Polycarbonate, sometimes referred to as Lexan, is twice as light and 250 times stronger than standard glass and is therefore widely used for replacement glazing. In this blog, we&#;re going to take a look at the advantages and disadvantages of polycarbonate.
Key polycarbonate advantages
Fire-resistant
Vandal-proof
Hardwearing
Insulating
Lightweight

Polycarbonate disadvantages
Sensitive to scratches if misused
Advantage: polycarbonate is fire-resistant
Unlike acrylic sheet, polycarbonate is resistant to fire and has a fire rating of B1, which means that the material will not burn with an open flame. Polycarbonate is actually self-extinguishing.
Advantage: resistant to vandalism
Polycarbonate is virtually unbreakable and vandal-proof, making it the ideal choice of material for safety glazing. Examples include shelters, bicycle sheds, machines and technical products, illuminated signs and marine glazing.
Advantage: sustainable
Polycarbonate also scores highly in terms of sustainability. It has a long service lifespan and the panels are fully recyclable. Our polycarbonate sheets are also resistant to UV rays, making them suitable as a sheet material for exterior applications. Polycarbonate is perfect for a greenhouse, a boat window, basketball backboards or a terrace canopy.
Advantage: insulating
An important advantage of polycarbonate is that it retains heat very well so is ideal for greenhouses. A polycarbonate greenhouse creates an optimal microclimate for your plants.
Advantage: light in weight
Polycarbonate sheets are twice as light as standard glass. This makes it very easy to work with, especially for a project such as installing a patio canopy.
Advantage: easy to process
Polycarbonate is processed in in the same way as acrylic sheet. Whereas acrylic may sometimes melt if machined at too high a speed, there is no chance of this with polycarbonate. This material is stronger so that the risk of breakage is even lower than with molded acrylic sheet. Polycarbonate can be sawn, milled, engraved, drilled, bent (hot), glued and polished in the same way as acrylic sheet.
Disadvantage & Solutions: Sensitive to scratches and how to remove them.
The main disadvantage of polycarbonate is that it isn&#;t resistant to scratches. For example, if a branch should happen to fall on a patio canopy made of polycarbonate, it may be scratched. This problem can be solved by polishing the polycarbonate which will remove any scratches.

The safest material used by the construction industry is Polycarbonate sheet. In other words, polycarbonate is alternative for glass windows when it comes to construction. But why so? Glass breaks, and glass is much more difficult to handle, which make the cost higher, the construction industry is shifting towards more sustainable means. Polycarbonate sheet is a perfect material for glass substitute in glass window and glass roof.
Plastics fall into two main categories: thermoplastics and thermosets. Thermoplastics, as the name suggests, polycarbonate sheet is flexible, polycarbonate thermoforming is a very popular processing we used. Polycarbonate sheet is one such example of a thermoplastic that is used in the form of sheets in building and construction.
Polycarbonate sheets are one of the most durable types of sheets used in construction projects as unbreakable glass. If you throw a stone on your glass window, it will shatter into pieces. However, if you throw a piece of stone on your polycarbonate window, it won&#;t shatter like that. In fact, it will resist the force as much as it can. As much as the benefits of polycarbonate&#;s advantages, we also can&#;t ignore the disadvantages of polycarbonate sheet . And we will try to find best solution for the disadvantages.
Before talking about the drawbacks, let&#;s give you a context of polycarbonate sheets and how they have nearly replaced glass.
The invention of polycarbonate dates back to when a German chemist, Alfred Einhorn, was working on cyclic carbonates. Fast forward to the present, Polycarbonate is a type of plastic that belongs to the thermoplastic category. This kind of plastic is categorized by its extreme durability, clarity, impact resistance, and versatility.
In their original state, these sheets are transparent in color and made of polymer polycarbonate. Polymer polycarbonate is known to be a strong material perfect for the weather&#;s wear and tear. These sheets are mostly used in areas like windows, skylights, and greenhouses, where they are exposed to routine wear and tear in outdoor environments.
However, the application of polycarbonate sheets is not just limited to construction purposes but also expands to riot shields, safety glasses, safety helmets visors, and medical devices. In simple words, these are applicable almost everywhere where there is a need.
Moreover, besides its durability, polycarbonate sheets are available in a variety of thicknesses and colors. For example, if you need polycarbonate roofing for external purposes, so the thickness must be either 0.8mm-20mm. With such a thickness, this sheet will ensure heat and sound insulation. However, if you need it for windows, or machine guards purposes, you can get it in a thickness of 4mm to 10mm. Besides its size and color, it also comes with various types of coatings, for example, UV protection and IR Blocking.
Coating your polycarbonate sheets holds significant importance, not only for enhancing durability but also for unlocking potential energy savings.
