What Makes Polycarbonate Better Than Fiberglass?

There has been a long debate between which is better – polycarbonate or fiberglass. But, it comes to an end with this blog, which clearly proves that polycarbonate is the winner. Although a layman may not find a difference between the two materials, there are a whole lot of differences that you must know about, so that you can make a wise choice. Listed below are the reasons that prove polycarbonate roofing sheets to be better than fiberglass in every aspect.


Polycarbonate sheets are much cleaner to look at than fiberglass; and they don’t deteriorate in their appearance even when exposed to sunlight and other environmental conditions; this being the most important benefit of having a polycarbonate roof. No matter what kind of environment, and no matter what kind of modifications made to the roof, polycarbonates always maintain their clean look, while fiberglass will start looking dull relatively faster.


You always want your roof to be durable so that it can last longer, and you have to encounter no hassles of replacement or repair for years to come after installation. Here again, polycarbonate is the clear winner as it can withstand the harshest environmental conditions, may it be extreme climate, snowfall, heavy rain, UV rays, wind, or any other impact. Polycarbonate is used in bulletproof windows, so you can imagine how strong it may be! It has a tensile strength of 900 pounds per square inch, compared to the 220 pounds of fiberglass. We can clearly see how polycarbonate has more than four times the impact resistance of fiberglass.


The installation of polycarbonate is very easy and hassle-free, mainly because it is so lightweight and easy to carry. Polycarbonate weighs 40% lesser than fiberglass, thus making it easier to ship, carry, and install; resulting in cost-effectiveness too.

Health risks

Working with polycarbonates is much easier, cleaner, and harmless as compared to modifying fiberglass. Fiberglass is made of interwoven fibers which results in splintering when modified. Whether you want to drill a hole into the sheet, or cut small the size of the sheet, working with fiberglass can be irritable and harmful as the material produces dust that can irritate the skin and eyes, and is also dangerous to inhale. Polycarbonate, on the other hand, when cut or drilled, make the process easier and cleaner as the material produces small shavings that pose no health risks, and are also easy to clean.

UV resistance

When exposed to UV light for longer, fiberglass that is made of fibers starts to deteriorate and fade away gradually over time. On the other hand, polycarbonates are devoid of fibers, which means they can maintain their colour even when they are exposed to the UV radiations of the sun. Because roofs are exposed to prolonged periods of sunlight, installing polycarbonate roofing sheets should be the best option.

Possibility to reprocess

When fiberglass is broken or damaged, it is disposed as it is of no use then. Conversely, polycarbonate in the same case can be recycled and processed for re-use. This makes polycarbonate highly environment-friendly as compared to fiberglass.
