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

Structure Options

Select the Sheet by Project Performance

The number and geometry of internal walls influence weight, stiffness, insulation, appearance and allowable span.

01

Twin-Wall Sheet

A simple two-wall hollow structure for lightweight glazing and general daylighting applications.

GreenhousesCanopies
02

Multiwall Sheet

Additional chambers can improve thermal insulation and structural behaviour for suitable projects.

SkylightsFacades
03

X-Structure Sheet

Diagonal internal ribs may provide increased rigidity where a reinforced hollow structure is required.

RoofingWalkways
04

Special Structure

Honeycomb and other chamber geometries can be reviewed against optical and structural requirements.

AccessoriesH/U profiles, sealing tape, fasteners and compatible componentsJoint, edge and installation details
PackingProtective film, sheets/bundles, pallets or project packingHandling, 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.

Hollow polycarbonate sheets used for greenhouse roofing

Greenhouses

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.

Frequently Asked Questions

PC Hollow Sun Sheet FAQ

What is another name for a PC hollow sun sheet?
Common names include hollow polycarbonate sheet, twin-wall polycarbonate sheet, multiwall polycarbonate sheet, sunlight sheet and hollow PC sheet. The exact wall structure should always be shown in the quotation or section drawing.
Which thickness should I choose?
Selection depends on wall structure, panel size, support spacing, wind and snow load, installation system and local requirements. Provide the project information rather than selecting by thickness alone.
Can hollow polycarbonate sheets be used outdoors?
Yes, when the correct outdoor grade and UV-protected surface are specified. Confirm whether UV protection is on one or both sides and install the marked side in the required direction.
Can the sheet length and colour be customized?
Custom length and colour can be reviewed according to the wall structure, production limitations, order quantity and approved sample. Confirm tolerances and colour standards before production.
How should the open chambers be sealed?
The sheet ends normally require compatible sealing and ventilation treatment to manage dust, moisture and condensation. The final system should follow the approved installation design and supplier guidance.
Do you supply profiles and accessories?
Matching H profiles, U profiles, tapes and selected fastening components can be discussed. Send the joint layout and edge details so compatibility can be checked.
What information is required for a quotation?
Provide the application, wall structure, thickness, dimensions, colour, UV side, optical requirement, quantity, accessories, documents, packing and destination port.
