If you’re looking for a roofing or glazing material that combines lightweight design, superior insulation, and lasting strength, Hollow Polycarbonate Sheets are the answer. More than just a construction material, they represent a modern innovation that redefines transparency and durability in architectural and industrial applications. In this article, we’ll explore everything you need to know about Hollow Polycarbonate Sheets — their types, available colors, and key technical specifications — helping you choose the perfect solution for your next project with confidence.
As one of the leading manufacturers in the polycarbonate industry, G-Crystal Plastic Industries offers world-class hollow sheets tailored for every need.
What are Hollow Polycarbonate Sheets?
Hollow Polycarbonate Sheets, compliant with European standards, are lightweight, multi-layered plastic panels made from high-performance polycarbonate resin. Unlike solid sheets, they feature internal air chambers (or hollow cells) that enhance thermal insulation and reduce weight without compromising strength. This unique structure provides excellent impact resistance, UV protection, and light transmission, making them ideal for roofing, skylights, greenhouses, façades, and industrial glazing. Durable, energy-efficient, and easy to install, hollow polycarbonate sheets offer a cost-effective solution for projects that require both clarity and long-term weather resistance.
Key Features and Advantages of Hollow Polycarbonate Sheets
Hollow Polycarbonate Sheets offer the perfect balance between strength, insulation, and light transmission. Their unique multi-wall design makes them a top choice for industrial, commercial, and architectural projects.
- High Impact Resistance: Up to 250 times stronger than glass, ensuring safety and durability.
- Thermal Insulation: Air chambers reduce heat transfer, improving energy efficiency.
- Lightweight & Easy Installation: Easy to handle and transport, lowering structural load.
- UV & Weather Protection: Co-extruded UV layer prevents yellowing and aging.
- Excellent Light Transmission: Up to 85% natural light with soft diffusion.
- Sound Insulation: Multi-wall structure effectively reduces noise levels.
- Eco-Friendly & Long Lifespan: Recyclable material lasting over 15 years.
- Fire Resistance (B2 grade certified)
Each type is available in different thicknesses, colors, and light diffusion levels to suit both industrial and decorative uses.
Types of Hollow Polycarbonate Sheets
Here are the main types of Hollow Polycarbonate Sheets, each designed to meet specific performance and architectural needs:
- Twin Wall Polycarbonate Sheets
- The most common type, consisting of two layers separated by air chambers. They provide excellent thermal insulation, high light transmission, and are ideal for greenhouses, skylights, and wall partitions.
- Triple Wall Polycarbonate Sheets
Built with three layers for enhanced strength and insulation. They offer better rigidity, energy efficiency, and weather resistance, suitable for industrial roofing and architectural façades. - Multiwall Polycarbonate Sheets
These sheets include multiple air chambers (three or more) to maximize heat insulation and soundproofing. Commonly used in large-scale commercial projects, sports facilities, and conservatories. - Corrugated Hollow Polycarbonate Sheets
Combine a wavy or ribbed surface with hollow cells, providing superior rigidity, water drainage, and wind resistance — perfect for roofing, carports, and outdoor shelters.
Each type of Hollow Polycarbonate Sheet offers a balance between strength, insulation, and weight, allowing architects, contractors, and distributors to choose the right configuration for every professional project.

Production Process
At G-Crystal Plastic Industries, the production of Hollow Polycarbonate Sheets combines precision engineering with advanced extrusion technology. Using high-purity polycarbonate resin, the material is melted and formed through multi-layer extrusion lines to create uniform hollow cells that ensure strength, insulation, and clarity. Each sheet undergoes a UV coating process to enhance weather resistance and prevent yellowing over time. Before packaging, all products are thoroughly inspected to verify optical transparency, dimensional stability, and compliance with European CE standards and triple ISO certifications, guaranteeing consistent quality across every batch.
Packaging & Export Readiness
Every sheet produced by G-Crystal is meticulously packaged to ensure maximum protection during transportation and long-term storage. Both sides are covered with PE protective film, then stacked on reinforced wooden pallets and securely wrapped with waterproof material. For bulk shipments, customized labeling, barcoding, and pallet configurations are available according to client specifications. With exports to more than 60 countries worldwide, G-Crystal ensures that each order is fully export-ready, providing professional documentation, reliable logistics coordination, and flexible CIF or FOB shipping options to meet the needs of international distributors and importers.
