In 2025, the worldwide construction industry keeps its focus on strength, effectiveness, and sustainability. This is especially true for roofing materials. For everything from family homes to big industrial sites and farm buildings, the need for top-quality corrugated roofing has never been greater. Among the leading options, UPVC roofing sheets and polycarbonate sheets are notable for their solid performance and wide-ranging uses.
Picking the right roofing material is vital. It’s not just for the first setup but for lasting performance. So, knowing the details, benefits, and best uses of UPVC and polycarbonate helps you make smart choices. This ensures you get the most value and sturdiness.
Unplasticized polyvinyl chloride (UPVC) roofing sheets are made to offer structural dependability with very little upkeep.
The core material for products like PVC/UPVC roof sheets and ASA synthetic resin roof tiles is PVC. It’s known for being tough and lasting. Crucially, UPVC has no plasticizers, which gives it a tougher and more solid form. These sheets also have stabilizers and pigments. These additions improve their ability to resist weather, UV light, and chemical damage.
People often choose UPVC roofing sheets because they are light. This makes them easier and faster to put up than old-style metal sheets. They are also rust-proof and handle wetness and chemicals very well. What’s more, UPVC provides great heat insulation. This is because PVC has a low thermal conductivity of 0.325 W/m.k—around 1/2000 that of colored steel. Plus, they give a good amount of sound insulation, cutting down noise by 25-30 dB when it rains.
Regular UPVC roofing is already trustworthy. But adding fiberglass reinforcement really boosts its performance to a new level.
A layer of fiberglass mesh is put inside the PVC/UPVC sheet. This internal mesh greatly improves the pulling strength and weight-bearing ability. It makes the sheets much better at resisting bending under high heat or heavy loads.
This strengthened type has much better tensile strength and impact resistance. The fiberglass mesh also improves dimensional stability. This makes sure the roof tiles stay firm during extreme weather and temperature shifts. All of this leads to a longer life, particularly in rough climates with lots of snow or strong winds.
Jieli’s fiberglass-reinforced UPVC sheet is a patented product. According to the company, they are the sole maker of this special technology in China. This unique layer design makes their UPVC roof sheets much stronger in high temperature resistance tensile strength, impact resistance, loading capacity, and weathering change resistance.
Polycarbonate sheets are another big name in the roofing world. They are famous for uses where letting light through is the main goal.
Polycarbonate is a thermoplastic known for its amazing impact resistance. People say it’s up to 250 times stronger than glass. It is much lighter, too. Its main quality is being very clear, which allows lots of light to pass through. It is also bendy, so it works well for curved building designs. However, normal polycarbonate sheets can scratch easily. They can also break down after a long time in the sun unless they have a protective coat. For better insulation, you can find multi-wall or twin-wall types.
Because they are see-through, polycarbonate corrugated sheets are often used for greenhouses, patio covers, and skylights. You also see them in sunrooms, carports, and covered walkways. Basically, they are the top choice for any project that needs plenty of natural light.
To decide between UPVC and polycarbonate, it’s key to compare their performance on a few different points.
In tough places, the roofing material’s toughness is everything. Glass fiber reinforced UPVC holds its shape and color in all kinds of weather. In contrast, while polycarbonate is very impact-resistant, it can turn yellow over time. This happens as its protective UV coat wears off, which can also make it more fragile.
Good thermal performance is vital for cutting energy bills. As mentioned, UPVC is a much better thermal insulator than standard solid polycarbonate. It’s a real benefit. For soundproofing, UPVC’s skill at muffling heavy rain noise is a big plus for homes and businesses. While multi-wall polycarbonate sheets give better thermal insulation, they usually can’t match the sound-blocking qualities of UPVC.
Generally, UPVC needs very little care. Its surface doesn’t get damaged easily, and it fights off chemical corrosion well. On the other hand, polycarbonate surfaces can get scratched and worn more easily. This can make them look cloudy. They might also need cleaning now and then to stay clear.
Material prices change, but polycarbonate can cost more at the start. When you think about its whole life value, the possible need to replace it because of UV damage can raise the total cost. Thus, the longer lifespan of glass fiber reinforced UPVC often means you get a better return on your money.
Different jobs need different materials. The choice depends on the place and what it’s used for.

When you’re looking for corrugated roofing materials, Jieli is a leader because of its new ideas and trustworthiness.
Jieli started in 1992. It is now one of the top makers of UPVC roof sheets in China. With its own special formulas and an in-house, government-approved testing lab certified by CMA, Jieli makes sure its products are always high quality. They work worldwide on big projects, like the Venezuelan housing project (220 containers). They also have long-term supply deals with Sodimac, a major building material chain in Latin America, since 2012.
For help in different languages or for technical advice, customers can reach Jieli through their official website. They also offer suggestions for specific projects, including drawings and material estimates, if you ask.
To sum up, glass fiber reinforced UPVC roofing sheets offer incredible sturdiness, fantastic thermal and acoustic insulation, and better value for the money. This makes them perfect for tough industrial, agricultural, and residential uses. While polycarbonate corrugated sheets are great for a special market of light-friendly structures like greenhouses or patios, their weaker insulation and tendency to get scratched and worn by UV light make them less useful for broader needs. With patented technology from solid suppliers like Jieli, reinforced UPVC roofing is a smart investment for long-lasting, resilient buildings.
Q1: How long does glass fiber reinforced UPVC roofing last?
A1: If installed correctly with little care, Jieli’s fiberglass-reinforced UPVC sheets can last over 25 years. This is because of their improved structural strength and weather resistance.
Q2: Can I use glass fiber reinforced UPVC sheets in coastal regions?
A2: Yes. These sheets are extremely resistant to salt corrosion. That makes them perfect for buildings near the ocean or in very humid areas.
Q3: Are glass fiber reinforced UPVC sheets environmentally friendly?
A3: Yes. They can be recycled and help save energy through their excellent thermal insulation properties. This lessens the need for air conditioning or heating systems.
