The Difference Between Fiberglass and Polycarbonate

There seems to be a lot of confusion between fiberglass and polycarbonate sheets. While both are viable options when it comes to replacing glass in builds and projects, the two are not interchangeable and are, in fact, two very different materials.

Today we’ll be sharing with you the key differences between fiberglass vs polycarbonate roofing to help you decide which one is right for you.

Polycarbonate Sheets

Polycarbonate sheets are a kind of thermoplastic that come in a wide range of colors and thicknesses. Polycarbonate sheets are made to allow light to pass through, whether you choose a sheet that’s opaque, translucent, or transparent.

It is made with UV coating, making it good for outdoor applications. This allows it to maintain its color and prevents it from turning yellow or discoloration despite its daily exposure to sunlight and UV rays.

Polycarbonate sheets are two hundred times stronger than glass of the same thickness and can withstand high-impact pressure. Despite being stronger than glass, they are significantly lighter, so it requires a cheaper framework to build.

Polycarbonate sheets are one of the more cost-effective materials in the market, making it very popular among builders. Despite its affordability, it is very durable and can last upwards of a decade. It also does not require a lot of maintenance or upkeep because of the way it was chemically treated.


Fiberglass, on the other hand, is a flame-resistant material that can be used for roofs or partitions. Like polycarbonate, it also comes in different colors, styles, and patterns. Unlike polycarbonate, however, fiberglass cannot withstand extreme heat.

Fiberglass is not suited for outdoor applications because its colors tend to deteriorate over time. Colors tend to become less saturated while clear fiberglass becomes yellow due to the exposure to UV rays.

Although fiberglass is cheaper than glass and tempered glass, it is still more expensive than polycarbonate sheets. It also costs quite a bit to install, repair, and maintain.

What is the Best Clear Roofing Material?

Because fiberglass tends to turn yellow when exposed to UV rays and is not suitable for hot temperatures, it is not a good option for roofing applications. We recommend sticking to polycarbonate sheets as they are heat-resistant, stay clear, and can weather any storm.

Which Roofing Sheet is the Best?

Well, that depends on the application and project. There are many different kinds of polycarbonate roofing sheets available, with one better suited to a certain application than another. For instance, Twin-wall Polycarbonate sheets are great for roofing, domes, skylights, and patios. Solid polycarbonate sheets, on the other hand, work well as window or door awnings, sound barriers, or indoor partitions.
