in your project, the most important thing is to evaluate where it will be installed. That way, you don't run the risk of choosing an unsuitable material for construction.

Regarding the cost, tempered glass is usually more advantageous, which does not mean that it is inferior in terms of safety. The big question is that laminate is more suitable for projects that require greater security, such as balconies and mezzanines.

Another option for those who want even more security is to use tempered laminated glass, which unites the attributes of both materials. It can be used, for example, on facades, steps, skylights and floors.

Therefore, assess the need for your project and find out which of the two materials is right for you.
