High Performance Twinwall Polycarbonate Hollow Sheets for Global Commercial Projects
Our Polycarbonate Hollow Sheets are manufactured using advanced multi layer co extrusion technology. The unique hollow structure creates insulating air spaces that significantly reduce thermal transmission, making these panels the most energy efficient and lightweight alternative to traditional glass and solid roofing materials.
Why Volume Importers Choose Langfang Yansen Hollow Panels
Superior Thermal Insulation: The twinwall and multiwall design traps air to deliver excellent heat retention. This reduces heating and cooling costs for temperature controlled industrial plants, warehouses, and commercial agricultural greenhouses.
Advanced UV and Anti Yellowing Protection: Every sheet is coated with a high density UV absorption layer that blocks 99 percent of harmful ultraviolet rays. This prevents material degradation, maintains optical clarity, and extends the lifespan of the panels in high sunshine regions.
Lightweight and Easy Installation: Weighing only a fraction of solid glass, our hollow polycarbonate panels significantly reduce structural load requirements. They can be easily cold bent on site to accommodate curved roofs, domes, and modern architectural canopies.
Technical Specifications
Thickness: 4.0mm, 6.0mm, 8.0mm, 10mm, 12mm, 14mm, and 16mm. Standard Size: 2100mm width by 5800mm or 11800mm length to perfectly fit standard shipping containers. Light Transmittance: Reaches up to 80 percent for clear panels, providing soft and diffused natural light without creating harsh glare. Impact Resistance: High structural toughness that effectively protects against falling objects, heavy snow loads, and severe weather.
Applications
Commercial agricultural greenhouse roofing and modern hobby greenhouses. Industrial factory skylights, warehouse canopies, and walkway coverings. Carports, patio covers, swimming pool enclosures, and interior office partitions.

As a building material distributor supplying local farm greenhouse projects and residential canopy construction, I’ve sourced this twinwall polycarbonate hollow sheet for nearly one year, and I’d love to share my real using experience of this UV protected plastic roofing panel.
The biggest advantage of this polycarbonate hollow sheet is its double-sided UV protective coating. I used to purchase cheap uncoated PC panels from other suppliers, which turned yellow and became brittle within 1 year under strong sunlight. But this twinwall roofing panel keeps transparent and smooth after 10 months outdoor exposure on greenhouses and car canopies. The twin hollow structure brings excellent heat insulation, balancing the temperature inside greenhouses well; crops grow evenly without overheating at noon, which solves a big pain point for our farmer clients.
This plastic roofing panel is lightweight yet highly impact-resistant. It can withstand hail storms and heavy rain without cracking, far safer than fragile glass and easy-to-tear plastic film. It fits two core application scenarios perfectly: agricultural greenhouse covering and outdoor patio/car canopy roofing. We can customize thickness, length and colors based on customers’ project demands, and the factory arranges production quickly for bulk orders. Installation is convenient too—we can cut the sheets on site with regular tools, and matched sealing accessories are provided together to avoid roof leakage.
There are two minor flaws I encountered for true reference. First, a small number of sheets had slight scratches on the surface during long sea shipping due to thin protective film; after I contacted the sales team, they upgraded the packaging foam for my next order. Second, if the installation ventilation design is not handled properly, slight condensation may form inside the twinwall cavities in cold rainy seasons, which can be solved by following the detailed installation manual the supplier provides.
Overall, this UV protected twinwall polycarbonate hollow sheet is cost-effective and reliable for greenhouse and canopy roofing. All my repeat clients give positive feedback on its weather resistance and long service life. I will keep long-term cooperation with this supplier and highly recommend this plastic roofing panel to anyone engaged in agriculture or outdoor shading construction.

Very satisfied with these polycarbonate hollow sheets. Made of virgin PC resin with co-extruded UV layer, they stay clear without fading. Lightweight but high impact resistance—withstands strong wind and hail. Good thermal insulation helps save energy. We used clear 8mm for greenhouse and opal for carport. Perfect fit, easy installation.

As a customer sourcing materials for a commercial roofing project, these twinwall polycarbonate hollow sheets look like a very practical solution. The multi-layer co-extrusion process and hollow structure are especially appealing, as they provide both strength and thermal insulation without adding unnecessary weight.
From a project cost perspective, the lightweight nature of the panels can help reduce installation labor and structural load, which is a big advantage compared to traditional glass or solid sheets. The energy efficiency due to reduced heat transfer is also important for large-scale buildings where temperature control and long-term operational costs matter.
I also appreciate the focus on durability and suitability for global use. For warehouses, skylights, and industrial roofing, materials need to perform consistently under different climates, and these panels seem designed for that purpose. Overall, this product appears to be a reliable and cost-effective option for bulk buyers looking for performance and efficiency in one solution.

We are really impressed with these factory-direct polycarbonate hollow sheets. Made of pure virgin resin with co-extruded UV coating, they maintain good performance after long-term outdoor exposure. The twinwall structure brings excellent heat insulation and effectively avoids water dripping inside greenhouses. It resists hail, wind and fire well. With thickness ranging from 4mm to 16mm and rich color choices, it fully meets our different roofing needs. Great value for money.

We’ve installed these twin-wall polycarbonate sheets on several canopy and greenhouse projects, and the performance has been impressive. The hollow structure provides excellent thermal insulation while remaining lightweight and easy to install. The UV coating keeps the sheets clear and prevents yellowing even under strong sunlight. Compared with other brands we’ve used before, these panels offer better rigidity and long-term durability. Delivery was on time, packaging was secure, and every sheet arrived in perfect condition. We are happy with the quality and will continue working with this supplier for future roofing projects.
