Product Overview
What Is a PC Hollow Sun Sheet?
A PC hollow sun sheet is a multiwall polycarbonate panel formed with internal ribs and air chambers. It is also commonly described as a hollow polycarbonate sheet, twin-wall polycarbonate sheet, multiwall polycarbonate panel or sunlight sheet.
The chambered structure combines low weight, daylight transmission and better thermal performance than a single thin sheet. The correct wall structure, thickness, UV protection and support spacing must be selected for the actual project.
- Clear or coloured sheets
- Two-wall or multiwall
- One- or two-side UV option
- Cut-length review
- Matching profiles
- Export packaging
Structure Options
Select the Sheet by Project Performance
The number and geometry of internal walls influence weight, stiffness, insulation, appearance and allowable span.
Twin-Wall Sheet
A simple two-wall hollow structure for lightweight glazing and general daylighting applications.
GreenhousesCanopiesMultiwall Sheet
Additional chambers can improve thermal insulation and structural behaviour for suitable projects.
SkylightsFacadesX-Structure Sheet
Diagonal internal ribs may provide increased rigidity where a reinforced hollow structure is required.
RoofingWalkwaysSpecial Structure
Honeycomb and other chamber geometries can be reviewed against optical and structural requirements.

PC Hollow Sun Sheet Specifications
The table is a purchasing guide, not a fixed promise of stock. Confirm the exact structure, tolerances and test data before ordering.
| Item | Common options to discuss | What the buyer should confirm |
|---|---|---|
| Material | Polycarbonate (PC) | Required grade and supporting documents |
| Structure | Twin-wall, multiwall, X-structure or special chamber | Section drawing or approved sample |
| Thickness | Common market range includes 4–20 mm; other options by structure | Required thickness and tolerance |
| Width & length | Standard or project-specific production sizes | Finished size, cutting allowance and quantity |
| Colour | Clear, opal, blue, green, bronze and selected custom colours | Colour sample and light-transmission target |
| UV protection | One-side or two-side UV layer, subject to grade | Exposed side and installation orientation |
| Surface options | Clear, diffused, anti-drip or other functional option where available | Application and required performance |
| Accessories | H/U profiles, sealing tape, fasteners and compatible components | Joint, edge and installation details |
| Packing | Protective film, sheets/bundles, pallets or project packing | Handling, labels and destination port |
Engineering note: Thickness alone does not determine allowable span, wind load or snow load. The responsible designer must verify panel structure, support spacing, fixing method, thermal movement and local building requirements.
Colour & Optical Choice
Balance Daylight, Glare and Heat
Clear sheets are normally selected where higher daylight is important. Opal or tinted sheets can reduce direct glare and change solar heat gain. Final optical values must be tied to the exact colour, thickness and wall structure.

Applications
Where Hollow Polycarbonate Sheets Are Used
Every application requires a project-specific review of loading, supports, UV exposure, fire requirements, sealing and drainage.

Greenhouses
Lightweight daylight panels for commercial growing structures and garden greenhouses.

Canopies & Walkways
Weather-cover panels for entrances, paths, carports and connecting corridors.

Skylights & Daylighting
Translucent rooflights and wall panels designed to introduce natural light.
Swimming Pool Covers
Enclosure and cover projects after humidity, chemical exposure and ventilation are reviewed.
Industrial Rooflights
Daylight sections for commercial and industrial buildings with compatible support systems.
Partitions & Facades
Selected translucent wall and divider applications requiring lightweight multiwall panels.
Purchasing Comparison
Hollow vs Solid Polycarbonate Sheet
| Selection factor | PC hollow sun sheet | Solid polycarbonate sheet |
|---|---|---|
| Construction | Internal ribs and hollow air chambers | Continuous solid panel |
| Weight | Lower weight for a comparable nominal thickness | Heavier due to solid construction |
| Thermal behaviour | Air chambers support improved insulation | Depends mainly on solid thickness |
| Optical appearance | Ribs are visible; clear, diffused or tinted effect | Higher visual clarity with the correct grade |
| Typical use | Greenhouses, canopies, skylights and daylight walls | Guards, glazing, barriers and fabricated parts |
| Critical installation point | Seal chambers, orient ribs and allow drainage | Allow thermal movement and avoid stress concentration |
Order Workflow
From Requirement to Container Loading
Requirement Review
Confirm application, structure, thickness, dimensions, colour, quantity and destination.
Sample & Specification
Approve the chamber geometry, colour, optical appearance, UV side and tolerances.
Production & Inspection
Manufacture against the confirmed order and inspect agreed dimensions and appearance.
Packing & Shipment
Protect sheet surfaces and edges, then coordinate bundles, labels and container loading.
